I'm using macports to install OpenGL (mesa) since High Sierra does not have the X11 parts of it. In the Makefile there are includes and LFLAGS that need to be patched:
diff -ur cgx_2.13/src.orig/Makefile cgx_2.13/src/Makefile --- cgx_2.13/src.orig/Makefile 2018-04-05 13:32:06.000000000 -0500 +++ cgx_2.13/src/Makefile 2018-12-11 20:50:49.000000000 -0600 @@ -3,13 +3,13 @@ -I/usr/include \ -I/usr/include/GL \ -I../../libSNL/src \ -I../../glut-3.5/src \ - -I/usr/X11/include + -I/opt/X11/include LFLAGS = \ - -L/usr/lib64 -lGL -lGLU \ - -L/usr/X11R6/lib64 -lX11 -lXi -lXmu -lXext -lXt -lSM -lICE \ - -lm -lpthread -lrt + -framework OpenGL -framework GLUT \ + -lX11 -lXi -lXmu -lXext -lXt -lSM -lICE \ + -lm -lpthread This seems to work but I’m not sure it's proper.
