Thanks for the advice. Bear with me, I'm a newbie at Linux. I checked for the gcc package with the 'rpm -q gcc' and it said: 'gcc-2.96-112', which I assume means it is installed. For the kernel source and kernel header where can I find them. when I type 'rpm -q glibc-kernheaders' it tells me 'glibc-kernheaders-2.4-7.16', does that mean that the kernel header is for kernel 2.4-7?
