can you include GLES2/gl2.h and GL/gl.h at the same time?
mesa 1.8 rc4 on Ubuntu Bionic
I was just chatting with gstreamer upstream about a build failure we/they are
seeing, where we can't build gst-plugins-good on arm. Excerpt from
<a href="https://buildd.debian.org/status/fetch.php?pkg=gst-plugins-good1.0&arch=armhf&ver=1.13.1-1&stamp=1519744588&raw=0">https://buildd.debian.org/status/fetch.php?pkg=gst-plugins-good1.0&arch=armhf&ver=1.13.1-1&stamp=1519744588&raw=0</a>:

The problem is that Qt is built with GLES on arm - it ends up including gl31.h
which can't be included together with glext.h that gstreamer brings in.
However, this *does* work on amd64. I'm attaching a .c file extracted from
gstreamer's build system that tests if you can include <GLES2/gl2.h> and
<GL/gl.h> at the same time. This compiles fine on amd64/arm64/ppc64el for me,
but not i386/armhf.
Is this supposed to work or is it an accident that you can do it on 64 bit?</pre>
