Preprocessor definition for debug code

[muemart]

Is there a standard preprocessor definition for debug code? I spotted some #ifndef NDEBUGs and #ifdef _DEBUGs, but I don't know if they are platform independent and which one I should use. I'm writing (actually, I'm done) some sort of stack trace for the xml/lua loader, which isn't really necessary for release builds.

Two answers on this question:

1) NDEBUG (for release) and _DEBUG (for debug) both work. They are defined as compiler flags for both MSVC and GCC builds. For example, NDEBUG is used in util/OrxAssert.h

2) Don't use it unless you have really good reasons to disable/enable a feature under certain build conditions. Every #if makes the code harder to test because it means that code that runs in one environment may fail in another. If your code doesn't severly compromise the release build I suggest to enable it for both build settings.

I'll leave the defines out, then. It only needs a few megabytes of memory (strongly depends on how big the file is), and is probably lightning fast compared to the lua code anyway.

people that create mainly content (and no code) for Orxonox may use a release build, so I think it's a good thing to enable this feature for all builds.
