Merged Ross' patch for Hugs:
Tweak to the FPTOOLS_HAVE_OPENGL: when testing for the GLUT lib,
include the GL/GLU/GLX libs just discovered. While most platforms
don't require this, mysteriously some (e.g. OpenBSD) do.
GL_CFLAGS=
fi
- LIBS="$GLUT_X_LIBS"
+ dnl Keep the GL/GLU/GLX libs, but expand the rest to what GLUT needs.
+ dnl (Some systems, like OpenBSD, need the GL/GLU libs.)
+ LIBS=`echo "$LIBS" | sed "s@$GL_X_LIBS@$GLUT_X_LIBS@"`
FPTOOLS_SEARCH_LIBS([#include <GL/glut.h>], glutMainLoop, glut32 glut, have_glut=yes, have_glut=no)
