Either libmath is required or not.
I don't think it can be optional.
Why is it changed?

Same comment as in v1, you should check which linker is used.
This check is only for GNU ld 2.30.

> +if host_machine.system() != 'windows'

The definitive solution should be to compile all common EAL files.
Please explain what are the issues in the common files.
I think we should not remove them and fix them one by one.
You could provide a separate patch to skip some files for
making helloworld working.

Same comment as above, it should not be changed.

Why rte_common.h is moved first in the list?

Why kvargs is removed?

For this function and the others in this file,
please add a comment explaining this is a stub, not the expected result.
You can add a TODO or FIXME tag.

Instead of simply "override", you could explain that the other libraries
are not yet supported on Windows.

I don't like modifying this file.
Can we skip not supported directories inside the sub meson files?

I think these come as part of libc, it's just on Linux they are not in the
main libc library but need to be linked in separately.

https://en.wikipedia.org/wiki/C_mathematical_functions#libm

Therefore, this looks the best way of dealing with this.

I'm not aware of any better way to implement this in meson right now,
sadly. Through the compiler object we can get information about linker
flags, but not about the specific linker itself, since it is only called
through the compiler.

I believe that is exactly what this patch is trying to do - it's skipping
the files unneeded to get helloworld working, and the intention is to fix
them one by one and add them back in later. Perhaps this sort of change
should be a separate (precursor) patch where the cover letter can call this
out explicitly?

Again, I believe these actions are to disable the parts of DPDK that are
not needed to enable helloworld, allowing later patches to come in and fix
them.

Since we now mandate meson 0.47 we can use the "subdir_done()" function to
this.

They are workarounds to build helloworld.
It is good to have progress in the draft tree,
but I see no point in merging this in master.
I think we should separate patches which are doing definitive changes
from temporary workaround patches disabling some files.
It is not an issue to merge some patches for Windows which are not compiling.

Yes. I'd suggest changing the existing comment rather than adding a new one. Update it to point out that on some OS's the maths functions are in a separate library.

Bruce is right, both pthreads and math lib are not required for windows 
as the functionalities associated with them are a part of the standard 
library. Not having the check for pthread cause a warning at link time. 
I will update the comment in v3 as suggested.

Bruce is right, we only compile required header and source files in 
order to avoid compatibility errors on windows. Without these
change helloworld on windows would fail to compile. Adding windows 
specific implementations of the common headers and sources would
bloat up individual patches as well the number of patches. kvargs is 
removed as a dependency to have minimum viable product for helloworld.
If required for lcore mask, it'll added back in v3.

Please make separate patches for workarounds.
I am interested to push some patches which are really required in master,
but the workarounds should stay in the Windows draft repository.

Since on windows we only support clang, this check cause an error.
'ERROR:  Program or command 'ld' not found or not executable'
It is for this reason we excluded this check from the build flow.
Clang uses lld as linker from the LLVM project.

Include in the config file looks wrong.

I think we could remove the sub-directory exec-env.
Could we include this file from rte_common.h?

It is missing comments to explain the need of each line.

rte_windows.h defines types and substitution macros which are
needed to support common code on windows. So it should be
included as a global include for every library on windows.
rte_common.h is not included in all the source code and headers
we currently build for windows.

I think it is not an issue adding some rte_common.h include
here and there.

I'd be hesitant about putting it in rte_common.h without knowing the
scope of the changes - "here and there" could end up being "everywhere".

Another alternative is to see if most/all the definitions could actually be
put in dpdk_conf and thereby go into the standard config.h file generated
at build time. Anything that couldn't be done via macros or defines in the
config could then look to be put maybe in rte_common.h or other locations,
perhaps.

It's already almost everywhere, and I think it's normal,
it is the meaning of "common".

% git grep rte_common.h | wc -l
459

% git grep rte_common.h lib | fgrep .h: | wc -l
79

If some .c files doesn't have rte_common.h included directly or
indirectly from other includes, it may be fixed.

I think we should keep the semantic of what a config file is.
I don't see the need of adding more than strict config in it.

[dpdk-dev] [PATCH v2 3/6] eal: add headers for compatibility with windows environment

[Anand Rawat]

Added headers to support windows environment for common source.
These headers will have windows specific implementions of the
system library apis provided in linux and freebsd.

+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM* C compiler and linker.
+The Meson* Build system is used to prepare the sources
+for compilation with the Ninja backend.
+
+\*Other names and brands may be claimed as the property of others.
+
+Install the Compiler
+--------------------
+
+Download and install the clang compiler from `LLVM* website <http://releases.llvm.org/download.html>`_.
+For example, Clang-LLVM direct download link::
+
+	http://releases.llvm.org/7.0.1/LLVM-7.0.1-win64.exe
+
+
+Install the Build System
+------------------------
+
+Download and install the build system from `Meson's website<http://mesonbuild.com/Getting-meson.html>`_.
+A good option to choose is the MSI installer for both meson and ninja together::
+
+	http://mesonbuild.com/Getting-meson.html#installing-meson-and-ninja-with-the-msi-installer%22
+
+Install the Backend
+-------------------
+
+If using Ninja, download and install the backend from `Ninja's website<https://ninja-build.org/>`_ or
+install along with the meson build system.
+
+Build the code
+--------------
+
+The build environment is setup to build the EAL and the helloworld example by
+default.
+
+Using the ninja backend
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk
+    meson build
+    cd build
+    ninja
+
+Run the helloworld example
+==========================
+
+Navigate to the build directory and run `dpdk-helloworld.exe`.
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk\build
+    helloworld.exe
+    hello from core 1
+    hello from core 3

+Introduction
+============
+
+This document contains instructions for installing and configuring the Data
+Plane Development Kit (DPDK) software. The document describes how to compile
+and run a DPDK application in a Windows* OS application environment, without
+going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source files
+compile. Support is being added in pieces so as to limit the overall scope
+of any individual patch series. The goal is to be able to run any DPDK
+application natively on Windows.

I think, there is one more dependency with link.exe or so.
Could you please check the log and update the documentation.

Out of interest, can you try with "meson -Dc_link_args=-fuse-lld build"? 

