Try this 


start you program under GDB 
define mytrace
   set height 0
   b main
   run
   while 1
      step
   end
end

type mytrace at the gdb prompt

Subject: Is this possible with gdb?


Hi all,

Sorry if this question came up early before but a Google search didn't
result 
in much answer. What I want to do is to see currently executed line to be 
printed on console while using gdb.

Say I got this in foo.cpp

int main()
{
	i=2;
	return 0;
}

compiled into foo and I want gdb to print 

foo.cpp: line 3 
foo.cpp line 4
<exit>

So I just want to see porgram flow. Is this possible with gdb or can anyone 
suggest any other solution?

Any help is grealy appreciated.

Regards,
ismail

Only traces main() part but the interesting stuff happens in threads :( . Any 
way to get it to trace all parts including threads?

The line problematic is one exec() call after that I don't see any line 
printed.

No I can't use this as the program is threaded and I need to do some input 
from the gui thread. ( KDE/Qt app )

Check out http://ltp.sourceforge.net/coverage/lcov.php, this might be what
you are looking for.

GDB is not a code coverage tool. You could look into use gcov.

However, with GDB you can step through your program. Try this,
gdb ./foo

b main
r
n
n
n
n

If you like what you see, try reading the manual.
