Starting fglrun in debug mode

The runtime system can be started in debug mode with the -d option.

To start fglrun in debug mode, use the -d option of fglrun, for example:

fglrun -d myprog

This mode is typically used in development environments when using the command line tools.

The debugger can be used from the command line shell, but can also be called from a graphical debugging tool that understands the debugging commands of fglrun -d. The syntax of the commands is similar to the gdb debugger.

The debugger can for example be used alone in command line mode or with a graphical shell compatible with gdb such as ddd:

ddd --debugger "fglrun -d myprog"
