Re: Non-interactive stepping

Thanks! That'll work ok for relatively small programs, so I'll probably
take advantage of it, but I'm still in need of something cleaner for large
programs.  I'm starting to code in Mozilla, a tool like this would be
invaluable for understanding the flow of the code when its running.  I
wouldn't mind hacking GDB to try and get this type of functionality if I
knew where to start.

Thanks,
Christopher

|Here's an ugly hack that gives you line information.
|
|Put the following user-defined command in your .gdbinit file:
|
|define mytrace
|  set height 0
|  b main
|  run
|  while 1
|    step
|  end
|end
|
|Run gdb with "gdb -ann=1 myprog" and type "mytrace" at the prompt
|
|to get something like:
|
|(gdb) mytrace
|Breakpoint 1 at 0x804849f: file myprog.c, line 38.
|
|Breakpoint 1, main () at myprog.c:38

|You might want to re-direct any program output.
