<div>Hi All, I am new to GATE and I have never worked on this kind of Source Code before, and I am having trouble installing it, I have been facing problems where source code does not compile.  I have been using this link '<a href="http://cc.in2p3.fr/docenligne/674">http://cc.in2p3.fr/docenligne/674</a>' to compile source code and I have problem with compiler compatibility. So I want to know what is the most recommended system I should use, like in Linux which 'GUI' I should use, and which processor , some good OpenGL  which are easily compaitible with GEANT and any other hardware specification. Because I have to use GATE for minimum requirement. As I am a student I have wasted 1 month on this, so please any one can guide me through the installation of GATE, it would be very helpful.
