Hi, Good Morning. I am trying to install gcc-3.4.6.tar.gz on RHEL6 which has gcc 4.4.2 already installed. Here are the steps followed. 1. Downloaded gcc-3.4.6.tar.gz 2. tar -zxvf gcc-3.4.6.tar.gz 3. Navigated to gcc-3.4.6 4. Executed below command ./configure --prefix=/usr/local/gcc3463 --mandir=/usr/local/gcc3463/man --infodir=/usr/local/gcc3463/info Next executed this command make boostrap also tried with only make. So please do help me on how to install the gcc 3.4.6 on RHEL6. Any help would be appreciated Thank You