Re: [dpdk-dev] [PATCH v2 6/6] doc: add documention for windows

[Raslan Darawsheh]

Hi,
I've been trying to compile it as well without installing the VS stuff.
But, it's always failing to compile:
Even the sanitycheck.c file is failing with such error:
lld-link.exe: error: could not open libcmt.lib: no such file or directory

Kindest regards,
Raslan Darawsheh

This is correct, link.exe is needed by clang on windows.
I will update the document in V3 to reflect that. We
were able to build by using only the buildtools from
vs2017 and not the whole installation.

About the method, two advices:

- Please reply to the questions asked during the review
of the previous version before doing a new version.
It is with discussion that we can find the best solutions.

- Please use --in-reply-to for new revisions in order to have
all revisions in the same mail thread.
The best is to make all revisions as replies of the first cover letter.

Apologies, my email client was not setup to respond
as per the community guidelines. There will be more interaction
for v2

I will make sure to follow this from v3 onward.
Since now that there two cover letters, which one would you like
me to have --in-reply-to for v3

+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM* C compiler and MSVC* linker.
+The Meson* Build system is used to prepare the sources for compilation with the Ninja backend.
+
+\*Other names and brands may be claimed as the property of others.
+
+Install the Compiler
+--------------------
+
+Download and install the clang compiler from `LLVM* website <http://releases.llvm.org/download.html>`_.
+For example, Clang-LLVM direct download link::
+
+	http://releases.llvm.org/7.0.1/LLVM-7.0.1-win64.exe
+
+
+Install the Linker
+------------------
+
+Download and install the Build Tools for Visual Studio to link and build the files
+on windwos, from `Microsoft* website <https://visualstudio.microsoft.com/downloads>`_.
+
+
+Install the Build System
+------------------------
+
+Download and install the build system from `Meson* website <http://mesonbuild.com/Getting-meson.html>`_.
+A good option to choose is the MSI installer for both meson and ninja together::
+
+	http://mesonbuild.com/Getting-meson.html#installing-meson-and-ninja-with-the-msi-installer%22
+
+Install the Backend
+-------------------
+
+If using Ninja, download and install the backend from `Ninja* website <https://ninja-build.org/>`_ or
+install along with the meson build system.
+
+Build the code
+--------------
+
+The build environment is setup to build the EAL and the helloworld example by
+default.
+
+Using the ninja backend
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk
+    meson build
+    cd build
+    ninja
+
+Run the helloworld example
+==========================

+Navigate to the build directory and run `dpdk-helloworld.exe`.

+Introduction
+============
+
+This document contains instructions for installing and configuring the Data
+Plane Development Kit (DPDK) software. The document describes how to compile
+and run a DPDK application in a Windows* OS application environment, without
+going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source files
+compile. Support is being added in pieces so as to limit the overall scope
+of any individual patch series. The goal is to be able to run any DPDK
+application natively on Windows.

[dpdk-dev] [PATCH v3 8/8] build: meson changes to build on windows

[Anand Rawat]

Added meson workarounds to build helloworld on windows.
Windows currently only supports kvargs and eal libraries.
This change restricts the build flow to supported libraries
only.

[dpdk-dev] [PATCH v3 8/8] build: meson changes to build on windows

[Anand Rawat]

Added meson workarounds to build helloworld on windows.
Windows currently only supports kvargs and eal libraries.
This change restricts the build flow to supported libraries
only.

[dpdk-dev] [PATCH v4 0/8] HelloWorld example for windows

[Anand Rawat]

Includes Windows-specific EAL changes and meson changes
to build the code on windows.

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file
2. Moved disabling meson logic to sub directories

v3 Changes:
1. Separated meson workarounds from the essential code changes
2. Added support for kvargs
3. Updated meson for building DLL on windows using DEF files
4. Fixed documentation for html links and linker dependency
5. Added comments for windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for windows branch

notes:
*patch 8/8 contains meson workarounds to build helloworld
on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result
lcore mask is currently not supported.

Anand Rawat (8):
  eal: eal stub to add windows support
  eal: add header files to support windows
  kvargs: adding a module definition file
  eal: sys/queue.h implementation for windows
  eal: add headers for compatibility with windows environment
  eal: add minimum viable code for eal on windows
  doc: add documention for windows
  build: meson changes to build on windows

+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM* C compiler and MSVC* linker.
+The Meson* Build system is used to prepare the sources for compilation with the Ninja backend.
+
+\*Other names and brands may be claimed as the property of others.
+
+Install the Compiler
+--------------------
+
+Download and install the clang compiler from `LLVM* website <http://releases.llvm.org/download.html>`_.
+For example, Clang-LLVM direct download link::
+
+	http://releases.llvm.org/7.0.1/LLVM-7.0.1-win64.exe
+
+
+Install the Linker
+------------------
+
+Download and install the Build Tools for Visual Studio to link and build the files
+on windwos, from `Microsoft* website <https://visualstudio.microsoft.com/downloads>`_.
+
+
+Install the Build System
+------------------------
+
+Download and install the build system from `Meson* website <http://mesonbuild.com/Getting-meson.html>`_.
+A good option to choose is the MSI installer for both meson and ninja together::
+
+	http://mesonbuild.com/Getting-meson.html#installing-meson-and-ninja-with-the-msi-installer%22
+
+Install the Backend
+-------------------
+
+If using Ninja, download and install the backend from `Ninja* website <https://ninja-build.org/>`_ or
+install along with the meson build system.
+
+Build the code
+--------------
+
+The build environment is setup to build the EAL and the helloworld example by
+default.

+Using the ninja backend
+~~~~~~~~~~~~~~~~~~~~~~~~

# I think, Build tools does not have link.exe. Based on my testing, I
need to install Micro soft Visual studio community edition get the
link.exe.

For instance, in my case, link.exe is installed in following URL in
Visual Studio, not anywhere in build tools path.

C:\Program Files (x86)\Microsoft Visual
Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\Hostx64\x64

If it is correct then doc needs to be updated.

Yes, they are, and, in my investigations anyway, I haven't found any way to
get rid of them. The meson support for windows is very much targetted at
users of msvc and clang-cl (which uses the msvc-style flags) rather than
regular clang, so the support is not as clean as I would like. Thankfully,
though, it does appear to be working thus far! :-)

Thanks, Bruce. Yes, few warnings are expected for now.

