In order to use GPHIGS-GUI the following libraries must be available :
- Motif (minimum level of 1.1) (libXm.a)
- Intrinsics (libXt.a)
- X- window (libX11.a)
GPHIGS-GUI functions may be accessed simply by linking with the libgphigsgui.a library.

To link with GPHIGS_GUI, simply replace libgphigsc.a by libgphigsgui.a in the link or Makefile utility. In order to use GPHIGS-GUI the corresponding license must be held. Any program that requires using GPHIGS-GUI must therefore open PHIGS (popen_phigs).
