installing another version of gcc

kulmis · 06-21-2005, 08:16 AM

Hi,

How can I install another version of gcc without deleting the current version on my computer? What I want to do is to compile a kernel module which should be done with the same gcc version with which the kernel was compiled. I have updated the system after installing so now the gcc is newer than the version used to compile the kernel.
I wouldn't want to downgrade my current gcc nor update my kernel.

I'm running Fedora Core 3.

First, check to see what you have installed:

Code:

$ gcc<tab>tab>

on my systems shows

Code:

gcc              gcc32            gccmakedep-i386
gcc3             gccmakedep
$ gcc --version

Often installing a new compiler version leaves the old one available.

it depends a bit on what version you are looking to add
basically you put them in the /opt directory
since it's a bit hard to explain in detain without knowing exactly what you are doing
the best thing is to get a copy of the lateset
Beyond Linux from Scratch book from cvs and in there are instructions for compiling
GCC-3.4.1
GCC-2.95.3
GCC-3.3.4
(these are kind of the standard ones)
complete with patches configure and details so they will work right