Regarding link.exe, will update the docs to install the build tools and 
select the 'Visual C++ build tools' option which also installs the 
linker and SDK required to build on windows.

Doing so, link.exe can be installed in the following URL and installing 
Visual Studio can be avoided.

Thanks, Bruce. Yes, few warnings are expected for now.

Regarding link.exe, will update the docs to install the build tools and 
select the 'Visual C++ build tools' option which also installs the 
linker and SDK required to build on windows.

Doing so, link.exe can be installed in the following URL and installing 
Visual Studio can be avoided.

This isn't really necessary, I think, since the docs are not built by
default. I think we should just document the fact that you can't turn on
the doc building in windows.

I think a better fix here is to create a windows subdirectory and put an
empty meson.build file there. Alternatively just document that for windows
you need to disable kernel module building.

Why is the common_headers list split into two? The headers should need no
adjustment in order to get things building, the header lists are only used
for the install phase, not the build one.

I think a better fix here is to create a windows subdirectory and put an
empty meson.build file there. Alternatively just document that for windows
you need to disable kernel module building.

Why is the common_headers list split into two? The headers should need no
adjustment in order to get things building, the header lists are only used
for the install phase, not the build one.

This change is unnecessary, as there is no build work being done here, just
configuring files for installation.

Subject: [dpdk-dev] [PATCH v4 0/8] HelloWorld example for windows

Includes Windows-specific EAL changes and meson changes to build the code on windows.

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file 2. Moved disabling meson logic to sub directories


v3 Changes:
1. Separated meson workarounds from the essential code changes 2. Added support for kvargs 3. Updated meson for building DLL on windows using DEF files 4. Fixed documentation for html links and linker dependency 5. Added comments for windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for windows branch

notes:
*patch 8/8 contains meson workarounds to build helloworld on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result lcore mask is currently not supported.

  eal: eal stub to add windows support
  eal: add header files to support windows
  kvargs: adding a module definition file
  eal: sys/queue.h implementation for windows
  eal: add headers for compatibility with windows environment
  eal: add minimum viable code for eal on windows
  doc: add documention for windows

IMO, Updating the rte_common.h for each execution environment is not
clean and unnecessary #ifdef clutter in the common code.

I think, it can be fixed by adding new os or eal specific header file
at the following location and simply include it(without any #ifdef)

lib/librte_eal/linux/eal/include/exec-env/rte_eal.h
lib/librte_eal/freebsd/eal/include/exec-env/rte_eal.h

It can be rte_eal.h or rte_os.h or anything similar.

IMO, Updating the rte_common.h for each execution environment is not
clean and unnecessary #ifdef clutter in the common code.

I think, it can be fixed by adding new os or eal specific header file
at the following location and simply include it(without any #ifdef)

lib/librte_eal/linux/eal/include/exec-env/rte_eal.h
lib/librte_eal/freebsd/eal/include/exec-env/rte_eal.h
lib/librte_eal/windows/eal/include/exec-env/rte_eal.h # the content of
exiting rte_windows.h goes here.

It can be rte_eal.h or rte_os.h or anything similar.

This was done based on a suggestion from Thomas:
(http://patches.dpdk.org/patch/50844/)

But, I agree. Your suggestion would be a good enhancement. There is 
already an existing rte_eal.h in common/include, so an rte_os.h or 
something similar might make sense.

I can include this change in v6. I am looking to add rte_os.h under
windows/eal/include/exec-env/ and include the header in rte_common.h
as a separate patch. This change would require new files for linux and freebsd.
What be should be the content of that?

I can include this change in v6. I am looking to add rte_os.h under
windows/eal/include/exec-env/ and include the header in rte_common.h

Maintaining two separate files (.map and .def) for shared 
library definition will be pain full.

Yes, though I'd question how much more painful it is than having to update
a separate map file anyway - just consider the number of patches that have
been submitted over the years which failed shared library build because map
file updates were forgotten.

However, my hope is that down the road we can have the def file generated
from the map file (or potentially vice versa). Perhaps the meson python
module could be used to allow us to script it a bit.

A wider question is whether it is possible at all to have ABI versions
associated with functions? I didn't find any mention of it in the
documentations, and if it's not possible, then the question of how to put
an experimental version is moot, I think.

It is painful due to the fact that, If it is windows ONLY file then
developer need to test on Windows as well as it may break Windows.
If it is a common file, at least, it will be tested on one platform.
So responsibly wise it is a clean partition between windows eal
maintainers vs generic library maintainers.

Make sense. Do we want to support shared lib for Windows for the first
version? or Can we live with static lib till we find a proper solution.
I do believe the base Windows Helloworld support needs to added this
release in main repo and add the subsequent features step by step.
I would treat, shared lib as subsequent feature if it is not clean.

Why?
We can just document it as broken, and test only "static" compilation.
Am I missing something?

Yes, static compilation also builds the shared libraries too. To turn that
off, you'd have to modify the meson.build files to conditionally undefine
the shared library builds on windows. Then undefine out the assignment to
any dependency variables that are using those libraries, etc. It's doable,
but it's a lot messier than adding in 2 .def files.

Yes, good point. However, once we get some windows support into the main
repo then there is the requirement not to break that, so some testing on
windows before merge will prove necessary. Hopefully that can be done just
via CI, rather than having maintainers/committers do so manually.

Yes, I did consider that possibility. However, turning off shared builds
for windows is more of a hack than adding a definition file, since it
involves more (temporary) changes to the meson.build for both lib and
driver.  If I get the chance, I'll see how complicated it might be to
autogenerate them at build. Otherwise, I'd suggest keeping the .def files
for now, since only 2 libraries are involved, but then we need to come up
with a proper solution before the number of libraries compiled on windows
goes above that initial 2.

Ok, some hacking has led to this as a possible approach to solve this. I've
only tested this on linux to verify it creates something approximating a
module definition file but not actually tried using it on windows. The nice
thing about meson being based on python is that we are guaranteed to have a
python3 interpreter available on whatever os we are running on. [Yes, I
made the script python2 compatible too, though I probably didn't need to!]

