Any ideas? ld.so.conf is for the dynamic linker. You need to get -L paths to the linker somehow. freeglut isn't helping you out by trying to figure out where X is installed using pkg-config. They're also not really following the use of AC_PATH_XTRA from autoconf where you could use --with-x-libraries=/opt/xorg/lib. Probably you just need to run with LDFLAGS=-L/opt/xorg/lib for this package. -- Dan -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

That is strange. It might be some bug with pkg-config, that is if
Freeglut is using it.
pkg-config --libs gl
-lGL
It should print -L/path/to/libGL.so -lGL since gl.pc contains:
Libs: -L${libdir} -lGL
and libdir for my setup is
libdir=/usr/lib
You can expand LD_LIBRARY_PATH to $XORG_PREFIX/lib if necesary, but this
issue should be investigated first.

Dan was right about ld.so.conf. Like LD_LIBRARY_PATH, it only resolves
libraries at run time. The gl.pc file is correct and it is in the
plg-config path, but the freeglut demos are quite old and don't use
the .pc files.
The are two ways I've found to fix this:
LDFLAGS=-L/opt/xorg/lib ./configure ...
or
export LIBRARY_PATH=$XORG_PREFIX/lib
./configure ...
I think I will add the 2nd for for the educational value. I don't
think we use it anywhere else.
