I'm attempting to debug an open-source C++ game on Windows 7 x64, but the debugger windows in Code::Blocks are empty when I debug the program. There's a "CataclysmWin.cbp" file that's included in the repository, but it is configured to use the Linux makefile, so I had to change some settings to get it to work in Windows. This is the .cbp file I'm using.
Here's my build log:

Why isn't debugging working for this project?
Joachim was right - I forgot that the debugging windows don't get populated with info until a break in the code (it has been awhile since I last did this). I put in a breakpoint, the code stopped executing, and the call stack was displayed.
