I work on Mac OS 10.8.5 and Qt 5.1.1 with among other things, qdebug class which work well with some projects and doesn't compile with some others. I've already tried to re-install Qt which didn't change a thing.
It is certainly due to the use of SDL library (?!) but it used to work fine. Here's a part of the compilation output :
In file included from ../../Stage/Joker/tests/SDLTest/main.cpp:7:
In file included from /Applications/QT/5.1.1/clang_64/include/QtCore/QDebug:1:
In file included from /Applications/QT/5.1.1/clang_64/include/QtCore/qdebug.h:46:
In file included from /Library/Frameworks/QtCore.framework/Headers/qhash.h:46:
/Library/Frameworks/QtCore.framework/Headers/qchar.h:76:5: error: unknown type name 'QT_ASCII_CAST_WARN_CONSTRUCTOR'
QT_ASCII_CAST_WARN_CONSTRUCTOR QChar(char c);
^
If needed, I can provide more output or unworking Qt classes.
I build my code with Qt => Build => Run Unfortunatly, I'm unable to reproduce the code on an other computer.
Here's the pro file (which work well with all my co-workers, except me) :
TEMPLATE = app
SOURCES += main.cpp
OBJECTIVE_HEADERS += ../../libs/PhGraphic/SDLMain.h
OBJECTIVE_SOURCES += ../../libs/PhGraphic/SDLMain.m
LIBS += -framework Cocoa
QMAKE_CXXFLAGS += -F/Library/Frameworks
QMAKE_OBJECTIVE_CFLAGS += -F/Library/Frameworks
LIBS += -F/Library/Frameworks
LIBS += -framework SDL -framework SDL_image -framework SDL_ttf
I'd once had this problem after installing a software: it created a QtCore.framework in the /Library/Framework folder that overrided the QtCore of your current Qt kit (due to QMAKE_CXXFLAGS += -F/Library/Frameworks).
