This article talks about debugging tools for applications in C on Linux
platforms. Most of the tools are freely available on all major
platforms with very wide user support. The tools help in static
analysis of code as well as assist in dynamic evaluation of code.
note that tools listed here are suggestions of the author. This list is
not a standard one. Changes have to be done in it depending upon the
nature, scope and details of the application to be developed.
1. Dmalloc
The debug memory allocation or Dmalloc library is a freeware debugging
tool which has been specially designed as a drop in replacement for the
system's malloc, realloc, calloc, free and other memory management
routines while providing powerful debugging facilities configurable at
runtime. It makes changes during compile time and donot add runtime
changes in binary. These facilities include such things as memory-leak
tracking, fence-post write detection, file/line number reporting, and
general logging of statistics. The library is reasonably portable
having been run successfully on at least the following operating
systems: AIX, BSD/OS, DG/UX, Free/Net/OpenBSD, GNU/Hurd, HPUX, Irix,
Linux, MS-DOG, NeXT, OSF, SCO, Solaris, SunOS, Ultrix, Unixware,
Windoze, and even Unicos on a Cray T3E. It has full support for
programs the debugging of POSIX threads.
The package includes the library, configuration scripts, debug utility application, test program, and documentation.
2. Valgrind
Valgrind is a GPL distributed system for debugging and profiling
x86-Linux programs. I can also be helpful for programs for platforms
other than x86 since behavior of x86 binary is similar to other
binaries. The accompanying tools with Valgrind automatically detect
many memory management and threading bugs, avoiding hours of
frustrating bug-hunting, making programs more stable. It supports a
through detailed profiling to help speed up the programs.
The Valgrind distribution includes four tools: two memory error detectors, a thread
3. Electricfence
Electric Fence is a freeware library that can be used for C programming
and debugging. It can be linked at compile time and it will warn about
possible problems such as freeing memory that doesn't exist, etc. It is
basically a memory profiling tool. However currently it is available
only on HP-Unix platform (I am not very sure though).
4. GDB
This is the Gnome Debugger which comes as a freeware support package
with freeware Linux distribution like Red Hat, Slacware, and Debian
etc. It has full support of many languages like C, C++, and Perl etc.
It helps to debug the binaries of these languages in modes like single
step, multiple step or complete run. It also has provisions of setting
break points and trace value.
It is helpful for stub testing, functional flow checking and bound checking.
this is readily available with all flavours of Linux andUnix platforms and is amply supported in user community.
5. Insight
Insight is a graphical user interface to GDB, the GNU Debugger written
in Tcl/Tk by at Red Hat, Inc. and Cygnus Solutions Insight provides all
features provided by GDB along with Graphical debugging interface
replacing traditional command based interface.
6. Memprof
MemProf is a free ware memory Profiling and memory leak detection tool
which comes as an addendum to common Linux distributions. It can
generate a profile how much memory was allocated by each function in
the program. It can scan memory and find blocks that have been
allocated but are no longer referenced anywhere (dead code).
MemProf works by pre-loading a library to override the C library's
memory allocation functions and does not require recompiling the
program. One advantage MemProf has over some other similar tools that
are available is that it has a nice GUI front-end and is relatively
easy to use.
