Linking Shared Libraries

OpenGL is supported on workstations using shared libraries that must be linked with the application program.

When you compile your OpenGL programs, you must link the application with the OpenGL library libGL. Notice that the OpenGL library is dependent on the HP X extensions library (libXext).

An ANSI C compile line will typically look similar to this:

c89 program.c \
  -I/opt/graphics/OpenGL/include \
  -L/opt/graphics/OpenGL/lib \
  -lXext -lGL -lX11

Note that to compile your application using ANSI C, you can also use the cc command with either of these command line options: +Aa or +Ae.

If you are going to compile your application using HP's ANSI C compiler or cfront C compiler, use one of the following commands:

Title not available (Linking Shared Libraries)

aCC: — used to compile an ANSI C application.
CC +a1: — used to compile a cfront C application.

See the Graphics Administration Guide for more information on compiling.

This table summarizes the shared libraries and X11 directories that are linked on the command line example above.
