Hello.

Is it is possible to use the results of the system check made by CMake in the C++ preprocessor?

I want to build a class differently according if the KDE version for which the package is build is >=4.2 or not - writing than in the source code something like this:

#ifdef OLDKDE
[special code for libkde 4.0 and 4.1]
#else
[special code for libkde 4.2 or newer - making use of function not yet available in 4.0/4.1]
#endif

Is CMake able to make the results of it's system check available to the preprocessor in some way - or to do something similar?

Regards.

Tim

You could include kdeversion.h and use KDE_IS_VERSION

for example

Code: Select all

#if KDE_IS_VERSION(4,1,0)
//code for 4.1.0 or later
#else
// code for earlier versions
#endif


Cheers,

Thanks, that's working fine.

(By the way - for other users interested in this question: http://api.kde.org/4.x-api/kdelibs-apid ... 11efe3b015 has the documentation.)
