It is highly recommended that you install
IBM® XL C/C++ for Linux®,
V11.1 to
the default location and use the procedure provided in
Basic installation.
However,
you will need to use alternate procedures for customized scenarios,
including the following: - You want to maintain more than one version of IBM XL C/C++ for Linux on
the same system.
- You want to upgrade or update an existing
version of IBM XL C/C++ for Linux that
is installed in a non-default location.
- You want to try out a new update of the compiler before removing
an existing installation from the default location.
In all of these scenarios, you can use the rpm utility
to install the compiler packages; you can also use the xlc_install utility
to install the compiler packages to a single, non-default location.
After you have successfully installed the compiler packages to a non-default location using rpm utility,
you need to manually configure the compiler environment using the new_install or vac_configure utility.
For configuration procedures, see Configuring IBM XL C/C++ for Linux, V11.1 (for advanced users).
