Advanced installation

Limitations of nondefault installation
Although nondefault installation gives you more freedom to choose how many versions of XL C/C++ to keep on your system and where to install them, in many ways a nondefault installation is also more restrictive, demanding to implement, and difficult to maintain than a basic installation.

Tasks for advanced installation
Before you perform an advanced installation, you must make sure that you have a user account with administrator privileges and that your system meets all system requirements. You might also want to uninstall any previous versions of XL C/C++ on your system. After you have finished installing the compiler, you must confirm that the installation has been successful and enable the man pages of the compiler.

Nondefault installation procedure
To install XL C/C++ to a nondefault location, first use installp to install the xlCcmp.13.1.3.ndi fileset, and then use the xlCndi Perl script included in that fileset to install the compiler.

Running XL C/C++ from a nondefault location
The compiler invocation commands are installed to /target_dir/opt/IBM/xlC/13.1.3/bin/, where target_dir is the location of the compiler as set by the -b flag during the nondefault installation.
