Advanced installation

You must use the advanced installation procedure if any of the following is true:

• You are maintaining multiple fix levels of the compiler on a single system.
• You do not wish to alter the system runtimes with the compiler installation.
• You are installing the product to a non-default location.
• You are installing the product on an IBM® i V7.1 PASE system.

To perform an advanced installation, you need to use the xlcndi Perl script provided with the installation image, to install XL C to a non-default directory and run multiple versions of XL C on a single system. The script is packaged in the xlccmp.13.1.0.ndi fileset. To avoid unexpected behavior during installation, do not modify this script.
