Thanks for the suggestion. I applied the patch to meson and the OPT 
error is gone and it now compiles.

Thanks!

Please add '-v' flag to Meson invocation and post the output as plain text.
The exact commands you're using will also help.

> Program cat found: YES (C:\MinGW\msys\1.0\bin\cat.EXE)

I suspect MSYS confuses Meson and it may call 'clang.exe' instead of
'clang-cl.exe'. Try excluding MSYS from your PATH.

Hi Dmitry,

Thanks for your help. "meson -v" only shows meson's version.
Am I doing it wrong?

It'm my mistake, pardon me. Ninja has '-v' option, Meson doesn't.

Hi Dmitry,

Thanks!
I uninstalled my Visual Studio 2017, and use 2019.
The problem disappeared, but now I hit Jeremy's issue
https://github.com/mesonbuild/meson/pull/6483

From the step in
https://mesonbuild.com/Quick-guide.html#installation-from-source
I tried to compile meson by doing:
$ git clone  https://github.com/mesonbuild/meson.git
$ cd meson
$ meson builddir
 ERROR: Neither directory contains a build file meson.build.

How do I generate a meson.build file?

Thanks
William

I build Meson from Windows command line (not Git Bash) as pip package:

C:\src\meson> python setup.py install --user

You need write permissions for C:\Python, so use elevated command prompt or
an administrator account. To use the new version, make sure C:\Python\Scripts
is in the beginning of your PATH (assuming C:\Python being your Python 3
installation directory).

Don't forget to apply the patch, it's not in upstream yet. You can instead
clone the fork directly:

git clone -b msvc-linker-arg-prefix https://github.com/PlushBeaver/meson.git

Hi Dmitry,

now with "ninja -v", I got another error saying:

Those are not errors, just harmless warnings. You can now build and run an
example program (rerun meson with -Dexamples=helloworld per Windows Getting
Started Guide).

No, you shouldn't have to, if you're building "master" branch of "dpdk"
repository (https://git.dpdk.org/dpdk/). I noticed your working copy is named
"dpdk-draft-windows", are you trying to build from that repo instead
(https://git.dpdk.org/draft/dpdk-draft-windows/)? If so, its build system
only supports Windows via MSBuild and ICC, according to that repo docs. To
build current DPDK on Windows, you should be using "dpdk" repo.

Hi  Dmitry,

Thanks for the information. Now I switch to dpdk repo and it works!

Wonderful, thanks Dmitry for the patch in meson.

Please would you like to add a note with a link to the patch in the DPDK doc?

[dpdk-dev] DPDK Windows Build

[Jeremy Plsek]

[-- Attachment #1: Type: text/plain, Size: 399 bytes --]

Hello,

I'm trying to build DPDK on Windows for the DPDK Community Lab CI.

I have a mostly fresh install of Windows Server 2019 and I mostly
followed https://doc.dpdk.org/guides/windows_gsg/build_dpdk.html

But I'm having trouble compiling it.

I've attached logs for both clang 7 and clang 9.

Any help or suggestions would be appreciated.

Thanks

Re: [dpdk-dev] DPDK Windows Build

[Dmitry Kozliuk]

Hello Jeremy,

> clang: error: no such file or directory: '/OPT:REF'

There is a bug in Meson: '/OPT:REF' must be prefixed with '-Wl,' when using
Clang with link.exe, because Clang does not recognize '/OPT:REF' as an
argument to pass to linker, but treats it as a filename instead.
A patch is not under review: https://github.com/mesonbuild/meson/pull/6483
I was able to successfully build DPDK after applying this patch to Meson.
