2.11. Uninstalling All Software Collection Directories

Keep in mind that the yum remove command does not uninstall directories provided by those Software Collection packages and subpackages that are removed after the Software Collection runtime subpackage is removed.

To ensure that all directories are uninstalled, make those packages and subpackages depend on the runtime subpackage. To do so, add the following line with the %scl_runtime macro to the spec file of each of those packages and subpackages:

%{?scl:Requires: %scl_runtime}

Adding the above line ensures that all directories provided by those packages and subpackages are removed correctly as long as the runtime subpackage does not depend on any of those packages and subpackages.
