[mythtv-users] gentoo, nvidia 1.0.7676, and xvmc (undefined symbols)

[Jesse Guardiani]

Hello,

I have the following software installed:
media-video/nvidia-kernel-1.0.7676 *
media-video/nvidia-glx-1.0.7676-r1 *
media-video/nvidia-settings-1.0.20050729 *
x11-base/xorg-x11-6.8.2-r3 *

When I try to build mythtv-0.18.1 with
the nvidia USE flag (thus enabling XvMC),
I get these errors:

g++  -o mythfrontend main.o manualbox.o playbackbox.o viewscheduled.o globalsettings.o manualschedule.o programrecpriority.o channelrecpriority.o statusbox.o previousbox.o customrecord.o moc_manualbox.o moc_playbackbox.o moc_viewscheduled.o moc_manualschedule.o moc_programrecpriority.o moc_channelrecpriority.o moc_statusbox.o moc_previousbox.o moc_customrecord.o   -L/usr/qt/3/lib -L../../libs/libmyth -L../../libs/libmythtv -L../../libs/libavcodec -L../../libs/libavformat -lmythtv-0.18.1 -lmythavformat-0.18.1 -lmythavcodec-0.18.1 -lmyth-0.18.1 -lfreetype -lmp3lame -lasound -L/usr/X11R6/lib -lXinerama -lXv -lXxf86vm -lXvMCNVIDIA -lXvMC -lGL -lGLU -lqt-mt -lXext -lX11 -lm -lpthread

/usr/X11R6/lib/libXvMCNVIDIA.so: undefined reference to `_xvmc_destroy_subpicture'

The build stops shortly after that. I'm
compiling with distcc (but I've never had
problems building 0.18.1 under distcc before),
and the libXvMCNVIDIA.so does indeed seem to
have undefined symbols:

# nm -D /usr/X11R6/lib/libXvMCNVIDIA.so | grep _xvmc_create_context
         U _xvmc_create_context

Has anyone else seen this? I'd love to give XvMC a
try on my GeForce MX 5200, but I've got to build it
in first! :)
