You need to set a compiler flag for that.

To do it, Get Info on the target, make sure you have selected the Debug configuration (and not All Configurations), and look for Other C Flags and Other C++ Flags (in Xcode 3.1 these are under GCC 4.2 - Language).

Then add the following as a value: -DDEBUG for both.

This will define the DEBUG for the precompiler to pick it up.

project -> settings -> c/c++ (or code generation?) look for a text box labeled Preprocessor Definitions and just add DEBUG to the end of the comment separated list.
