[CLAM] CLAM compilation error - OpenGL

[Martin Rocamora]

Hi all!

I work on a multimedia group at university 
(http://iie.fing.edu.uy/investigacion/grupos/gmm). We're working on MIR 
and sound synthesis. We're interested in adopting CLAM as framework. I'm 
trying to compile it but I have the following problem.

I have already solved all the needed dependencies, however I get this 
error message:

---------------------------------
# scons configure with_osc_support=no with_id3_support=no
...
"Checking for glBegin() in C library GL... no
Could not find OpenGL library! Please install the development library 
supplied by your OpenGL driver vendor"
---------------------------------

System: Toshiba A55 Laptop (Centrino 1.5)
OS: Linux - Mandriva 10.2

I have an Intel 855GM integrated graphics controller, which is supported 
with 3d accceleration, and I'm using the right driver (i810).(*)

If I am not wrong, it seems I have the needed packages installed (libGL, 
libglut ). (**)

So, what am I missing?
Thanks, and I look foward to using the tool!

Martín.