I've also included in this version an (untested) override option for EAL,
to allow us to keep the .def file for EAL until we can export all the
functions listed in the map file for it. Other libraries shouldn't need
this, since they aren't as insanely big as EAL.

Ok, some hacking has led to this as a possible approach to solve this. I've
only tested this on linux to verify it creates something approximating a
module definition file but not actually tried using it on windows. The nice
thing about meson being based on python is that we are guaranteed to have a
python3 interpreter available on whatever os we are running on. [Yes, I
made the script python2 compatible too, though I probably didn't need to!]

I've also included in this version an (untested) override option for EAL,
to allow us to keep the .def file for EAL until we can export all the
functions listed in the map file for it. Other libraries shouldn't need
this, since they aren't as insanely big as EAL.

I agree with Bruce, adding the two def files is the cleaner option and 
involves the least amount of changes in the common build flow. But if 
required shared library logic can be disabled as a part of meson 
workaround for windows for the initial release.

Even better would be to get it as a dependency outside of DPDK.
Where this code come from?
How other projects on Windows get it?

It comes from FreeBSD 12.0, specifically
  https://github.com/freebsd/freebsd/blob/releng/12.0/sys/sys/queue.h

It has been modified such that only the parts used by DPDK (i.e. TAILQ) are
implemented. The other stuff has been deleted. Windows does not have sys/queue.h,
so we reproduce it here.

Would it better to have this as a dependency outside of DPDK? I think pulling a file
from the internet and applying a patch (where we'd have to maintain a patch file
inside of DPDK's repo anyway) would be overkill when we just need a few lines of
code that will change very infrequently.

We already try to get the libbsd dependency on Linux.
Why not mandate libbsd for Windows?
It has this header file and a lot more:
	https://gitlab.freedesktop.org/libbsd/libbsd/blob/master/include/bsd/sys/queue.h

Relying on libbsd may avoid copying other files for Windows port.

I like that idea, though it doesn't look like libbsd builds on Windows, do you
know of a Windows version or one that doesn't depend on autotools to build?

It seems libbsd is not packaged for Windows.
May be worth to ask opinions to libbsd maintainers.

Please could you list which other headers are required for the Windows port?

For helloworld the only one is sys/queue.h.

The dpdk-draft-windows repo has at least these (non-empty) ones:
  dirent.h
  getopt.h
  net/ethernet.h
  net/socket.h
  netinet/in.h
  netinet/tcp.h
  pthread.h
  rand48.h
  sched.h
  sys/_iovec.h
  sys/_sockaddr_storage.h
  sys/_termios.h
  sys/_types.h
  sys/cdefs.h
  sys/mman.h
  sys/netbsd/queue.h
  sys/queue.h
  sys/sysctl.h
  syslog.h
  termios.h
  unistd.h

There will likely be more as more libraries are identified with dependencies on UNIX-like
headers.

How other cross-platform projects are getting such dependencies?
Is Cygwin a solution?

I agree. I think the EAL is supposed to do this, however the current implementation generally
assums a UNIX OS under the EAL. The libbsd might be a possiblity.

> How other cross-platform projects are getting such dependencies?

One example is Python. I just briefly reviewed the code and they go through great lengths to
abstract the OS and implement custom, OS independent layers wherever required (e.g. sockets,
getopt). See Modules/posixmodule.c for a 14K LOC example.

Another example is Nginx. The underlying OS is always abstracted with disparate implementations
for, e.g. unix & windows. See src/os/unix and src/os/win32. An example is the "socket()" call
on unix, nginx "core" would call "ngx_socket()" which is a macro that is defined to use
"WSASocketW" on windows, and "socket" on unix.

I think the goal is to be a native Windows application.

I agree. I think the EAL is supposed to do this, however the current implementation generally
assums a UNIX OS under the EAL. The libbsd might be a possiblity.

> How other cross-platform projects are getting such dependencies?

One example is Python. I just briefly reviewed the code and they go through great lengths to
abstract the OS and implement custom, OS independent layers wherever required (e.g. sockets,
getopt). See Modules/posixmodule.c for a 14K LOC example.

Another example is Nginx. The underlying OS is always abstracted with disparate implementations
for, e.g. unix & windows. See src/os/unix and src/os/win32. An example is the "socket()" call
on unix, nginx "core" would call "ngx_socket()" which is a macro that is defined to use
"WSASocketW" on windows, and "socket" on unix.

I think the goal is to be a native Windows application.

Yes, EAL is supposed to be the layer hiding the OS specifics.
It would be interesting to check how much libbsd may help EAL.

+Introduction
+============
+
+This document contains instructions for installing and configuring the Data
+Plane Development Kit (DPDK) software. The document describes how to compile
+and run a DPDK application in a Windows* OS application environment, without
+going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source files
+compile. Support is being added in pieces so as to limit the overall scope
+of any individual patch series. The goal is to be able to run any DPDK

+Introduction
+============
+
+This document contains instructions for installing and configuring the 
+Data Plane Development Kit (DPDK) software. The document describes how 
+to compile and run a DPDK application in a Windows* OS application 
+environment, without going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source 
+files compile. Support is being added in pieces so as to limit the 
+overall scope of any individual patch series. The goal is to be able to 
+run any DPDK application natively on Windows.

+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM* C compiler and MSVC* linker.
+The Meson* Build system is used to prepare the sources for compilation with the Ninja backend.

Subject: [dpdk-dev] [PATCH v5 0/8] HelloWorld example for windows

Includes Windows-specific EAL changes and meson changes to build the code on windows.

v5 Changes:
1. Reduced meson workrounds for windows.
2. Updated documention to include details about buildtool options

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file 2. Moved disabling meson logic to sub directories

v3 Changes:
1. Separated meson workarounds from the essential code changes 2. Added support for kvargs 3. Updated meson for building DLL on windows using DEF files 4. Fixed documentation for html links and linker dependency 5. Added comments for windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for windows branch

notes:
*patch 8/8 contains meson workarounds to build helloworld on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result lcore mask is currently not supported.

*kernel modules and documentation can not be built on windows currently and should not be enabled.

