Compiling gcc
 

I have donloaded the source code of the latest gcc compiler...

How do i compile it and install it?

Well, assuming you have a previous version of gcc, http://gcc.gnu.org/install/ will tell you how to configure, build, and install a new version.

If you don't have a previous version of gcc you will need to download a binary package from your distributions site. Gcc is a chicken and egg type situation. Gcc needs gcc to be compiled.

Ok I downloaded the necessary files... made a new directory called objdir and from that directory in the terminal I issued the command...


../configure
../make
../make install


after this when I issue the command


rpm -qa | grep gcc


the output shows the previous installation of gcc...
How do I replace the previous version with the new version?
