Yes, that was just a typo. I think I will try to look at some screensave code. Maybe there are some compiling hints in there. Does anybody have any ideas?

I am trying to get a simple OpenGL program to compile. I think I am having linking issues. The problem is this error I get from the compiler: undefined reference to 'glXQueryExtension' Now, I call that function in my code. I found the prototype for it in /usr/X11R6/include/GL/glx.h. On the compiler line, I specify -I/usr/X11R6/include and (I think) the compiler can then resolve the #include <GL/glx.h> statement I have in my source code and, hence find the include file. Additionally, the book I am reading has me specify the following libraries: -lGL -lXext -lX11 I added the library directory flag: -L/usr/X11R6/lib where I find libGL.a, libXext.a and libX11.a are located. Well, I kept getting that error. So, I tried renaming the compiler libraries on the command line: -llibGL -llibXext -lX11 and tried other permutations to try to get this code to link. But, it won't and I am stuck. If any one out there has some insight into this, I would appreciate some help. Thanks very much, Chris