Anand Rawat (8):
  eal: eal stub to add windows support
  eal: add header files to support windows
  kvargs: adding a module definition file
  eal: sys/queue.h implementation for windows
  eal: add headers for compatibility with windows environment
  eal: add minimum viable code for eal on windows
  doc: add documention for windows
  build: meson changes to build on windows

1. Introduced rte_os.h for esstential os specific macros and typedefs.
2. Fixed commit typos and 'new line required at eof' issues.

v5 Changes:
1. Reduced meson workrounds for windows.
2. Updated documention to include details about buildtool options

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file
2. Moved disabling meson logic to sub directories

v3 Changes:
1. Separated meson workarounds from the essential code changes
2. Added support for kvargs
3. Updated meson for building DLL on windows using DEF files
4. Fixed documentation for html links and linker dependency
5. Added comments for windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for windows branch

notes:
*patch 3/8 contains module definition files and meson changes
required to build shared libraries on windows. These may be removed
in the future releases to be generated from the existing .map files.

*patch 8/8 contains meson workarounds to build helloworld
on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result
lcore mask is currently not supported.

*kernel modules and documentation can not be built on windows 
currently and should not be enabled.

[dpdk-dev] [PATCH v6 0/8] HelloWorld example for windows

[Anand Rawat]

Includes Windows-specific EAL changes and meson changes
to build the code on windows.

v6 Changes:
1. Introduced rte_os.h for esstential os specific macros and typedefs.
2. Fixed commit typos and 'new line required at eof' issues.

v5 Changes:
1. Reduced meson workrounds for windows.
2. Updated documention to include details about buildtool options

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file
2. Moved disabling meson logic to sub directories

v3 Changes:
1. Separated meson workarounds from the essential code changes
2. Added support for kvargs
3. Updated meson for building DLL on windows using DEF files
4. Fixed documentation for html links and linker dependency
5. Added comments for windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for windows branch

notes:
*patch 3/8 contains module definition files and meson changes
required to build shared libraries on windows. These may be removed
in the future releases to be generated from the existing .map files.

*patch 8/8 contains meson workarounds to build helloworld
on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result
lcore mask is currently not supported.

*kernel modules and documentation can not be built on windows 
currently and should not be enabled.
Anand Rawat (8):
  eal: eal stub to add windows support
  eal: add header files to support os specifics
  build: add module definition file for windows
  eal: sys/queue.h implementation for windows
  eal: add headers for compatibility with windows
  eal: add minimum viable code for eal on windows
  doc: add documentation for windows
  build: meson changes to build on windows

+
+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM* C compiler and MSVC* linker.
+The Meson* Build system is used to prepare the sources for compilation with the Ninja backend.
+
+\*Other names and brands may be claimed as the property of others.
+
+Install the Compiler
+--------------------
+
+Download and install the clang compiler from `LLVM* website <http://releases.llvm.org/download.html>`_.
+For example, Clang-LLVM direct download link::
+
+	http://releases.llvm.org/7.0.1/LLVM-7.0.1-win64.exe
+
+
+Install the Linker
+------------------
+
+Download and install the Build Tools for Visual Studio to link and build the files on windows, from `Microsoft* website <https://visualstudio.microsoft.com/downloads>`_.
+When installing build tools, select the "Visual C++ build tools" option and ensure the Windows SDK is selected.
+
+
+Install the Build System
+------------------------
+
+Download and install the build system from `Meson* website <http://mesonbuild.com/Getting-meson.html>`_.
+A good option to choose is the MSI installer for both meson and ninja together::
+
+	http://mesonbuild.com/Getting-meson.html#installing-meson-and-ninja-with-the-msi-installer%22
+
+Install the Backend
+-------------------
+
+If using Ninja, download and install the backend from `Ninja* website <https://ninja-build.org/>`_ or
+install along with the meson build system.
+
+Build the code
+--------------
+
+The build environment is setup to build the EAL and the helloworld example by
+default.
+
+Using the ninja backend
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk
+    meson build
+    cd build
+    ninja
+
+Run the helloworld example
+==========================
+
+Navigate to the build directory and run `dpdk-helloworld.exe`.
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk\build
+    helloworld.exe
+    hello from core 1
+    hello from core 3
+    hello from core 0

+Introduction
+============
+
+This document contains instructions for installing and configuring the Data
+Plane Development Kit (DPDK) software. The document describes how to compile
+and run a DPDK application in a Windows* OS application environment, without
+going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source files
+compile. Support is being added in pieces so as to limit the overall scope
+of any individual patch series. The goal is to be able to run any DPDK
+application natively on Windows.

+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM* C compiler and MSVC* linker.
+The Meson* Build system is used to prepare the sources for compilation with the Ninja backend.
+
+\*Other names and brands may be claimed as the property of others.
+
+Install the Compiler
+--------------------
+
+Download and install the clang compiler from `LLVM* website <http://releases.llvm.org/download.html>`_.
+For example, Clang-LLVM direct download link::
+
+	http://releases.llvm.org/7.0.1/LLVM-7.0.1-win64.exe
+
+
+Install the Linker
+------------------
+
+Download and install the Build Tools for Visual Studio to link and build the files on windows, from `Microsoft* website <https://visualstudio.microsoft.com/downloads>`_.
+When installing build tools, select the "Visual C++ build tools" option and ensure the Windows SDK is selected.
+
+
+Install the Build System
+------------------------
+
+Download and install the build system from `Meson* website <http://mesonbuild.com/Getting-meson.html>`_.
+A good option to choose is the MSI installer for both meson and ninja together::
+
+	http://mesonbuild.com/Getting-meson.html#installing-meson-and-ninja-with-the-msi-installer%22
+
+Install the Backend
+-------------------
+
+If using Ninja, download and install the backend from `Ninja* website <https://ninja-build.org/>`_ or
+install along with the meson build system.
+
+Build the code
+--------------
+
+The build environment is setup to build the EAL and the helloworld example by
+default.
+
+Using the ninja backend
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk
+    meson build
+    cd build
+    ninja
+
+Run the helloworld example
+==========================
+
+Navigate to the build directory and run `dpdk-helloworld.exe`.
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk\build
+    helloworld.exe

+Introduction
+============
+
+This document contains instructions for installing and configuring the Data
+Plane Development Kit (DPDK) software. The document describes how to compile
+and run a DPDK application in a Windows* OS application environment, without
+going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source files
+compile. Support is being added in pieces so as to limit the overall scope
+of any individual patch series. The goal is to be able to run any DPDK
+application natively on Windows.

