Arguments

None

Default

OFF	Standard directories are in the include file search path.

Description

This option removes standard directories from the include file search path. It prevents the compiler from searching the default path specified by the INCLUDE environment variable.

On Linux* and OS X* systems, specifying -X (or -noinclude) prevents the compiler from searching in /usr/include for files specified in an INCLUDE statement.

You can use this option with the I option to prevent the compiler from searching the default path for include files and direct it to use an alternate path.
