I've just create it:

StackInterpreterMacOSConfig subclass: #StackInterpreterDebugMacOSConfig
    instanceVariableNames: ''
    classVariableNames: ''
    poolDictionaries: ''
    category: 'CMakeVMMaker'

And implemented:

StackInterpreterDebugMacOSConfig >> compilerFlags

    ^ self commonCompilerFlags, ' ' ,self compilerFlagsDebug

Is this correct ? I would like to complelty debug with XCode out of the box.

Thanks

Mariano
