The GNU Debugger (GDB) is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, C, C++, Objective-C, Free Pascal, Fortran, Go, Java [1] and partially others. [2]


GDB was first written by Richard Stallman in 1986 as part of his GNU system, after his GNU Emacs was "reasonably stable". [3] GDB is free software released under the GNU General Public License (GPL). It was modeled after the DBX debugger, which came with Berkeley Unix distributions. [3]

From 1990 to 1993 it was maintained by John Gilmore.[ citation needed] Now it is maintained by the GDB Steering Committee which is appointed by the Free Software Foundation. [4]
