[Bug 1811678] Re: Inconsistent OpenGL support across architectures

[Dmitry Shachnev]

Sorry for the delay, for some reason I have not received a mail about
this bug.

Starting with Ubuntu 19.04 release, there is no difference between
Debian and Ubuntu: both use OpenGL ES on armel/armhf, and desktop OpenGL
on the other architectures. Initially I wanted to add arm64 to that list
too, but after the discussion in https://lists.debian.org/debian-
devel/2018/11/msg00457.html the plan was changed.

The reason for using OpenGL ES on armel/armhf is that the majority of
devices with that architecture are mobile devices that have video chips
supporting only OpenGL ES natively.

It looks like v4l-utils currently builds fine on all supported Ubuntu
releases, but if you have problems with supporting OpenGL ES versions,
please let me know.

** Changed in: qtbase-opensource-src (Ubuntu)
   Status: New => Fix Released

[Bug 1811678] Re: Inconsistent OpenGL support across architectures

[Gregor Jasny via ubuntu-bugs]

I guess this is due to the following lines in debian/rules:

gles2_architectures := armel armhf arm64
ifeq ($(DEB_HOST_ARCH),$(findstring $(DEB_HOST_ARCH), $(gles2_architectures)))
extra_configure_opts += -opengl es2
else
extra_configure_opts += -opengl desktop
endif

Still my question is why those architectures (should) differ from the
regular ones. And why Ubuntu is behaving differently than Debian.

In my case I need access to qopenglext.h contents which does not get
loaded if OpenGL ES2 support is present.
