Hi
I use Eclipse to develop a c++ project on winxp.
I compile it for local testing with MinGW g++ in debug mode,
and with Cygwin g++ in release mode cause our target platform is a linux.
It works fine, but there's something strange.
When I set the DEBUG symbol in project properties > C/C++ Paths and Symbols > Symbols and then test a #ifdef DEBUG instruction, i get that DEBUG is undefined.
If I do instead an #ifdef with any "built-in values" like WIN32, WINNT, __cplusplus, i get that they are defined.
I tried with other variable names like _DEBUG or __DEBUG, same, undefined.
So here in my case I use #ifdef WIN32 instead cause i use the win32 build as debug, but is there something I missed to make my own variables work ?

You should use different build configurations for your Debug and Release build. In addition, you should configure the indexer to use the active build configuration (see Preferences->C/C++_>Indexer).

Which language scope did you use (you can have different defines for C, C++ and asm)?
