We recently purchased and added the Red Hat Developer Toolset 2 channel to one of our RHEL 5.9 boxes so that we could upgrade GCC 4.1 to 4.8. We ran yum install devtoolset-2-2.0-19.el5.noarch to upgrade. Upon completion, GCC 4.1 was still located under /usr/bin/gcc and GCC 4.8 appears to have been installed to /opt/rh/devtoolset-2/root/usr/bin/gcc. This means that GCC 4.1 is still in the path and is the one running which isn't what we had anticipated. Trying to figure out how the upgrade is supposed to work.
Should we have...
<1> Uninstalled all the GCC 4.1 packages prior to installing GCC 4.8?
<2> Installed as we did but then create symbolic links or copy the GCC binaries to /usr/bin/?
<3> Do the upgrade some other way?
Looking for some guidance on the proper way to complete the upgrade and any other relevant guidance.
