In general the order of the -l options is important, at least if you have interlibrary dependencies, which is almost always the case with X applications. The "highest" level libraries are listed first, followed by "lower" level libraries until at the end you have libraries that do not depend on anything else (except maybe the C library, which is linked by default except in unusual circumstances). Consider the output of gtk-config --libs: -L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl -lXi -lXext -lX11 -lm Here we see that we high-level GTK+ and GDK libraries come first, followed by intermediate libs, and finally wrapping up with libX11 (the core X protocol library) and the math library, which of course won't be needing any symbols from fancy GUI libraries. -- G.
