On some Linux distributions (''Slackware'' for instance), compiling fails because a GL related library doesn't have a link in the <tt>/usr/lib</tt> directory.  If the compile fails because it can't find <tt>-lGLU</tt>, here are two ways to fix it:

= Solution as Root =

If you have root access to the system, you can create a link to the library in question with just a little bit of command line magic.  Go to a console and enter:

 $ ln -s /usr/X11R6/lib/libGLU.so /usr/lib/libGLU.so

After that, you can run make again and it should finish compiling.

= Solution as User =

You don't have root access?  Never fear, we can still fix the problem.  It'll just be a tad more difficult.

Navigate to the <tt>fs2_open/code</tt> directory and locate a file named <tt>Makefile</tt> (not Makefile.rm or Makefile.in or Makefile.anything).  Open it in your favorite text editor and make the following changes.

Find this line (line 457 in mine):
 FS2_LDFLAGS =  -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -lGL -lGLU -lopenal \
   -logg -lvorbis -lvorbisfile

And replace it with this:
 FS2_LDFLAGS =  -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -lGL -lopenal -logg \
   -lvorbis -lvorbisfile -L/usr/X11R6/lib -lGLU 


Also find this one (line 565 in mine):
 AM_LDFLAGS =  -g  -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -lGL -lGLU -lopenal \ 
   -logg -lvorbis -lvorbisfile

And replace it with this:
 AM_LDFLAGS =  -g -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -lGL -lopenal -logg \
   -lvorbis -lvorbisfile -L/usr/X11R6/lib -lGLU

Then run <tt>make</tt> from the <tt>fs2_open</tt> directory, and watch the magic happen.
