MythTV 0.27 ebuild does not recognize OpenGL and so I cannot use the OpenGL menu painter anymore. I am using the nvidia binary driver and eselect says that nvidia OpenGL is active. glxinfo also says that OpenGL (Direct Rendering) is on.
configure outputs:
| Code: | # Video Output Support
x11 support yes
xrandr support yes
xv support yes
VDPAU support yes
VAAPI support no
CrystalHD support no
OpenGL video no
MHEG support yes
libass subtitle support yes |
0.26 (just tried) outputs "yes" for OpenGL video here.
I don't really understand the configure script, but I guess OpenGL video = no means also no OpenGL (these are 2 options in configure) which means no OpenGL menu painter.
Now the question is: Why does 0.27 think I do not have OpenGL?
| Code: | emerge --ask -v mythtv
These are the packages that would be merged, in order:
Calculating dependencies... done!

So, MythTV 0.27 configure uses pkg-config to find out, if OpenGL is available.
Unfortunately, this does not work correctly on Gentoo:
| Code: | # pkg-config --list-all | grep -i Qt | grep -i OpenGL | awk '{print $1}'
Variable 'exec_prefix' not defined in '/usr/lib/pkgconfig/libsasl2.pc' |
This should output something useful, but it doesn't.
First problem: The file from cyrus-sasl is broken.
Second problem: Because of this, pkg-config does not report the needed info.
Any suggestions? |
