This patchset adds support for testing a number of examples using the
DPDK pkgconfig file, allowing us to check that the file works. It also
includes some more general cleanups for the examples, including adding
support for building from pkg-config to a couple of examples which were
missing that.

This patchset includes some work that was previously discussed on-list:
https://mails.dpdk.org/archives/dev/2019-April/131041.html

Bruce Richardson (6):
  examples: remove auto-generation of examples list
  examples: add support for relocated DPDK install
  devtools/test-meson-builds: remove dependency on clang
  devtools/test-meson-builds: add testing of pkg-config file
  examples/vdpa: support building from pkg-config info
  examples/vhost_crypto: support building from pkg-config info

The examples/meson.build file scanned the filesystem to find all examples
to build (for examples=all option) and install. However, using run_command
and scanning the filesystem prevented ninja from properly detecting the
addition or removal of any examples - one had to recreate the build
directory from scratch to guarantee correct detection of all examples. This
patch replaces this generated list with a static list of examples, thereby
allowing proper tracking by ninja/meson, but at the cost of having to
update this file when a new example is added or removed.

For testing of DPDK, we want to override the prefix given by the
pkg-config file, so that we can get correct paths for DPDK installed
in an unusual location.

From: Bruce Richardson @ 2019-05-03 13:35 UTC (permalink / raw)
  To: dev; +Cc: Bruce Richardson

For testing of DPDK, we want to override the prefix given by the
pkg-config file, so that we can get correct paths for DPDK installed
in an unusual location.

Allow the script to run with a reduced set of builds if clang, or
other compilers, are missing.

The pkg-config file generated as part of the build of DPDK should allow
applications to be built with an installed DPDK. We can test this as
part of the build by doing an install of DPDK to a temporary directory
within the build folder, and by then compiling up a few sample apps
using make working off that directory.

Hi,

Would using "--define-prefix" allow to avoid the special-sauced
DPDK_PC_PREFIX variable?

Perhaps I'm missing something, but I'm not seeing how, since the code above
is already using the --define-variable flag. Swapping one pkg-config flag
for another isn't likely to change the flow. Whatever way things work, we
need an environment variable to pull in the path change. Since one doesn't
seem to be available for pkg-config directly, we need a DPDK special-sauced
one.

Perhaps I'm missing something, but I'm not seeing how, since the code above
is already using the --define-variable flag. Swapping one pkg-config flag
for another isn't likely to change the flow. Whatever way things work, we
need an environment variable to pull in the path change. Since one doesn't
seem to be available for pkg-config directly, we need a DPDK special-sauced
one.

I think PKG_CONFIG_PATH is a more common and more well-understood flag
to use - using define-prefix should allow to use that instead

Yes, except pkg-config-path only gives the path to the pkg-config file, it
doesn't affect the prefixes in the file itself, and it's the latter we need
to modify.

Using --define-prefix will automatically adjust the prefixes based on
the path:

Using --define-prefix will automatically adjust the prefixes based on
the path:

A small set of fixes for building examples, that was previously part of
the larger set, but pulled out separately for easier apply.

Bruce Richardson (3):
  examples: fix install of sample apps if setting not provided
  examples: remove auto-generation of examples list
  examples: fix make clean when using pkg-config for building

While the examples were being installed into the appropriate install path
when processing the examples/meson.build file, that file was only processed
if the "examples" meson parameter was non-empty. Since we now do more than
just build the examples, we need to unconditionally process the file.

Fixes: 2daf565f91b5 ("examples: install as part of ninja install")

The examples/meson.build file scanned the filesystem to find all examples
to build (for examples=all option) and install. However, using run_command
and scanning the filesystem prevented ninja from properly detecting the
addition or removal of any examples - one had to recreate the build
directory from scratch to guarantee correct detection of all examples. This
patch replaces this generated list with a static list of examples, thereby
allowing proper tracking by ninja/meson, but at the cost of having to
update this file when a new example is added or removed.

This also fixes an issue with Windows builds, since "sh" is not available
there.

Fixes: 2daf565f91b5 ("examples: install as part of ninja install")

The "make clean" command had a number of issues:
- the "--ignore-fail-on-non-empty" flag is not present on BSD
- the call to remove the build folder would fail if there was no build
  folder present.

These are fixed by only removing the build folder if it exists, and by
using -p flag to rmdir in place of --ignore-fail-on-non-empty

Fixes: 22119c4591a0 ("examples: use pkg-config in makefiles")

  To: dev; +Cc: bluca, Bruce Richardson

This patchset adds support for testing a number of examples using the
DPDK pkgconfig file, allowing us to check that the file works. It also
includes some more general cleanups for the examples, including adding
support for building from pkg-config to a couple of examples which were
missing that.

