Description Carlos Alberto Lopez Perez 2018-05-14 18:57:44 PDT
Trying to build WPE (upstream) with RPi userland drivers and gstreamer-gl currently results in a build failure due to some mismatches on the definitions of the GLsync types.

The issue seems to be the following one:

 1. RPi userland drivers doesn't define GLsync in the GLESv2 headers
 2. Therefore gstreamer-plugins-bad define "GST_GL_HAVE_GLSYNC 0" at configure time
 3. libepoxy enables GLsync in its headers
 4. In WPE in MediaPlayerPrivateGStreamerBase.cpp we include first the libepoxy headers before the gstreamer-gl ones
 5. gstreamer-gl headers try to give a type definition to GLsync (due to 2.) but it conflicts with the one already assigned from libepoxy (3. and .4)
 6. Build error happens

This issue seems to be already workarounded in the wpewebkit-downstream repository. We should fix this upstream as well.

There seem to be more types conflicting, which cause build errors like this:

It seems this can be avoiding by defining __gl2_h_ before including the gst gl headers, to ensure the definitions/types from libepoxy are used.

What's the GStreamer version you're compiling? I don't think this happens with newer ones.

Can you try with 1.14 then? 1.12.2 is a bit old :)

Tried. I can't reproduce with 1.14

However, I'm still interested in fixing this issue with 1.12 (which will be a supported version for us for a long time)

I will try to add a version check to the patch.
