Creator 2.4RC + Qt 4.8RC + OS X 10.6 + Xcode 4.2 = NO GO



  • I installed the RC versions of the latest Creator 2.4 and Qt 4.8 on OS X 10.6.8 with Xcode 4.2. Now none of the project builds. It looks like some misconfig on the header search paths:

    The compiler can not find its own stdarg.h? Strange.



  • Here too, but with Qt 4.8 release, + os x 10.6.8 + xcode 4.2.1



  • Having the same problem now. Has anyone of you solved this problem or filed a bug as reference?

    Edit: using the current binary versions of the Qt library and Creator from the download section.



  • I've got a bad feeling about the compiler delivered by Apple. If i try a simple hello world from a terminal window, it breaks:
    @
    #include <iostream>

    int main()
    {
    std::cout << "Hello, world!" << std:endl;
    return 0;
    }@

    The output depends the compiler used (Xcode 3.2 = gcc, Xcode4.2 = llvm) but the bottom line is that it can not find the standard c++ library.
    If even that does not work I guess QtCreator has a very small chance to suceed :-/



  • Works in Xcode though. Does anyone know the command line parameters?



  • No touchdown yet but one step further.

    Since compiling of "hello word" works with Xcode I looked at the compiler switches that Apple uses. Then I tried to rebuild that manually and it worked for me
    @g++ -x c++ -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch x86_64 hello_world.cpp@

    The magic seems to be in the @-isysroot /Developer/SDKs/MacOSX10.6.sdk@

    statement.

    Added that to the .pro file

    @QMAKE_CXXFLAGS_DEBUG += -isysroot /Developer/SDKs/MacOSX10.6.sdk@

    and compiling gets way further but still runs into errors

    And that's another dead end for me. Any ideas anybody?
    (To get that straight: it works on OSX Lion and current Xcode without any modifications but I can not update this machine here and the OSX 10.6.* version should still be supported)



  • Adding

    @QMAKE_CXXFLAGS_DEBUG += -isysroot /Developer/SDKs/MacOSX10.6.sdk
    QMAKE_CFLAGS_DEBUG += -mmacosx-version-min=10.6
    QMAKE_LFLAGS_DEBUG += -mmacosx-version-min=10.6@

    to my .pro file helped me to successfully compile a simple Qt project with QtCreator on OSX 10.6.8 and Xcode4.2.

    I gues for the release version I will need the respective variables.
