Many thanks, Mike. It works! Brilliant! However, I got some other
problems:
------------------
/usr/ccs/bin/ld: Unsatisfied symbols:
glutInitWindowSize(code)
glutInitDisplayMode(code)
glutMainLoop(code)
glutCreateWindow(code)
glutInitWindowPosition(code)
glutInit(code)
collect2:ld returned 1 exit status
gmake: ***[glutw] Error 1
--------------------

So what's the problem? Many thanks in advance.

It sounds like you just didn't link with libglut or linked with
it before the code that used it. It is available on HP-UX as
/opt/graphics/OpenGL/contrib/libglut/libglut.a which you can
use with -L/opt/graphics/OpenGL/contrib/libglut -lglut .
Because it is an archive library it must appear in the link line
after the file that calls the glut functions. If it is listed too
early then the linker won't know to pull in the required functions.

The version of glut shipped with HP-UX is quite old. If you have
code that uses newer glut features you will need to compile a newer
version. You can find that at
http://www.opengl.org/resources/libraries/glut/glut_downloads.php
.
