How to debug gcc in Linux

I'm using gcc in Linux to compile my program. Is there a way to step
through the code in some kind of debugger mode? Thanks.

Learn all about 'gdb'. It provides stepping, breakpoints, and
post-mortem debugging.

In addition to "learn gdb" comment, please note that you selected
particularly bad subject for your post: the task that you want to
perform -- debug your own code (the compiler you used to compile
that code is mostly irrelevant) -- has absolutely nothing to do
with debugging gcc (the compiler itself) on Linux.

compile your code with -g flag,
gcc -g project.c -o project

the -g flag produces debug informations on the binary, which is
especially usable for gdb. You can also use some additional flags to
produce debug information in other formats.

After the compilition open the binary with gdb.
gdb project
you'll get a subshell, for the most important commandos on this subshell
(run, break, step, where etc.) pleas read the help. There're also some
GUI tools, ddd i.E. is a nice frontend for gdb.

Have fun
cheers