+Introduction
+============
+
+This document contains instructions for installing and configuring the 
+Data Plane Development Kit (DPDK) software. The document describes how 
+to compile and run a DPDK application in a Windows* OS application 
+environment, without going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source 
+files compile. Support is being added in pieces so as to limit the 
+overall scope of any individual patch series. The goal is to be able to 
+run any DPDK application natively on Windows.

It is OK to merge few limited workarounds in the master branch,
in order to start compiling something on Windows,
and regularly check that the work done is not broken
by other patches coming in.
It will be especially useful if we manage to have a CI for Windows.

As discussed over the phone, it would be better to overwrite this list
and keep the original one as is.

Subject: [dpdk-dev] [PATCH v6 8/8] build: meson changes to build on windows

Added meson workarounds to build helloworld on windows.
Windows currently only supports kvargs and eal libraries.
This change restricts the build flow to supported libraries only.

Subject: [dpdk-dev] [PATCH v6 0/8] HelloWorld example for windows

Includes Windows-specific EAL changes and meson changes to build the code on windows.

v6 Changes:
1. Introduced rte_os.h for esstential os specific macros and typedefs.
2. Fixed commit typos and 'new line required at eof' issues.

v5 Changes:
1. Reduced meson workrounds for windows.
2. Updated documention to include details about buildtool options

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file 2. Moved disabling meson logic to sub directories

v3 Changes:
1. Separated meson workarounds from the essential code changes 2. Added support for kvargs 3. Updated meson for building DLL on windows using DEF files 4. Fixed documentation for html links and linker dependency 5. Added comments for windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for windows branch

notes:
*patch 3/8 contains module definition files and meson changes required to build shared libraries on windows. These may be removed in the future releases to be generated from the existing .map files.

*patch 8/8 contains meson workarounds to build helloworld on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result lcore mask is currently not supported.

*kernel modules and documentation can not be built on windows currently and should not be enabled.

[dpdk-dev] [PATCH v7 0/8] HelloWorld example for windows

[Anand Rawat]

Includes Windows-specific EAL changes and meson changes
to build the code on windows.

v7 Changes:
1. Fixed rte_os.h not found issue on linux and freebsd.
2. Fixed missing def issues on linux and freebsd.
3. Updated comments in header files to be more descriptive 

v6 Changes:
1. Introduced rte_os.h for esstential os specific macros and typedefs.
2. Fixed commit typos and 'new line required at eof' issues.

v5 Changes:
1. Reduced meson workrounds for windows.
2. Updated documention to include details about buildtool options

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file
2. Moved disabling meson logic to sub directories

v3 Changes:
1. Separated meson workarounds from the essential code changes
2. Added support for kvargs
3. Updated meson for building DLL on windows using DEF files
4. Fixed documentation for html links and linker dependency
5. Added comments for windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for windows branch

notes:
*patch 3/8 contains module definition files and meson changes
required to build shared libraries on windows. These may be removed
in the future releases to be generated from the existing .map files.

*patch 8/8 contains meson workarounds to build helloworld
on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result
lcore mask is currently not supported.

*kernel modules and documentation can not be built on windows 
currently and should not be enabled.

The library is "libm", not "liblm" so this breaks the linux builds as there
is not found an "lm" library. Instead use "cc.find_library('m',..."

I'm a little uncertain behind putting the stub files and the meson.build
changes in the one patch, since the result doesn't build anyway. However,
you can get meson to successfully configure the project on windows by
adding in an empty file called meson.build to the kernel/windows directory.

Thanks Bruce, libm is a part of V8 fixes.
kernel/windows directory is the patch 8/8 as I thought of it as a 
temporary workaround. I'll move it to another patch along with meson 
changes here.

Oh, I wasn't thinking of it being temporary, as I assumed you had kernel
modules for uio on windows. However, if they are not being hosted on DPDK,
I still think having a directory with a meson.build file with just a
comment in it e.g. "No kernel drivers for this OS",  is probably tidier
than having if conditions in the higher level build files.

Please write OS (uppercase) in this comment and others,
so we can understand it is an acronym.

> +#include <rte_os.h>

You don't prefix with exec-env/ sub-directory, unlike what is done
for rte_kni_common.h, and I think it is a good idea.
However it will require one more patch to make it work with
the make-based system which currently installs the include in exec-env/.
I have just submitted such a patch to remove the exec-env/ directory
both from installed and source hierarchy:
	https://patches.dpdk.org/patch/52031/
Please rebase on top of my patch and move rte_os.h one level upper.
Thanks

Please write Windows with first letter uppercase.
In this file, the comments looks superfluous and can be removed.
Or you can replace by something like "There is no strdup in Microsoft libc."

Please write Windows with first letter uppercase.
In this file, the comments looks superfluous and can be removed.
Or you can replace by something like "There is no strdup in Microsoft libc."

Adding the change to v8 along with a change in 
mk/target/<os>/rte.vars.mk to include path 'librte_eal/<OS>/eal/include'

+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM* C compiler and MSVC* linker.
+The Meson* Build system is used to prepare the sources for compilation with the Ninja backend.
+
+\*Other names and brands may be claimed as the property of others.
+
+Install the Compiler
+--------------------
+
+Download and install the clang compiler from `LLVM* website <http://releases.llvm.org/download.html>`_.
+For example, Clang-LLVM direct download link::
+
+	http://releases.llvm.org/7.0.1/LLVM-7.0.1-win64.exe
+
+
+Install the Linker
+------------------
+
+Download and install the Build Tools for Visual Studio to link and build the files on windows, from `Microsoft* website <https://visualstudio.microsoft.com/downloads>`_.
+When installing build tools, select the "Visual C++ build tools" option and ensure the Windows SDK is selected.
+
+
+Install the Build System
+------------------------
+
+Download and install the build system from `Meson* website <http://mesonbuild.com/Getting-meson.html>`_.
+A good option to choose is the MSI installer for both meson and ninja together::
+
+	http://mesonbuild.com/Getting-meson.html#installing-meson-and-ninja-with-the-msi-installer%22
+
+Install the Backend
+-------------------
+
+If using Ninja, download and install the backend from `Ninja* website <https://ninja-build.org/>`_ or
+install along with the meson build system.
+
+Build the code
+--------------
+
+The build environment is setup to build the EAL and the helloworld example by
+default.
+
+Using the ninja backend
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk
+    meson build
+    cd build
+    ninja
+
+Run the helloworld example
+==========================
+
+Navigate to the build directory and run `dpdk-helloworld.exe`.
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk\build

+Introduction
+============
+
+This document contains instructions for installing and configuring the Data
+Plane Development Kit (DPDK) software. The document describes how to compile
+and run a DPDK application in a Windows* OS application environment, without
+going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source files
+compile. Support is being added in pieces so as to limit the overall scope
+of any individual patch series. The goal is to be able to run any DPDK
+application natively on Windows.

