How do I check the current line number that I'm stopped in when debugging with GDB? I would have thought this would be obvious (and maybe it is) but I don't see it on the GDB Cheat Sheet.

Some digging around revealed the following methods:

  1. frame: This command was exactly what I was looking for. Output looked as follows: 

    (gdb) frame
#0  MyDialog::on_saveButton_clicked (this=0x72bf9e0) at src/ui/dialog/MyDialog.cxx:86
86          _item->save();
(gdb)

  2. where or bt (same effect): This prints out the call stack, ending on the current line.

  3. list *$pc: This doesn't tell you the exact line but it prints out the surrounding lines with the current line in the center.

    I know you mention GDB but just as a suggestion have you tried using gdbtui? It has a nice terminal GUI that let's you see the current and surround lines. You can also scroll up down using the keyboard directional keys. – Nobilis May 21 '13 at 03:12
  • @Nobilis Thanks for the tip! gdbtui looks pretty sweet! – Freedom_Ben May 21 '13 at 04:12
