** Description changed:
Binary package hint: nvidia-glx
I came across this when trying to ./configure mplayer with the
--enable-xvmc
flag to enable XvMC for nVidia, as described here:
http://www.penlug.org/twiki/bin/view/Main/LinuxHardwareInfoNvidia5200
The mplayer configure script
./configure --enable-xvmc
performs the following test compilation, to see whether the XvMC
libraries for NVIDIA are available (This appears to be the correct way):
cc -O4 -march=pentium4 -mtune=pentium4 -pipe -ffast-math -fomit-frame-
pointer -o test.o test.c -lXvMC -lXvMCNVIDIA -lXv -L/usr/X11R6/lib
-lXext -lX11 -lnsl -lpthread
where the file test.c contains the following:
#include <X11/Xlib.h>
#include <X11/extensions/Xvlib.h>
#include <X11/extensions/XvMClib.h>
int main(void) {
(void) XvMCQueryExtension(0,0,0);
(void) XvMCCreateContext(0,0,0,0,0,0,0);
return 0; }
Unless the symbolic link /usr/lib/libXvMCNVIDIA.so exists, and points
to libXvMCNVIDIA.so.1 the above compile/link command fails as follows:
/usr/bin/ld: cannot find -lXvMCNVIDIA
collect2: ld returned 1 exit status
I tried using "ldconfig" but it didn't help. It seems to me that at
the moment on Dapper Drake, the only workaround
that works for me is to manually create the symbolic link, like this:
cd /usr/lib && sudo ln -s libXvMCNVIDIA.so.1 libXvMCNVIDIA.so
I'm not sure if this is a bug in the nvidia-glx package,
or where the bug belongs, but it seems there's a symbolic link
- missing somewhere.
+ missing somewhere. This missing symlink was also mentioned
+ by Michael Holland on the MPlayer-users list:
+ http://lists.mplayerhq.hu/pipermail/mplayer-users/2006-July/061343.html
Thanks for reading.
