The image includes filesets for the compiler components.
Preparing the electronic distribution package
If you have downloaded the XL C electronic
distribution package, xlc.12.1.0.aix.GM.tar.Z, follow
the steps described in this topic before the installation.
National language support
When fileset names differ only by the locale code, you
can choose to install only the filesets that are relevant to your
desired language and location. The LANG environment variable determines
which message catalogs are used. The en_US (English) message catalogs
are installed by default. If LANG is not defined or is assigned an
unsupported locale, en_US message catalogs are used. This topic introduces
a list of available locales.
