Dear Cygwin
I've just downloaded the full complement of CYGWIN and CYGWIN/X files with
the intent of doing builds of some standard X Windows / OpenGl (and also
Motif) programs . However, I am encountering difficulties. Could you
please help me with the following :
I'm unable to compile Kilgard's glxsimple.c on my Cygwin
installation. I've tried using the following command, which works on my
Redhat Linux 8.0 laptop :
gcc -o glxsimple glxsimple -lGL -LX11R6
but it resulted in a "no such file : GL/glx.h" error. I adjusted this to
gcc -o glxsimple glxsimple -I/usr/X11R6/include -lGL -LX11R6
which seemed to compile, but produced a "cannot find -lGL" from the linker.
After reading /usr/doc/opengl-1.1.0, I then tried
gcc -o glxsimple glxsimple -I/usr/X11R6/include -Lw32api -lopengl -LX11R6
which again appeared to compile, but resulted in a mound of "undefined
reference" messages to GL function calls, and some to X calls as well.
Can you please provide any help at all ? An explicit compile and link
instruction is what I need, but even the command to build Oliver Jones
"Hello World" (from his "Introduction to the X Window system") or something
from Kilgard (involving X, OpenGL, and Motif) on Cygwin would be extremely
helpful.
Thanks for the consideration.
Walt Michaluk
