Question

i am using gcc 4.4.3 on ubuntu 10.4 32bit machine.
i use ‘gdb’ to debug my code. Since few days i am seeing that whenever i debug code gdb steps into the c library functions used in the code also(like printf,fgets etc). This shows a long list of calls from one function to other.see the attached screen shot.
Previously gdb was working fine just stepping over my own code.
Maybe i am being novice !! But it is sometimes really irritating when gdb shows me numerous lines which i am not interested in the present context.

If someone can guide me as in how to turn off/on this feature and what can be cause of it being switched on on its own(i don’t remember doing anything).
Many thanks.

Answer 1

i used to do that previously also but then it never went into any of the lib functions

You (or someone) have installed libc6-dbg package. Before that, GDB couldn’t step into libc functions, because they didn’t have any debug info. Now they do, and it can.

Either get out of the habit of typing step when you want next, or un-install libc6-dbg.
