gcc questions

Hi,

I've got Fedora core4 with gcc4. When trying to patch a new kernel (2.6.10) with a RTAI patch I get an error which is caused by the fact that the patch does not support gcc4 and I need to use gcc 3.3.x instead.

Do I need to remove gcc4.0 before installing gcc 3.3.x or can the two coexist on the same system?

When doing 'make' on the new kernel+patch, how do I specify it to use gcc3.3 and not gcc4.0 ?

Thanks

You can normally install both versions of GCC on the same system. The normal method for telling the build scripts to use a specific version is with the CC environment variable, e.g.:

Code:

export CC=/usr/bin/gcc-3.3

make sure you don't overwrite anthing to do with your current compiler
so for safetys sake put the new (older) one in /opt directory
