--- Comment #5 from Emil Velikov <emil.l.veli...@gmail.com> --- (In reply to George Diamantopoulos from comment #4) > Created attachment 117106 [details] [review] > Fix build against EGL implementations that don't support the > EGL_MESA_screen_surface extension > > There is a patch by Frank Binns (posted on mesa-dev) since 2012 on this... > It worked for me, so I'm attaching it here While this should work and has been the approach used so far in mesa-demos, I'm having second doubts how wise of an idea it is. In this particular example, this will result in a "empty" demo/program which won't do anything when run on a EGL_MESA_screen_surface capable driver. I.e. even if your system is perfectly fine, the binary build by your distro/elsewhere with the missing definition will be useless. May I suggest that we add the relevant defines, after including the *GL headers. This way the binary will work on compatible systems, and (should) bail out if the extension is not supported. One could also fix the other similar cases, while at it ;-) Git grep shows some ~120 lines :-P -- You are receiving this mail because: You are the QA Contact for the bug.
