Qt Creator won't stop at breakpoints

sierdzio

Are you building in Debug mode? If you compile in release, debugger has no symbols to catch on runtime.

Just to make sure I'm doing the right thing, how do I build in Debug mode?

What I'm currently doing is:

Clean All
Rebuild All

Then, with the Project set to Debug (the fourth button from the bottom in the lower left corner), I click on the Debug button (the second button from the bottom in the lower left corner).

Good steps but in wrong order :)

Set Project to Debug mode (Projects pane on the left, or fourth icon from the bottom, as you already wrote).

Clean All.

Rebuild All / Run Debugger (second icon from the bottom or F5).

I also have the same problem. Now I install gdb from macports and (it seems) all works. I cannot say exactly yes, because I not use qt creator too often now. But kind of it works. The two things:

You must sign your new gdb with codesign using self-created code certificate (create it using key chain application)
You must edit /usr/bin/gdb script to make it to call your new gdb instead old one.

I tried what suggested by sierdzio above however the program is still not stopping at the breakpoint.

Any other suggestions?

Try my method - replace gdb from XCode to gdb from macports.

Two things make me a bit reluctant to try your method:

New Qt Creator projects debug properly, which makes me thing it's something to do with the particular project I'm trying to debug.
Will installing a different gdb affect the working of Xcode?

Just a bit more on this problem - I checked the sizes of the two executables and they're identical - shouldn't the debug version be bigger?

Also, the two paths are:

/Users/chris/Desktop/pencil2d-code/debug shadow build/release

/Users/chris/Desktop/pencil2d-code/release shadow build/release

Does the fact that both paths put the executable in a "release" folder indicate anything?

Yes, debugging must me bigger and noticeably bigger. For example write simplest Hello World in usual C and compile it with and without -g flag. If you have the same executable sizes, this means that you have wrong settings. Check qmake flags for debugging target. It must be some like this:
qmake /Users/eugenk/Projects/QT/qt-creator-2.6.1-src/qtcreator.pro -r -spec macx-g++ CONFIG+=debug CONFIG+=x86_64 CONFIG+=declarative_debug CONFIG+=qml_debug

I have same problem, I solved it with the following configuration the .pro

CONFIG -= app_bundle
