1. I downloaded gcc-3.2.tar.gz from gnu.org, I untarred and unzipped it. Then follow with commands...
#./configure
#make
#make install
But gcc/g++ does not work at all. What I did wrong?
My previous version is gcc-2.96.
2. How to rebuild kernel? Please anyone give me any web sites providing that (Red Hat 7.2 with downloaded patch-2.4.19.gz).