Please try to limit the line length.
We are supposed to not exceed 80-chars if possible.
The best is to wrap lines logically (as in code)

Thought of adding asterisk in front of names and brands

those are claimed from other websites/ organizations

for instance, MSFT, LLVM.

Usually, we do not consider such "legal text". It looks weird.

Usually, we do not consider such "legal text". It looks weird.

[dpdk-dev] [PATCH v7 8/8] build: meson changes to build on windows

[Anand Rawat]

Added meson workarounds to build helloworld on windows.
Windows currently only supports kvargs and eal libraries.
This change restricts the build flow to supported libraries
only.

Not sure this change deserves a copyright update :)

You could override deps for Windows only.

Other workarounds look reasonnable. Thanks

I am not sure either, basic principle that I am following
is if any file is touched with some code/logic the license
should be updated. Do correct me if I am wrong. I can make
the changes accordingly in the future releases.

[dpdk-dev] [PATCH v8 00/10] HelloWorld example for Windows

[Anand Rawat]

Includes Windows-specific EAL changes and meson changes
to build the code on Windows.

v8 Changes:
1. Fixed rte_os.h not found issue on linux and freebsd.
2. Updated make build system to include path for rte_os.h.
3. Fixed math lib error on linux.
4. Separated eal logic and build changes.

v7 Changes:
1. Fixed missing def issues on linux and freebsd.
2. Updated comments in header files to be more descriptive 

v6 Changes:
1. Introduced rte_os.h for esstential os specific macros and typedefs.
2. Fixed commit typos and 'new line required at eof' issues.

v5 Changes:
1. Reduced meson workrounds for Windows.
2. Updated documention to include details about buildtool options

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file
2. Moved disabling meson logic to sub directories

v3 Changes:
1. Separated meson workarounds from the essential code changes
2. Added support for kvargs
3. Updated meson for building DLL on Windows using DEF files
4. Fixed documentation for html links and linker dependency
5. Added comments for Windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'Windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for Windows branch

notes:
*This patch is based on https://patches.dpdk.org/patch/52031/
and it is required to cleanly apply patch 3/10

*patch 5/10 contains module definition files and meson changes
required to build shared libraries on windows. These may be removed
in the future releases to be generated from the existing .map files.

*patch 10/10 contains meson workarounds to build helloworld
on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result
lcore mask is currently not supported.

*kernel modules and documentation can not be built on windows 
currently and should not be enabled.

Anand Rawat (10):
  eal: eal stub to add windows support
  meson: required changes for windows
  eal: add new rte_os.h header to build system
  eal: update common headers to use rte_os.h
  build: add module definition file for windows
  eal: sys/queue.h implementation for windows
  eal: add headers for compatibility with windows
  eal: add minimum viable code for eal on windows
  doc: add documentation for windows
  build: meson changes to build on windows

[dpdk-dev] [PATCH v8 00/10] HelloWorld example for Windows

[Anand Rawat]

Includes Windows-specific EAL changes and meson changes
to build the code on Windows.

v8 Changes:
1. Fixed rte_os.h not found issue on linux and freebsd.
2. Updated make build system to include path for rte_os.h.
3. Fixed math lib error on linux.
4. Separated eal logic and build changes.

v7 Changes:
1. Fixed missing def issues on linux and freebsd.
2. Updated comments in header files to be more descriptive 

v6 Changes:
1. Introduced rte_os.h for esstential os specific macros and typedefs.
2. Fixed commit typos and 'new line required at eof' issues.

v5 Changes:
1. Reduced meson workrounds for Windows.
2. Updated documention to include details about buildtool options

v4 Changes:
1. Exposed more functions for eal DLL in the module definition file
2. Moved disabling meson logic to sub directories

v3 Changes:
1. Separated meson workarounds from the essential code changes
2. Added support for kvargs
3. Updated meson for building DLL on Windows using DEF files
4. Fixed documentation for html links and linker dependency
5. Added comments for Windows header and source files

v2 Changes:
1. Incorporated reviews from v1.
2. Fixed license period for updated files.
3. Renamed 'winapp' folder to 'Windows'.
4. Cleaned unneeded meson changes.
5. Fixed code style warnings. 
6. Added maintainers information for Windows branch

notes:
*This patch is based on https://patches.dpdk.org/patch/52031/
and it is required to cleanly apply patch 3/10

*patch 5/10 contains module definition files and meson changes
required to build shared libraries on windows. These may be removed
in the future releases to be generated from the existing .map files.

*patch 10/10 contains meson workarounds to build helloworld
on windows, which will later be a part of the draft repository

*command-line parsing is not a part of this version as a result
lcore mask is currently not supported.

*kernel modules and documentation can not be built on windows 
currently and should not be enabled.

Anand Rawat (10):
  eal: eal stub to add windows support
  meson: required changes for windows
  eal: add new rte_os.h header to build system
  eal: update common headers to use rte_os.h
  build: add module definition file for windows
  eal: sys/queue.h implementation for windows
  eal: add headers for compatibility with windows
  eal: add minimum viable code for eal on windows
  doc: add documentation for windows
  build: meson changes to build on windows

For info, kernel/windows/ is not listed in MAINTAINERS. Will add it.
If there is a different maintainer for the kernel part,
you may create a new section in MAINTAINERS file later.

