This section lists the procedures you must perform before, during, and after a basic installation.
If the conditions listed in Basic installation match your needs, then a basic installation is the easiest and fastest method you can use to install. A basic installation allows you to install the latest version of IBM XL Fortran for Linux, and configure the compiler, all through the use of a single installation tool.
If you are using the basic installation to install IBM® XL Fortran for Linux, V15.1, the previous version of the XL compiler is not uninstalled, only the Fortran runtime libraries and SMP runtime library are migrated to the new versions.
