No more gdb in XCode console when build for iPhone simulator

Question

Usually I use gdb backtrace to debug my application, but recently I can no longer do it when testing on iPhone simulator. The blue gdb word stops being displayed on console, and nothing happens when I type "bt" or "backtrace". I can still build and debug properly on the device though.

My XCode version is 3.2.3. Is there any way to manually activate the gdb (more importantly the backtrace)?

Answer 1

As Jack points out, the Pause button will manually activate gdb & the back trace, which is what you asked. You may have a bad install -- it happens, sometimes, try deleting your /Developer folder & re-installing. XCode 3.2.3 and the debugger work just fine, I use it several times a day.

In particular, CMD-Y is "build & run with debugger", whereas CMD-R is just "build & run" (no debugger, by default), so make sure you're using CMD-Y.

Aside: An issue I keep running into is, after the app quits, the red-stop-sign icon doesn't recognize that the app has finished, so I have to "stop" it again. I believe this is due to iOS-4's keeping apps running in the background.
