NAME
gdb - Project GNU's DeBugger
SYNOPSIS
gdb [ options ] See documentation mentioned below.
DESCRIPTION
gdb is a source level symbolic debugger for C programs,
created by Richard M. Stallman (rms) for the GNU Project,
and distributed by the Free Software Foundation. Eventually
GNU (Gnu's Not Unix) will be a complete replacement for
Berkeley Unix, all of which everyone will be able to use
freely. See the GNU Emacs man page for pointers to more
information.
gdb has something of the flavor of dbx, but has more
features and power. It can also be used to debug o/s ker-
nels, but needs to be configured differently for that task.
Project GNU isn't using Unix man pages. Its style of com-
plete documentation can be found by:
The help and info commands inside gdb.
In the Info system in GNU Emacs. Type C-h i, and follow the
directions. This is equivalent to the reference manual for
gdb, and has about 55 pages of text.
gdb could be extended to work with other languages (e.g.
Pascal) and machines (e.g. encores). If you like, copy the
sources and give it a try. When you have it working send
diff -c's of the changed files to bug-gdb@prep.ai.mit.edu
(fuller details below), so they can benefit everyone.
DISTRIBUTION
gdb is free; anyone may redistribute copies of gdb to anyone
under the terms stated in the gdb General Public License, a
copy of which accompanies each copy of gdb, is readable with
the info command inside gdb, and which also appears in the
gdb reference manual.
Copies of gdb may sometimes be received packaged with dis-
tributions of Unix systems, but it is never included in the
scope of any license covering those systems. Such inclusion
would violate the terms on which distribution is permitted.
In fact, the primary purpose of the General Public License
is to prohibit anyone from attaching any other restrictions
to redistribution of gdb.
You can order printed copies of the gdb reference manual for
$10.00/copy postpaid from the Free Software Foundation,
which develops GNU software (contact them for quantity
prices on the manual). Their address is:
Free Software Foundation
1000 Mass Ave.
Cambridge, MA 02138
As with all software and publications from FSF, everyone is
permitted to make and distribute copies of the gdb reference
manual. The TeX source to the gdb reference manual is also
included in the GNU Emacs source distribution.

BUGS
There is a mailing list, bug-gdb@prep.ai.mit.edu on the
internet (ucbvax!prep.ai.mit.edu!bug-gdb on UUCPnet), for
reporting gdb bugs and fixes. But before reporting some-
thing as a bug, please try to be sure that it really is a
bug, not a misunderstanding or a deliberate feature. We ask
you to read the section ``Reporting Emacs Bugs'' near the
end of the GNU Emacs reference manual (or Info system) for
hints on how and when to report bugs. Also, include the
version number of the gdb you are running in every bug
report that you send in.
Do not expect a personal answer to a bug report. The pur-
pose of reporting bugs is to get them fixed for everyone in
the next release, if possible. For personal assistance,
look in the SERVICE file (see the GNU Emacs man page) for a
list of people who offer it.
Please do not send anything but bug reports to this mailing
list. Send other stuff to gnu@prep.ai.mit.edu (or the
corresponding UUCP address). For more information about GNU
mailing lists, see the file MAILINGLISTS (see the GNU Emacs
man page). Bugs tend actually to be fixed if they can be
isolated, so it is in your interest to report them in such a
way that they can be easily reproduced.
No bugs are known at this time.
