LINUX newbie debugging question

I managed to compile my project on Ubuntu 8.10 and would now like to try to debug the ALSA part of JUCE because it doesn’t work here. But I failed to debug it 'til now. I also failed to debug the JUCE Demo. I am using KDevelop, am setting my breakpoint, start the debugger with as-to-debug-file the JUCE Demo, but nothing happens :frowning: What am I doing wrong? Ofcourse I compiled in Debug Config.
