Updated to Xcode 6.01, now my qt project has #include errors



  • I just finished upgrading to XCode 6.01. And tried to recompile my Qt Creator project. I am getting this error:

    @/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/iosfwd:90: error: 'wchar.h' file not found
    #include <wchar.h> // for mbstate_t
    ^@

    I'm guessing some include files were moved in Xcode 6.01. Wonder if anyone has any advice how fix this?

    Hi,

    Did you do a full clean rebuild ?



  • Yes. It crashes right at the beginning. I see there is a new version of Qt Creator. I'm going to install it.



  • I found the answer in stack overflow, but when I pasted the link here I did something wrong. The gist of the answer was this:

    Find qdevice.pri in you Qt install directory:

    /users/nic/Qt/5.3/clang_64/mkspecs/qdevice.pri

    and change the line

    @!host_build:QMAKE_MAC_SDK = macosx10.8@

    to

    @!host_build:QMAKE_MAC_SDK = macosx10.9@



  • wchar.h is a system header file located at /usr/include/wchar.h (or SDK/usr/include/wchar.h). It doesn't appear to have moved since Mac OS X 10.4 (oldest SDK I can find) and is still there in Mac OS X 10.10.

    I have no (compiling) problems with Xcode 6.

    Check your install!



  • My previous post seems to be the root cause of my errors.



  • ah yes, there is no macosx10.8 with Xcode 6



  • The one side effect of doing the change I came up with above is the debugger now fails to launch. Not sure if anyone at Qt has a suggestion to fix Qt Creator to work with OSX 10.9?



  • yeah, debugging does not work with Xcode 6. See this thread for a few workarounds:

  • The final fix for this was to rename the 6.01 version of Xcode to XCode6 and reinstall XCode 5.1.1. I had to still screw around with the debugger settings before the debugger fired back up. Quite a pain. But it seems to be working now.

    I am guessing the upcoming release of Qt Creator coming will resolve the XCode 6/OSX changes?
