    Hi, I also have Sierra, but in my Qt 5.9.1 the compiler has the path: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++

    Maybe try updating your Xcode to 8.3.3 (2 months old)?

    Also, If you open a Terminal and type

    clang++ -v
    

    what does the InstalledDir say...

      Hi and welcome to devnet,

      Did you start Xcode once ? Accept the license agreement ?

        hi, thanks for your reply
        clang++ -v
        output is:-
        Apple LLVM version 8.1.0 (clang-802.0.42)
        Target: x86_64-apple-darwin16.0.0
        Thread model: posix
        InstalledDir: /Applications/Xcode 8.3.2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

        & we are already using Xcode for other applications, develop in IONIC

          Hi, Qt expects the compiler to be installed in /Application/Xcode.app/... that's probably why you get the error. It might work pointing Qt to the correct directory, open a Terminal and type:

          sudo xcode-select -s /Applications/Xcode\ 8.3.2.app/Contents/Developer
          

          If that doesn't work, you could also try creating a symbolic link in /Applications named Xcode.app that points to Xcode\ 8.3.2.app...

                  @Yogikipl Wrong. It is fixed in Qt 5.9.2

                    Hi (if you don't want to wait a couple of weeks for 5.9.2) you can apply the patch yourself, open $HOME/Qt/5.9.1/clang_64/mkspecs/features/toolchain.prf and change line 41 from

                    darwin: cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH
                    

                    to

                    darwin: cxx_flags += -isysroot $$sdk_path_device.value

                      to

                        BUG report says it fixed in that version.

                          @mrjj Release version of 5.9.2 is difficult to download right now, not available in MaintenanceTool yet.

                          @Yogikipl: I tested and could reproduce your bug, when trying to compile the example Qt Quick Controls 2 - Gallery on my Mac. First my fix above wasn't complete, you need the full change (same that's coming in 5.9.2), so change the line (same as before)
                          darwin: cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH
                          to these 5 lines:

                          darwin {
                              uikit:macx-xcode: \
                          	    cxx_flags += -isysroot $$sdk_path_device.value
                              else: \
                          	    cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH
                          }
                          

                          Also it not sufficient just to restart Qt Creator. First, delete your .pro.user file, so you get to reselect the compiler(s) again. Then there's a problem with the caching of files, so try open and close the project a couple of times, to get the "green arrow" lit in Qt Creator and be able to compile.

                                  @hskoglund Hi, we try to replace with

                                  uikit:macx-xcode:

                                  }

                                  & create a new project, & also restart several time, but still there is same error.

                                      @hskoglund Hi, we try to replace with
                                      darwin {
                                      uikit:macx-xcode:
                                      cxx_flags += -isysroot $$sdk_path_device.value
                                      else:
                                      cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH
                                      }

                                      & create a new project, & also restart several time, but still there is same error.

                                      @Yogikipl Did you forget the 2 backslashes? That might explain why you still get the error.
