Use this procedure if you want to install all compiler packages to a single non-default location. For example, rather than installing all packages into the default directory /opt/ibmcmp/, you could install them to a directory of your choice, such as /home/mydirectory/.
cd /cdrom ./xlc_install -prefix installation_pathFor additional arguments that you can specify for xlc_install, see xlc_install options.
rpm -ivh *.rpm --prefix installation_path
