The Xmu Library is a collection of miscellaneous (some might say random) utility functions that have been useful in building various applications and widgets. This library is required by the Athena Widgets.
Starting in XFree86 4.1.0, and incorporated into X11R6.7 and later releases, a subset of the functions that do not rely on the Athena Widgets (libXaw) or X Toolkit Instrinsics (libXt) are provided in a second library, libXmuu.
Programs using either of these libraries are encouraged to determine the
correct compiler and linker options via the xmu
or
xmuu
module names for pkg-config,
such as:
cc -c xapplication.c `pkg-config --cflags xmu`
cc -o xapplication xapplication.o `pkg-config --libs xmu`
