2.3 Optional configuration steps

On any platform, after installing the compiler you may wish to set some environment variables. The Free Pascal compiler recognizes the following variables :

• PPC_EXEC_PATH contains the directory where support files for the compiler can be found.
• PPC_CONFIG_PATH specifies an alternate path to find the fpc.cfg.
• PPC_ERROR_FILE specifies the path and name of the error-definition file.
• FPCDIR specifies the root directory of the Free Pascal installation. (e.g : C:\PP\BIN)

These locations are, however, set in the sample configuration file which is built at the end of the installation process, except for the PPC_CONFIG_PATH variable, which you must set if you didn’t install things in the default places.