V2: separated out a few bug-fixes into a separate set from this one
    changed to use --define-prefix flag for pkgconfig rather than a
    custom environment variable.

Bruce Richardson (5):
  examples: add support for relocated DPDK install
  devtools/test-meson-builds: remove dependency on clang
  devtools/test-meson-builds: add testing of pkg-config file
  examples/vdpa: support building from pkg-config info
  examples/vhost_crypto: support building from pkg-config info

For testing of DPDK, we want to override the prefix given by the
pkg-config file, so that we can get correct paths for DPDK installed
in an unusual location.

Allow the script to run with a reduced set of builds if clang, or
other compilers, are missing.

The pkg-config file generated as part of the build of DPDK should allow
applications to be built with an installed DPDK. We can test this as
part of the build by doing an install of DPDK to a temporary directory
within the build folder, and by then compiling up a few sample apps
using make working off that directory.

The vdpa example app did not check for a libdpdk pkg-config file and
attempt to build using that. Add support for that method of compile to
align the app with the other examples.

The vhost_crypto example app did not check for a libdpdk pkg-config file
and attempt to build using that. Add support for that method of compile to
align the app with the other examples.

Self-nak, sorry. Need to take account of an empty "examples" value inside
examples/meson.build.

V3 to follow soon. :-(

A small set of fixes for building examples, that was previously part of
the larger set, but pulled out separately for easier apply.

V3: changed patch 1, to properly quit processing examples/meson.build
    if the examples list was empty.

Bruce Richardson (3):
  examples: fix install of sample apps if setting not provided
  examples: remove auto-generation of examples list
  examples: fix make clean when using pkg-config for building

While the examples were being installed into the appropriate install path
when processing the examples/meson.build file, that file was only processed
if the "examples" meson parameter was non-empty. Since we now do more than
just build the examples, we need to unconditionally process the file.

The examples/meson.build file scanned the filesystem to find all examples
to build (for examples=all option) and install. However, using run_command
and scanning the filesystem prevented ninja from properly detecting the
addition or removal of any examples - one had to recreate the build
directory from scratch to guarantee correct detection of all examples. This
patch replaces this generated list with a static list of examples, thereby
allowing proper tracking by ninja/meson, but at the cost of having to
update this file when a new example is added or removed.

This also fixes an issue with Windows builds, since "sh" is not available
there.

The "make clean" command had a number of issues:
- the "--ignore-fail-on-non-empty" flag is not present on BSD
- the call to remove the build folder would fail if there was no build
  folder present.

These are fixed by only removing the build folder if it exists, and by
using -p flag to rmdir in place of --ignore-fail-on-non-empty

Fixes: 22119c4591a0 ("examples: use pkg-config in makefiles")

I see an issue with the experimental tag:

It seems "CFLAGS += -DALLOW_EXPERIMENTAL_API"

Better to use the real directory name as prerequisite,
instead of "build".

No, it's not, it's reset by the call to the DPDK make build system in
the other leg of the code. I'll fix this in the Makefile in v3.

Not sure what you mean here, build is the name of the directory. [This is
also consistent with what is done in all the other example makefiles. If it
needs updating, then it should be done as a general patch to all examples
in 19.11 release timeframe.]

This patchset adds support for testing a number of examples using the
DPDK pkgconfig file, allowing us to check that the file works. It also
includes some more general cleanups for the examples, including adding
support for building from pkg-config to a couple of examples which were
missing that.

V3:
 * fix missing -DUSE_EXPERIMENTAL_API cflag when building using "make
   examples"

V2:
 * separated out a few bug-fixes into a separate set from this one
 * changed to use --define-prefix flag for pkgconfig rather than a
   custom environment variable.

For testing of DPDK, we want to override the prefix given by the
pkg-config file, so that we can get correct paths for DPDK installed
in an unusual location.

Allow the script to run with a reduced set of builds if clang, or
other compilers, are missing.

The pkg-config file generated as part of the build of DPDK should allow
applications to be built with an installed DPDK. We can test this as
part of the build by doing an install of DPDK to a temporary directory
within the build folder, and by then compiling up a few sample apps
using make working off that directory.

The vdpa example app did not check for a libdpdk pkg-config file and
attempt to build using that. Add support for that method of compile to
align the app with the other examples.
