GNU debugger. The FSF's symbolic debugger for C, C++ and other languages. Developed by many people but most recently Fred Fish <[email protected]>, Stu Grossman <[email protected]> and John Gilmore <[email protected]> all of Cygnus Support. GDB fills the same niche as dbx. Programs must be compiled to include debugging symbols.

Version 4.11. Distributed under GNU CopyLeft. It runs on most Unix variants, VMS, VXWorks, Amiga and MS-DOS.

FTP gdb-*.tar.[zZ] from a GNU archive site. E-mail: <[email protected]> (bug reports).
