GDB: The GNU Project Debugger
What is GDB?
GDB, the GNU Project debugger, allows you to see what is going on
`inside' another program while it executes -- or what another program
was doing at the moment it crashed.
GDB can do four main kinds of things (plus other things in support
of these) to help you catch bugs in the act:
- Start your program, specifying anything that might affect its behavior.
- Make your program stop on specified conditions.
- Examine what has happened, when your program has stopped.
- Change things in your program, so you can experiment with
correcting the effects of one bug and go on to learn about another.
The program being debugged can be written in Ada, C, C++, Objective-C,
Pascal (and many other languages). Those programs might be executing
on the same machine as GDB (native) or on another machine (remote). GDB
can run on most popular UNIX and Microsoft Windows variants.
GDB version 7.0.1
Version 7.0.1 of GDB, the GNU
Debugger, is now available for download. See the ANNOUNCEMENT for details
including changes in this release.
An errata list (PROBLEMS) and documentation
are also available.
