Uninstalling a basic installation

To uninstall the compiler from the default location, you can use either SMIT or installp to remove the compiler filesets.

If you attempt to remove a fileset that is required by another installed fileset, the selected fileset will not be removed unless its dependents are also being removed.

Using SMIT

The following steps illustrate how to uninstall IBM® XL C/C++ for AIX®, V11.1 using the SMIT interface:

Using installp

To uninstall IBM XL C/C++ for AIX, V11.1 using the installp command, enter the following command on the command line:
installp -ug filesets
where filesets is the list of filesets (wildcards accepted) to uninstall.
If you have XL Fortran installed in its default location, you must not remove any filesets which are shared between the compilers. In this case, filesets should be:
vac.\* vacpp.\* 
Otherwise, filesets are:
vac.\* vacpp.\* memdbg.\* xlmass.\* xlsmp.\*
To uninstall IBM Debugger for AIX, V7.1, enter the following command:
installp -ug ibmdebugger
