[Buildroot] Failed to build libexoxy with nvidia-driver

[Alexandre Maumené]

Hi,

I'm trying to build libepoxy with nvidia-driver but it fails with this
error:

checking for EGL... no
configure: error: Package requirements (egl) were not met:

Package egl was not found in the pkg-config search path.
Perhaps you should add the directory containing `egl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'egl', required by 'world', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables EGL_CFLAGS
and EGL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

I'm new to buildroot and I don't know much about Nvidia binary drivers.
Any help will be more than welcome.

Regards,

 Indeed, nvidia-driver selects BR2_PACKAGE_HAS_LIBEGL but doesn't install egl.pc
(it does install gl.pc). And there's also no glesv2.pc. J?r?me, Yann, could you
look into it?

 Perhaps we should add a check in the lib*gl* virtual packages that they install
a .pc file...

[Buildroot] Failed to build libexoxy with nvidia-driver

[Alexandre Maumené]

Hi,

I've copied the egl.pc from
package/nvidia-tegra23/nvidia-tegra23-binaries/egl.pc to
package/nvidia-driver and added this line $(INSTALL) -D -m 0644
package/nvidia-driver/egl.pc $(STAGING_DIR)/usr/lib/pkgconfig/egl.pc to
package/nvidia-driver/nvidia-drive.mk and it seems to compile fine now.

Thanks for your help :)

I see Alexandre already reported sucess and explained the hack he did.
I'll look into submiting a proper patch soonish.

Gut feelings only, but no. It is perfectly legit to be a provider of EGL
(or whatever other GL stuff) and not provide a .pc file with that.

However, I can see the benefit for consistency. But then, it puts some
burden on the packager which upstream do not provide a .pc file, to
write their own... :-/

Not having a .pc file for EGL/OpenGLES, etc. will break lots and lots
of packages. So I think it is a good idea to force people submitting
OpenGL implementations to make sure a .pc file is installed.
