Compiling OpenGL code with GCC

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 using FreeBSD 4.4 with GCC 2.95. 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
On the compiler line, I specify
and (I think) the compiler can then resolve the
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:
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,
