You do need to compile anything, but runtime linker has to know where to
find this library.  For instance set LD_LIBRARY_PATH to the directory
containing this library when calling eclipse:
  $ LD_LIBRARY_PATH=/usr/lib/jvm/java-6-sun/jre/lib/i386/xawt eclipse
You can certainly tell eclipse to look for libraries in this directory so that
you do not have to set LD_LIBRARY_PATH, but I do not know eclipse.
