I am using a Matrox G400 DH videocard, so I'd like to use accelerated functions when ever possible. So, I added Matrox to my use settings. My use settings look like this: USE="mmx 3dnow dvd -gnome kde qt alsa cdr cups foomaticdb ppds matrox mpeg avi jpeg png tiff gif arts oggvorbis opengl python quicktime xmms xv fbcon directfb" When trying to emerge mplayer, I get the following output while it's trying to compile the mga_vid driver: gcc -O2 -D__KERNEL__ -DMODULE -include /usr/src/linux/in clude/linux/modversions.h -Wall

ERROR: media-video/mplayer-1.0_pre4 failed. !!! Function src_compile, Line 275, Exitcode 2 !!! Failed to build matrox driver! It looks like a file is not there that should be. Reproducible: Always Steps to Reproduce: 1. add matrox as a use clause 2. emerge mplayer 3. Expected Results: I expected mplayer to build
This module is unmaintained, and incompatible with post-2.5 versions of kbuild as far as I know, so it won't work with 2.6. However, and this is guesswork, there is an option in .config called CONFIG_MODVERSIONS. It's unset here, but enabling it might just fix the problem.
This should work with newer releases. Please give the latest ~x86 version a try. *** This bug has been marked as a duplicate of 40616 ***
