I have need of both the gcc that comes with SUSE 10 (4.0.2) and a 3.4.x version of gcc as well. Is it possible to have both installed at the same time? I would guess that things like include files would have to be sorted. But does anyone know of a general guide for doing this sort of thing? The SUSE 10 one would be the default that should be invoked as usual. The gcc 3.4 could require, say, environment variables to be set. The reason for this is I want to compile kernel modules for some other system, and it seems that it is not happy if they are compiled with SUSE's 4.x gcc. The kernel itself was compiled with 3.4.4. I can chroot to an environment that will run gcc 3.4.4, but I would prefer to just run the 3.4 compiler from a Makefile in SUSE 10.0. Make sense? -- Roger Oberholtzer OPQ Systems AB
