Next: Debugger Operation, Up: Debuggers
There are several commands for starting a debugger, each corresponding to a particular debugger program.
gud-xdb-directories
to specify directories to search for source
files.
Some versions of SDB do not mention source file names in their
messages. When you use them, you need to have a valid tags table
(see Tags) in order for GUD to find functions in the source code.
If you have not visited a tags table or the tags table doesn't list one
of the functions, you get a message saying ‘The sdb support
requires a valid tags table to work’. If this happens, generate a valid
tags table in the working directory and try again.
Each of these commands takes one argument: a command line to invoke the debugger. In the simplest case, specify just the name of the executable file you want to debug. You may also use options that the debugger supports. However, shell wildcards and variables are not allowed. GUD assumes that the first argument not starting with a ‘-’ is the executable file name.
