[mythtv-users] 0.27 configure script does not recognize OpenGL

[Dan Littlejohn]

I also have Gentoo and found that I have the same problem with opengl not
configuring when building Mythtv.  Here is what I tried and found.

I checked that the kernel options per this wiki.

https://wiki.gentoo.org/wiki/Xorg/Hardware_3D_acceleration_guide

I re-installed mesa and nvidia-drivers.

I checked and do have GL/gl.h

glxgears does run.  However, when I do glxinfo | grep rendering it shows my
direct rendering : No and glxinfo | grep -i opengl does not have the core
profile lines like in this discussion

https://forums.gentoo.org/viewtopic-t-954908-start-0.html

So I suspect this to be a problem system wide and not with the Mythtv
configure script.  Still I have not quite tracked down what is wrong with
the direct renderer and any help would be appreciated to what might sort
this out.  I am hoping this will fix the opengl configure problem with
Mythtv