After having worked on rte_kni_common.h which is only in Linux,
I think we should add rte_os.h in meson file of each OS:
	- lib/librte_eal/linux/eal/meson.build
	- lib/librte_eal/freebsd/eal/meson.build
	- lib/librte_eal/windows/eal/meson.build

I confirm:
"global_inc" is used in "includes" variable but not in "headers" variable,
so rte_os.h is not installed as other files in "headers".
We must fill "env_headers" which is pulled by:
	headers = common_headers + env_headers

I will fix it before merging in master if you agree.

Agreed, env_headers need to be updated for rte_os.h.
I have tested the same and will incorporating the changes in v9.

No need for a v9. Once it will be in master, new changes must be

rte_panic should be used only in applications, not in libraries.
The application can do something in case of DPDK failure.
Please remove all calls to rte_panic() during next weeks, thanks.

Ok, will try to incorporate in v9. Just curious, is this the major issue?

Calls to rte_panic() can be seen in linux/eal and freebsd/eal.

No, there is a misunderstanding.
I am merging v8 and I am asking for a new patch to remove these calls.

By the way, I am fixing patch 3, please check my comment on this patch.

Re: [dpdk-dev] [PATCH v8 08/10] eal: add minimum viable code for eal on windows

[Thomas Monjalon]

I think the change below is bad because it is exposing an internal
function in a header file which may be included by apps.
I know you are still looking for pthread integration solutions,
so we can discuss how to fix it later.

Note that there is already an EAL function to create normal threads:
	rte_ctrl_thread_create()
You may want a similar function for dataplane threads perhaps.

Yes, we can work on removing eal_thread_create and substituting it
with rte_ctrl_thread_create. We have been able to macro substitute
quite a lot of pthread lib functionality with Microsoft libc. I can 
start looking into porting those functionalities for 
rte_ctrl_thread_create() on Windows.

+
+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM C compiler
+and Microsoft MSVC linker.
+The Meson Build system is used to prepare the sources for compilation
+with the Ninja backend.
+The installation of these tools is covered in this section.
+
+
+Install the Compiler
+--------------------
+
+Download and install the clang compiler from
+`LLVM website <http://releases.llvm.org/download.html>`_.
+For example, Clang-LLVM direct download link::
+
+	http://releases.llvm.org/7.0.1/LLVM-7.0.1-win64.exe
+
+
+Install the Linker
+------------------
+
+Download and install the Build Tools for Visual Studio to link and build the
+files on windows,
+from `Microsoft website <https://visualstudio.microsoft.com/downloads>`_.
+When installing build tools, select the "Visual C++ build tools" option
+and ensure the Windows SDK is selected.
+
+
+Install the Build System
+------------------------
+
+Download and install the build system from
+`Meson website <http://mesonbuild.com/Getting-meson.html>`_.
+A good option to choose is the MSI installer for both meson and ninja together::
+
+	http://mesonbuild.com/Getting-meson.html#installing-meson-and-ninja-with-the-msi-installer%22
+
+Install the Backend
+-------------------
+
+If using Ninja, download and install the backend from
+`Ninja website <https://ninja-build.org/>`_ or
+install along with the meson build system.
+
+Build the code
+--------------
+
+The build environment is setup to build the EAL and the helloworld example by
+default.
+
+Using the ninja backend
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk
+    meson build
+    cd build
+    ninja
+
+Run the helloworld example
+==========================
+
+Navigate to the build directory and run `dpdk-helloworld.exe`.
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk\build
+    helloworld.exe

+Introduction
+============
+
+This document contains instructions for installing and configuring the Data
+Plane Development Kit (DPDK) software. The document describes how to compile
+and run a DPDK application in a Windows* OS application environment, without
+going deeply into detail.
+
+\*Other names and brands may be claimed as the property of others.
+
+Limitations
+===========
+
+DPDK for Windows is currently a work in progress. Not all DPDK source files
+compile. Support is being added in pieces so as to limit the overall scope
+of any individual patch series. The goal is to be able to run any DPDK
+application natively on Windows.

+
+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+The DPDK and its applications require the Clang-LLVM C compiler
+and Microsoft MSVC linker.
+The Meson Build system is used to prepare the sources for compilation
+with the Ninja backend.
+The installation of these tools is covered in this section.
+
+
+Install the Compiler
+--------------------
+
+Download and install the clang compiler from
+`LLVM website <http://releases.llvm.org/download.html>`_.
+For example, Clang-LLVM direct download link::
+
+	http://releases.llvm.org/7.0.1/LLVM-7.0.1-win64.exe
+
+
+Install the Linker
+------------------
+
+Download and install the Build Tools for Visual Studio to link and build the
+files on windows,
+from `Microsoft website <https://visualstudio.microsoft.com/downloads>`_.
+When installing build tools, select the "Visual C++ build tools" option
+and ensure the Windows SDK is selected.
+
+
+Install the Build System
+------------------------
+
+Download and install the build system from
+`Meson website <http://mesonbuild.com/Getting-meson.html>`_.
+A good option to choose is the MSI installer for both meson and ninja together::
+
+	http://mesonbuild.com/Getting-meson.html#installing-meson-and-ninja-with-the-msi-installer%22
+
+Install the Backend
+-------------------
+
+If using Ninja, download and install the backend from
+`Ninja website <https://ninja-build.org/>`_ or
+install along with the meson build system.
+
+Build the code
+--------------
+
+The build environment is setup to build the EAL and the helloworld example by
+default.
+
+Using the ninja backend
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk
+    meson build
+    cd build
+    ninja
+
+Run the helloworld example
+==========================
+
+Navigate to the build directory and run `dpdk-helloworld.exe`.
+
+.. code-block:: console
+
+    cd C:\Users\me\dpdk\build
+    helloworld.exe
+    hello from core 1
+    hello from core 3
+    hello from core 0

This is not what I call keeping build intact for Linux/BSD :)

I did not catch it before because test-meson-builds.sh is not testing
compilation of the examples with meson. Bruce, may we add it?

I will add back the original deps line in master branch.

That is correct,
deps = ['eal', 'mempool', 'net', 'mbuf', 'ethdev', 'cmdline']
should have not been removed from this file. Please add the line
