QtCreator fails on MacOS SDK 11.1

  • I have Qt5 from brew in: /usr/local/Cellar/qt5/5.15.2/bin/

    I use QtCreator 4.12.82.

    I have MacOS Big Sur 11.1 with XCode installed in ls /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk

    When I create a new standard project in QtCreator I get the following error:

    10:35:16: Running steps for project test2...
    10:35:16: Starting: "/usr/local/Cellar/qt/5.15.2/bin/qmake" /Users/joefresna/VideoImageEdit/test2/test2.pro -spec macx-g++ CONFIG+=x86_64 CONFIG+=qtquickcompiler

    The platform SDK has been changed from version 11.0 to version 11.1.
    This requires a fresh build. Please wipe the build directory completely,

    Error while building/deploying project test2 (kit: Qt 5.15)

    10:35:20: Elapsed time: 00:04.

    (Note that even if I delete the build directory I still get the warning about wiping the directory)

    The QtCreator Kit points to the qt installed via brew (indicated above). I tried to change the compilers in QtCreator > Projects > Manage Kits > Kits > Compiler and I tried both GCC and Clang from /usr/bin and from XCode, without success.

    When I type xcodebuild -showsdks, I get:

    iOS SDKs:
        iOS 14.4                        -sdk iphoneos14.4
    iOS Simulator SDKs:
        Simulator - iOS 14.4            -sdk iphonesimulator14.4
    macOS SDKs:

        macOS 11.1                      -sdk macosx11.1

    watchOS Simulator SDKs:
        Simulator - watchOS 7.2         -sdk watchsimulator7.2

    Do you know how to solve this problem?

  • Moderators

    check (generally) for a hidden .qmake.stash file, it does not necessarily live inside your build folder, and delete that

    Thank you so much! This was the solution!! There was a .qmake.stash outside the build folder. Deleting it has solved my issue! Thank you!Thank you!Thank you!Thank you!Thank you!

    @joefresna Just a hint: that was exactly what was mentioned in the output: "Please wipe the build directory completely,
    including any .qmake.stash and .qmake.cache files generated by qmake."
