Hi all
Can someone help me with getting conditionally #defined code blog to
compile using cmake?
My CmakeLists.txt file has: ADD_DEFINITIONS(-DWITH_QGIS) and I have
some code blocks in .h and .cpp that conditionally compile based on
this e.g.
#ifdef WITH_QGIS
foo...
#endif
The problem I have is that only the ifdefs in the .cpp are properly
being entered into & compiled, while in the .h the code is skipped. My
theory is this is because the -DWITH_QGIS is not being passed along to
MOC when it is run on the header file.
87 #ifdef WITH_QGIS
88 void zoomInMode();
89 void zoomOutMode();
etc...
99 #endif
If I comment out the ifdef, MOC runs and my Qt slots work properly.
Has anyone encountered a similar issue? I am using cmake version
2.4-patch 5 on ubuntu feisty. When compiled with qmake the same code
works fine so I am thinking this is coming back to the way that cmake
is calling moc?
Many thanks!
I've been looking into to the code and the preprocessor definitions is
missing
Add this code after QT4_GET_MOC_INC_DIRS(moc_includes) to the macro
QT4_WRAP_CPP (FinfQt4.cmake) and see if it works:
GET_DIRECTORY_PROPERTY(_flags DEFINITIONS)
SEPARATE_ARGUMENTS(_flags)
LIST(APPEND moc_includes ${_flags})
I didn't test
