Hi,<br><br>I am trying to install VTK on Red Hat Enterprise Linux 6 with an ATI graphics card. I have installed the graphics card drivers and glxinfo gives me a value of 1 for 'direct rendering'. I am assuming it means OpenGL is installed correctly. The ATI Catalyst shows that the OpenGL version is 3.3.10750 Compatibility Profile Context. <br>
<br>First of all, running CMake on VTK gave me an error that it cannot read <b>/usr/include/GL/glx.h</b>. I checked and found that I have glxATI.h and glATI.h instead of glx.h and gl.h respectively. Hence, I created symbolic links to the respective files. This got rid of the CMake error but when building VTK I get a bunch of errors:<br>
