Hi!

Check if you have installed the MESA-devel rpms. You need them in order to compile your programs.

Gretz,

just to check the obvious: did you capitalize GL/gl.h. In windows I used to do just gl/gl.h, but linux is case sensitive with file names

I''m quite new to Linux too and I aslo have MDK 9.2. I''ve installed Anjuta as my IDE and it''s great. To use OpenGL, open rpmdrake (configuration - packages - install software) and search for GL and GLUT. install all of those MESA libs you find and also, if you use Anjuta, automake and autoconf (or find them on the web).

Now to use it: in Anjuta, open up the settings - compiler and linker and add /usr/X11R6/lib to the lib paths and /usr/X11R6/include to the inlude paths. now add "GL", "GLU" and "glut" to the libraries.

and in the program do this: #include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glut.h>

(after installing the GLUT lib, make sure you have libglut.so in your /usr/X11R6/lib dir, if you have libglut.so.3 or smth like that just make a copy and name it libglut.so)

You shouldn''t do that (make a copy of the library, that is). When something links to GLUT with -lglut it will look for the file libglut.so. When the linker finds libglut.so, the idea is that the linker will find out what major-version of GLUT libglut.so represents by what it''s pointing at. So, libglut.so should be a symlink to libglut.so.3 or, more commonly, a symlink to whatever libglut.so.3 points at.

Not only does that cause the linker to pick the correct major-version it will allow you to replace libglut.so.3 (or whatever) with a newer version and automatically have libglut.so point at it.

However, doing this manually isn''t the best way to go about it. One is meant to execute ldconfig (as root) after every installation (among other things) of libraries to one of the directories managed by /etc/ld.so.conf. Doing that should generate the "base" symlinks to all of the libraries if they don''t exist as well as cache the names of installed libraries.
