I am in the process of installing CentOS 5.1. The gcc that came with it is... gcc-4.1.2-14.el5.i386.rpm. My problem is I have software that ran in RHEL-3 perfect and the version of gcc that was used was... gcc-3.2.3-47.i386.rpm. I received errors with the newer version that came with CentOS 5.1. I'm quite new to this and I'm unsure what to do. If i need to install the gcc-3.2.3-47 version I'm not sure how to do this and if I can have both versions on the server? I'd really appreciate some help.
