Hi (my first posting. I've just installed Mandrake 7.1 on a Dell Pentium Laptop with a 1 gig partition. Everything went well the second time (first time i tried a windows install with not enough free space and I lost everything on my computer!). Therefore three days later I am finally back to where i was...... However, I would love to get a simulator which i have downloaded from berkely called ns working on my machine... however it is failing to recognise that i have gcc-2.7XXX (default installation that was on mandrake after installation)... I have tried to download other gcc compilers in RPM format but the package installer wouldn't let me install them as I had gcc already on the computer. I have included the linux..i586..mandrake gcc compiler (cpp) file and (gcc) file in another directory on the defualt path in the .cshrc, .bashrc and .tshrc files (as I wasn't sure which one is the one that sets path variables in the bash shell. I know i haven't been too specific but I was wondering if someone could see through the mess of things I've written and provide a quick solution to my gcc compilation problem.
