Summary
of GDB
The purpose of a debugger
such as the GNU debugger, GDB, is to allow you to see what is going on
inside another program while it executes—or what another program
was doing at the moment it stopped. GDB can do four main kinds of things
to help you catch such problematic things that are called “bugs.”
-
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 problem affecting your program.
You can use GDB to debug programs
written in C and
C++.
Support for Modula-2 and
Chill is partial. For information on Modula-2, see Modula-2.
There is no further documentation on Chill yet.
Debugging Pascal, a program
which use sets, subranges, file variables, or nested functions, does not
currently work. GDB does not support entering expressions, printing values,
or similar features using Pascal syntax.
GDB can be used to debug
programs written in Fortran, although it does not yet support entering
expressions, printing values, or similar features using Fortran syntax.
It may be necessary to refer to some variables with a trailing underscore.
For some specific discussion
on GDB, see the following documentation.
