Re: gdb is linux

gdb is a debugger to debug you code

when you compile the code compile with the opption

1) gcc -ggdb -o (output file name) (source_ code_file_name.c)
if it compiles without error then
type on $ prompt
2) $ gdb your output file name
you will get message displayed on prompt with last two lines

There is absolutely no warranty for GDB. Type "show warranty" for details.
This GDB was configured as "i386-redhat-linux-gnu"...


3) $b ( or break) line or function number where you want to break


once this is done you can step through your code by hitting "s"
try this if you have any problem let me know I will send you more detail
Helped you I guess

An excellent GDB frontend is
ddd

google for it, and it encapsulates the user from various intricacies of the command line gdb

A useful starting point for GDB, naming also the various front ends used by it.
