linux - How to debug a C program

Question

I am using Linux, GCC and C.

I have a make file.

I want to debug my module. I don't want to debug a single file, I want to debug the whole module.

How can I do it?

Answer 1

Compile your code with the -g flag, and then use the gdb debugger. Documentation for gdb is here, but in essence:

gcc -g -o prog myfile.c another.c

and then:

gdb prog

If you want a user-friendly GUI for gdb, take a look at DDD or Insight.
