[Buildroot] [PATCH v3 2/3] package/waffle: new package

[Romain Naour]

waffle has four "backends", each having their own dependencies.
At least one "backend" must be enabled, otherwise Waffle will refuse to
build. The "backends" are:

 - glx, which needs full OpenGL + x11-xcb
 - wayland, which needs wayland-client, wayland-egl and EGL
 - x11-egl, which needs x11-xcb and EGL
 - gbm, which needs gbm, libudev and EGL

Backport an upstream patch fixing a build issue with musl toolchains.
Add a new patch fixing build with Wayand without X11.

+Subject: [PATCH] third_party/threads: Use PTHREAD_MUTEX_RECURSIVE by default
+
+PTHREAD_MUTEX_RECURSIVE_NP was used for compatibility with old glibc.
+Although due to the_GNU_SOURCES define the portable,
+PTHREAD_MUTEX_RECURSIVE will be available for Linuxes since at least
+1998. Simplify things giving us compatibility with musl which
+apparently does not provide the non-portable define.
+
+Inspired by almost identical commit in mesa aead7fe2e2b(c11/threads: Use
+PTHREAD_MUTEX_RECURSIVE by default) by Felix Janda.

+Subject: [PATCH] cmake: forward cflags from *.pc files to waffle cflags
+
+When building mesa egl without x11 and gles2 the headers need a
+MESA_EGL_NO_X11_HEADERS define to avoid including X11 headers.
+
+This define MESA_EGL_NO_X11_HEADERS  is lost while building waffle
+since CGLAGS defined by pc files are not used.
+
+MESA_EGL_NO_X11_HEADERS is defined in CFLAGS from egl.pc.

+	  Waffle is a cross-platform library that allows one to defer

[Buildroot] [PATCH v3 3/3] package/piglit: new package

[Romain Naour]

Piglit is an open-source test suite for OpenGL implementations.
It's an python3 script based around several tools like glxinfo,
wflinfo, dmesg.

Even though waffle support can be replaced by freeglut,
using pliglit with waffle is recommended since freeglut
will be replaced by waffle.

v3: bump version, rebase after the switch to xorgproto
    add a dependency on waffle package
    reorder packages in Config.in
    I'm not sure if we can avoid host-python-{mako,numpy,six} dependency
    because the build system is checking with host-python.
    Yocto packaging use the same workaround.

Are you sure that GLES support *must* be available ?

This seems very weird, because in a typical "desktop" context, with
X.org and GLX, you have full OpenGL support, but you don't have GLES
libraries available.

Is this dependency coming from actual runtime issues you have
encountered ? Could you explain it in a bit more details ?

I dropped the dependency on libgles, since there is no such build
requirement in waffle. And then applied to master, thanks!

[Buildroot] [PATCH v3 3/3] package/piglit: new package

[Romain Naour]

Hi,

Ping.

The first version of this patch was sent one year ago:
http://patchwork.ozlabs.org/patch/852832/

If someone can take a look, it would be great.

Best regards,
Romain
