Where to Find Installation Instructions

To install the compiler, refer to these documents (preferably in this order):

1. Read any Memo to Users document that comes with the compiler to see if there are any important notices you should be aware of or any updates you might need to apply to your system before doing the installation.
2. Read the AIX Installation Guide to understand the full procedure for installing optional software from the distribution medium. This book provides good step-by-step instructions that should answer all your questions and should help you to solve any installation problems.

   If you are already experienced with AIX software installation, you can use the installp or smit installp command to install all the images from the distribution medium.

After successfully installing the product, read the file called /usr/lpp/xlf/DOC/README.xlf, and follow any directions it gives. It contains information that you should know and possibly distribute to other people who use XL Fortran.

Using the Compiler on a Network File System

If you want to use the XL Fortran compiler on a Network File System server for a networked cluster of machines, use the Network Install Manager.

The following directories under /usr contain XL Fortran components:

• /usr/bin contains the compiler invocation commands.
• /usr/lib contains the libraries.
• /usr/include contains the include files, some of which contain definitions that XL Fortran uses.
• /usr/lib/nls/msg contains the message catalog files that XL Fortran uses.
• /usr/lpp/xlfrtemsg contains the default message catalog files that are used by XL Fortran programs.
• /usr/share/man/cat1 contains the compiler man pages.
• /usr/share/man/info/en_US/xlf/pdf contains the PDF format of the XL Fortran publications.
• /usr/share/man/info/en_US/xlf/html contains the HTML format of the XL Fortran publications.
• /usr/lpp/xlf contains all other commands and files that the compiler needs.

You must also copy the /etc/xlf.cfg file from the server to the client. The /etc directory contains the configuration files specific to a machine, and it should not be mounted from the server.
