Can anybody please tell me what are the steps to follow when there's an existing gcc version which does not respond to gcc -v and we need to install a newer gcc rpm version

since I've tried installing so many gcc rpm versions how am i going to remove them or will that not going to be an issue

i also want to know how "make distclean" command works and what it does
because I've set so many environmental variable in /etc/profile
for gcc

when I'm installing gcc rpm should i also set environmental variables if so where should i set them in .profile or /etc/profile

If you want to keep the existing version of gcc and install a new version then you need to use the following,

where gcc-version.rpm is the filename of the rpm.

This will keep the existing gcc RPM intact and install gcc-version.rpm separately. For your make distclean question, you can check the following article,

Just check the gcc rpm which are existing on the current system
rpm -qa | grep gcc
if you wish to upgrade current version, download the all gcc dependent rpm's and upgrade your existing gcc
rpm -Uvh

No need

check this link for different's of clean and distclean
http://www.linuxquestions.org/questi...-clean-284353/

Thanx for all your support but question still exists..
i got results for following commands
and I'm confused this Red hat Version does have gcc installed or not
