Changes v1 -> v2:
  - new patch

Changes v2 -> v3:
  - check source tar file signature (thanks for the help of
    Baruch Siach and Eric Le Bihan)
  - add comment about patch removable

  To: buildroot

Add FOO_MESON_CFLAGS, FOO_MESON_LDFLAGS and FOO_MESON_CXXFLAGS
variables to allow per package additional flags.

Change to buildtype plain as all compiler/linker flags forcing
debug/release are already given via the cross-compilation.conf
file.

Signed-off-by: Peter Seiderer <ps.report@gmx.net>
---
Notes:
  - documentation change for new flags missing
  - use in pkg-meson.mk the same sed/printf for flags quotation mark
    and comma adding

Changes v1 -> v2:
  - no changes

Changes v2 -> v3:
  - no changes

- remove legacy patch
  0003-configure-Makefile.am-use-pkg-config-to-discover-lib.patch

- add patch to fix meson atomic ops detection
  0003-meson.build-fix-intel-atomics-detection.patch

- add patch to enable static build
  0004-meson.build-enable-static-build.patch

Signed-off-by: Peter Seiderer <ps.report@gmx.net>

Notes:
  - convertion from "LIBDRM_CONF_ENV = ac_cv_prog_cc_c99='-std=gnu99'"
    is missing (maybe meson gets it right (?) or use LIBDRM_MESON_CFLAGS
    to force it)

Changes v1 -> v2:
  - add 0003-meson.build-fix-intel-atomics-detection.patch to fix
    sparc compile

Changes v2 -> v3:
  - fix 0003-meson.build-fix-intel-atomics-detection.patch (linking
    needs main)
  - add 0004-meson.build-enable-static-build.patch to enable static
    compile

-Subject: [PATCH] configure/Makefile.am: use pkg-config to discover
- libatomic_ops
-
-The configure script currently tests the availability of libatomic_ops
-by checking the presence of atomic_ops.h. While this is good enough as
-an availability test, it is not sufficient as on some platforms,
-libatomic_ops provides an actual shared library against which we
-should be linked to access libatomic_ops functionality.
-
-Therefore, we instead use PKG_CHECK_MODULES() to test the availability
-of libatomic_ops. Besides testing its availability, this also fills in
-the ATOMIC_OPS_LIBS variable with the list of libraries we need to
-link with to use libatomic_ops.
-
-All Mesa drivers that include xf86atomic.h have been updated to link
-against ATOMIC_OPS_LIBS.
-
-Of course, if we're not using libatomic_ops, ATOMIC_OPS_LIBS is empty,
-and we don't link against it.

+Subject: [PATCH] meson.build: fix intel atomics detection
+
+Use the stronger compiler.link() test (instead of the weaker
+compiler.compile()) to fix the intel atomics detection.
+
+Fixes false positive in case of sparc compile (buildroot toolchain).
+
+Upstream suggested: https://lists.freedesktop.org/archives/dri-devel/2018-July/183885.html

For details since 1.8.x see [1], [2] and [3].

Build system changed from autotools to meson exclusively
since 1.9.0 (see [1]).

Add hash for license file.

I am not super happy with this approach, because this file is not meant
to be used just during the build of Buildroot packages, but potentially
after the Buildroot build is finished, for people to easily
cross-compile Meson-based software manually. To me, this file is
similar to toolchainfile.cmake that pkg-cmake.mk is installing, and
which allows to easily cross-compile stuff with CMake outside of
Buildroot, using the Buildroot generated toolchain.

So I would prefer to:

 - Move this file to
   $(HOST_DIR)/usr/share/buildroot/meson-cross-compilation.conf or
   something like that, so that we are a bit consistent with what we do
   for CMake.

 - Keep it directly usable.

 - Pass the additional CFLAGS/LDFLAGS to packages on the command line
   rather than through this file.
   https://mesonbuild.com/howtox.html#set-extra-compiler-and-linker-flags-from-the-outside-when-eg-building-distro-packages
   seems to say this is possible, no ? Or does it override the ones
   from the cross-compilation.conf ?

Thanks!

Thomas

The CFLAGS are ignored, e.g. with 'LIBDRM_CONF_ENV += CFLAGS=-DAO_NO_SPARC_V9' in package/libdrm/libdrm.mk:

	$ make libdrm V=1

What if you _also_ pass them in LIBDRM_NINJA_ENV ?

Hello,

It seems weird, no? It is documented to be working, and even at runtime
it tells you "I am going to use those additional CFLAGS". Isn't this a
bug or a misuse of meson from us ?

I would really prefer to understand what is going on here instead of
having to generate per-package .conf files.

Thanks!

Bug or feature of the cross-compilation.conf usage? Will take a look at
the meson sources....

Seems to be intentional, see mesonbuild/backend/backends.py#L542 ([1]):

        if not target.is_cross:
            # Compile args added from the env: CFLAGS/CXXFLAGS, etc. We want these
            # to override all the defaults, but not the per-target compile args.
commands += self.environment.coredata.get_external_args(compiler.get_language())

With the 'if not target.is_cross' added with this commit [2] fixing [3] which
suggests adding CROSS_*FLAGS...

Regards,
Peter

Meh. This is plain silly, and completely inconsistent with what all
other build systems do. The idea that CFLAGS should not be taken into
account when cross-compiling is really stupid, as is "Cross build
settings should come from the cross file and nowhere else".

But well, OK, let's go with your solution then. I would still like a
proper .conf file to be generated and move in usr/share/buildroot/,
like the CMake file.

Could you also complain in that bug report, to explain that really
CFLAGS should be supported ?

Thanks for the additional research!

Sorry for the slow answer. Turns out that in the mean time, another
libinput bump was merged which converted the package to use the meson
build system.

So I marked your patch as Superseded in patchwork.

Best regards,

Thomas

It's been a while: could you refresh this patch on the latest master
and send a new version ?

Thanks,
