Specifying Source Path Substitution Rules

The debugger assumes that all source files are stored in the same directory as they were at compile time. If the sources are placed in different directories, you can add a source path substitution rule using the set substitute-path or map source directory command. This rule replaces the source directory paths automatically.

You need to specify a source path substitution rule if you can access source files from a path other than that of the compilation environment.
