Pre-processor-defines depending on makefile-targets ?

[Comer352l]

Hi,

I'm searching for a possibility to create pre-processor-defines depending on the called makefile target.
I'm currently using the usual solution for conditional compiling of debug code parts:

#ifdef DEBUG
   ...debug-code
#endif

#ifdef DEBUG
   ...debug-code
#endif

To copy to clipboard, switch view to plain text mode 

At the moment, I set DEBUG in a separate header-file, which I have to include in all souces that contain such debug-sequences.
My idea/intention is to make this separate header-file obsolete. DEBUG should be set when I compile the software with "make debug" (only).

It's a qmake-project and I use CONFIG += debug_and_relase.

I know the DEFINES option, but don't know how to make it depending on the called make target. Does anyone know how to do that ?

Have you tried ?

debug:DEFINES += __MY_DEBUG_DEFINE__
release:DEFINES += __MY_RELEASE_DEFINE__

debug:DEFINES += __MY_DEBUG_DEFINE__
release:DEFINES += __MY_RELEASE_DEFINE__

Thanks for your answer ! Yes, I already tried that but it doesn't work :
Becasue of CONFIG += debug_and_release, always both (__MY_DEBUG_DEFINE__ and __MY_RELEASE_DEFINE__) will be defined. It doesn't matter which makefile-target I call...

I finally solved it:

CONFIG(debug, debug|release) {
     DEFINES = __MY_DEBUG_DEFINE__
} else {
     DEFINES = __MY_RELEASE_DEFINE__
}

CONFIG(debug, debug|release) {
     DEFINES = __MY_DEBUG_DEFINE__
} else {
     DEFINES = __MY_RELEASE_DEFINE__
}

To copy to clipboard, switch view to plain text mode 

I still don't understand CONFIG(...) completely, documentation is really incomplete for stuff like this...
