@x11, is GLES2 not supported on 32-bit systems, or is that a problem with our setup?

Yes, GLES2 is supported on 32-bit systems.

[Comment 5 Michał Górny 2014-10-20 21:33:36 UTC]

So the difference is:

  checking whether it is possible to include both GL and GLES2 headers... no
  configure: WARNING: Disabling GL|ES 2.0 support

in x86 run. Would be nice if someone with native x86 could confirm whether it is x86- or multilib-specific.

And the specific bits from config.log:

Long story short, the two header files use conflicting types for the same typedefs...

[Comment 7 Mart Raudsepp 2014-10-21 07:47:41 UTC]

I ported over my gl related changes from my overlay, which I forgot when bringing this over.
I am quite sure the problem persist (but behind a USE=gles2 flag), but it should be more correct ebuild now for testing. Missing various REQUIRED_USE in combination with USE=egl though (probably egl? ( || opengl egl ) or something along those lines).

The version I will introduce to the tree will completely disable glimagesink and co until we figure this stuff out...

[Comment 8 Michał Górny 2014-10-21 11:56:32 UTC]

Now that leio has fixed the automagic selection of GL extensions and USE=gles2 controls GLES2 support we no longer have the header mismatch. Now the package correctly fails to compile :).

As I see it, we have two options now:

1. if upstream doesn't support mixing egl & gles2, we should probably add unconditional REQUIRED_USE'^^ ( egl gles2 )'

2. if upstream supports mixing the two, they should probably fix the bugs. In meantime, we can add REQUIRED_USE='abi_x86_32? ( ^^ ( egl gles2 ) )' and likes for the necessary arches.

[Comment 10 Michał Górny 2014-10-21 14:14:42 UTC]

Oh, and this is no longer a multilib issue :).

[Comment 11 Pacho Ramos 2015-02-03 20:35:17 UTC]

Can you please recheck with 1.4.5 in the tree to see if we can improve/fix anything more?

Thanks

[Comment 12 Mart Raudsepp 2015-02-04 05:59:35 UTC]

gles2 without egl makes zero sense. You can't instantiate gles2 without EGL, I don't think...

[Comment 13 Mart Raudsepp 2015-02-04 06:01:48 UTC]

Ok, Matt says you can via GLX_EXT_create_context_es2_profile but likely no such thing on platforms where GLES2 instead of GL is preferred (or rather GL does not exist in the first place). Also no GLX* on Wayland.

[Comment 14 Andrei Slavoiu 2015-02-04 21:33:23 UTC]

Guys, this is wrong, there is no problem with using both egl and gles2, the problem is with gles2 and opengl on 32bit.

Like the config log states it's not possible to include both GL and GLES2 headers on x86, but unlike the warning message "configure: WARNING: Disabling Desktop GL support" GL is not actually being disabled. This is why the compile phase will end up including both headers and fail.

USE="egl gles2 -abi_x86_32" or USE="egl gles2 -opengl" will also make the build succeed. So the restriction should be more like "you can't enable gles2, opengl and abi_x86_32 at the same time".

gst-plugins-bad-1.4.5-fix-both-opengl-gles2.patch

Found the problem in configure.ac: the "X, GLX and OpenGL" block would set USE_OPENGL based on the value of HAVE_GL before the "check if we can include both GL and GLES2 at the same time" block is executed and sets HAVE_GL to false.

There would be 2 ways of fixing this: change the order of the blocks or set USE_OPENGL to false in the second block as well. But I found an even more interesting thing: the "check if we can include both GL and GLES2 at the same time" block contains a typo, it checks for NEED_OPENGL instead of NEED_GL and whe fixing that configure will fail with "error: Cannot seem to include both GL and GLES2 headers. Try disabling one API".

I actually liked the auto-fallback to disabling Desktop OpenGL when both can't be used, but apparently that is not what the devs intended to happen when both APIs are explicitly requested.

[Comment 16 Andrei Slavoiu 2015-02-04 23:28:19 UTC]

Submitted this upstream, 
https://bugzilla.gnome.org/show_bug.cgi?id=744020

I guess for Gentoo it's not needed to include the patch as it will only change the error message when building with the wrong USE flags. All it's required is to replace the current USE depends.

[Comment 17 Pacho Ramos 2015-02-05 08:42:36 UTC]

(In reply to Andrei Slavoiu from comment #14)
> "you can't enable
> gles2, opengl and abi_x86_32 at the same time".

Does it make sense to allow gles2 and opengl at the same time on abi_x86_64 too or we can disallow gles2+opengl on all setups? 

Thanks

Can we please remove the gles2 <-> egl blocker then?
