Qt Creator 3.1.1: no debugger on OSX in Desktop config

[jsshapiro]

I've just installed the 5.3 packages and learned that debugging on OSX (Desktop Qt 5.3.0 clang 64bit) doesn't work. The "Application Output" window simply states that "Debugging has failed".

In the Build and Run kits,the Debugger drop list is entirely greyed out; it's as if the installer couldn't find a native-hosted debugger at all. Yet in the Build and Run Debuggers page, both lldb and gdb have clearly been found.

Before I installed this, I was using QT Creator 3.0.1, and everything was working fine. I just tried to "back down" to that version, and now it can't find a debugger either. And it no longer complains about permission to invoke the debugger.

Anybody have any idea what is going on here?

OK. This is weird. If I clone the default desktop kit and set the debugger to lldb, then debugging works again. This raises the question: why isn't lldb being properly discovered by the install process for us in the default kit? Any chance I have something stale in a .pro file somewhere?

I just ran into the same problem, and thanks for finding and posting a solution. You saved me a lot of time.

Hi,

Sounds like bug, you should check the "bug report system":http://bugreports.qt-project.org to see if it's something known. If not please open a report for it
