The ARMCCnINC environment variable points to the location of the included header and source files that are provided with the compilation tools.

This variable might be initialized with the correct path to the header files when the ARM compilation tools are installed or when configured with server modules. You can change this variable, but you must ensure that any changes you make do not break the installation.

The list of directories specified by the ARMCCnINC environment variable is colon separated on UNIX and semi-colon separated on Windows, following the convention for the platform you are running on.

If you want to include files from other locations, use the -I and -J command-line options as required.

When compiling, directories specified with ARMCCnINC are searched immediately after directories specified by the -I option have been searched, for user include files.

If you use the -J option, ARMCCnINC is ignored.
