Other GNU/Linux tips

If you have X installed in nonstandard locations, then you might encounter the following error in compilation:

/usr/bin/ld: cannot find -lX11

To fix it:

• Find the path to the libX11.so file:

  $ cd / $ find . -name libX11.so

• append -L/path/to/the/found/file's/directory/location to the lib headers in the gcc command.

The program will then compile.
