Advanced Installation Options

This section provides some guidance on some more advanced FRED Local installation options.

configuring FRED_HOME

The FRED_HOME environment variable is used to locate the FRED executable and store the results of FRED simulations. By default, the installer will set FRED_HOME to the fred directory under your home user directory as defined by the HOME environment variable. This is the recommended setup for running FRED, though if you prefer to use an alternate directory you may set FRED_HOME before running the installer.


In our examples, we assume that environment variables can be accessed without quotes, as in $FRED_HOME. If your path has spaces in it, then this will produce an error, and you should access this and other environment variables surround by double quotes, as in "$FRED_HOME".
