You can customize compiler settings and options by modifying
the default configuration file or by creating your own.
You have the following options to customize compiler
settings:
- The XL C/C++ 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 you specify in your custom
configuration files together with compiler settings specified in the
default configuration file. Compiler updates that might later affect
settings in the default configuration file does not affect the settings
in your custom configuration files.
For more information, see Using custom compiler configuration files in
the XL C/C++ Compiler Reference.
