Compiling GLUT Opengl Programs in Linux

Hello all.. I currently have Red Hat Linux 7.2 and I am trying to compile a opengl program that I wrote using GLUT. I know that Linux uses MESA, but I am not sure how to link the program to the appropriate libraries as it is compiled. This is easy to do in Win32, but since I am new to linux I am unfamiliar of how to do this. IF anyone could help, I would really appreciate it. Thanks! Bill Blair

To link a library using GCC you use -llibname (that''s an L). So, to link OpenGL we use -lGL, GLU is -lGLU, and GLUT is -lGLUT, I''m pretty sure. If you need to link another library, look in one of your library directories to find the actual file. Remove the "lib" from the front and everything after the first period, and then you have a name that can be appended to -l.

Thanks, but I believe redhat uses MESA and not OpenGL. Can anyone give me an example how to compile a program using mesa and where the libraries might be so that I can use them?

Thanks!

MESA is OpenGL, just without the official certification from SGI. I compile OpenGL applications in Linux all the time using those extact command line options (excluding GLUT), so I''m very sure they work

Okay, great! I think I understand...so the command on the command line looks like this:

>gcc testgl.c -lGL -lGLU -lGLUT

Is that it? or do I just need replace GL, GLU and GLUT with the actual path names. What about object files? Do I need to create that as well? Can I create a make file to do all this?

Thanks for being patient...compiling C programs on LINUX is very new to me...

Thanks!

Not sure about the glut part, but the rest is right. Its same even if you use Mesa. Finally you would have to specify path only if the libraries aren''t already in your existing path.

You can create object files like this

gcc -c file1.c
gcc -c file2.c

finally get the executable
gcc file3.c file1.o file2.o -o executable_name

Yes, you can make a file to do all of it - most programs come with a Makefile. "man make" and read a lot of makefiles.
