Hi Xorcist,
I currently use Mandrake 9.0 and installed Kylix 3 ( Both C++ and Pascal complier ) onto it without a hitch. I have only ever used Gnome and KDE as Window managers so do not know if it would work with Black Box. I also know some people who swear by Suse 8.x and say that it works fantastically with Kylix. I have not had any feedback about people using Redhat however.

The Kylix installer will let you know if your version of Linux does not support the things it requires. As far as I am aware, at least in the Pascal compiler ) I did not have a need to recompile the OS in order to debug a Kylix app, but then I am only working at the GUI level using SDL or OpenGL.

I hope some of this information proved usefull.
