In Visual Studio (C++ Express 2008) I can set pre-processor definitions by going to:
Project Settings - C/C++ - Preprocessor
and add them to Preprocessor definitions which I can then use in #ifdef statements in my code. This is useful to seperate out code for debug and release builds.
I'm struggling how to do this in QtCreator. I've tried putting the preprocessor definitions in:
Projects - Build Steps - QMake - Details - Additional Arguments
but they never get picked up in the #ifdef.
I've also tried doing this in the project .pro file which also doesn't work for me:
DEFINES += MY_BUILD_DEBUG
DEFINES += MY_BUILD_RELEASE
The strange thing here is that in the release build, the debugging output is 'debug, debug|release' only but the MY_BUILD_RELEASE definition is there since it picks it up in the #ifdef.
It's as if the DEFINES are added regardless of the build configuration, which is what I thought the CONFIG and braces was for.
