Using custom compiler configuration files

You can customize compiler settings and options by modifying the default configuration file or creating your own configuration file.

You have the following options to customize compiler settings:

The XL Fortran compiler installation process creates a default compiler configuration file. You can directly modify this configuration file to add default options for specific needs. However, if you later apply updates to the compiler, you must reapply all of your modifications to the newly installed configuration file.
You can create your own custom configuration file that either overrides or complements the default configuration file. The compiler can recognize and resolve compiler settings that you specify in your custom configuration files with compiler settings that are specified in the default configuration file. Compiler updates that might later affect settings in the default configuration file do not affect the settings in your custom configuration files.
