Hello,
I am a student teacher and I have been using AutoCAD for a while. When I found out about OpenCascade, I thought it may be a good alternative, but..........
I am a new Linux user running ubuntu 5.10. I have downloaded the OpenCASCADE_Linux.tgz file, and extracted it. I then typed /install.csh but I get the message "-su: install.csh: command not found", although it is there.
I have tried to install gcc 2.95, gcc 2.96, and gcc3.2, but only 2.95 is in the repository.
My Linux knowledge is very minute...Please help.

You need to do ./install.csh in the folder that has this file. So, from the command prompt go to the folder OpenCASCADE folder (where you extracted the tgz) by typing : cd [path] from the propmt. then do : ./install.csh

What's your platform? is it x86 or 64bits like amd64? Because if it's 64bits, chances are that the installer will not work. You have to either rebuild from source or install to a 32bits system (which run on 64bits platforms too, but you have to perform a new install from scratch.)
