I'm executing a pro*c executable in linux and I've got segmentation fault error. But there is no core file dumped.
Thus, I want to debug the program using GDB debugging tool. However, I see that it is not installed on my Linux machine (a RHEL 5.3). How to install GDB debugging tool in linux? Do I need to download any package and install it, or does it come with RHEL?
Any help is appreciated.

First of all if you don't have a core dumped on your disk is because often by default the core size is limited to 0 byte, thus core are not dumped.
To check this and correct it, simply perform this in your shell just before running your program (in the same shell):
ulimit -c
ulimit -c unlimited
The first command will give you the limit size for core files, the second one will make it unlimited.
Now you can run your program and it will dump a core upon segmentation fault. You still need GDB though.
GDB is an installable package that come with the Red Hat installation DVDs. Red Hat offers a nice and simple interface to do this, check their online manual. Search for GDB, selct it and click Apply. It will request to insert the installation DVD.

@Hindol you could have said this in a friendlier and more constructive manner. And we all know that sometimes Google has the proper answer buried under tons of crap :) There is no reason I see why this question cannot be answered without being harsh. – Huygens – 2012-05-11T10:33:50.963
