      Hi,

      I think that you need to add some #include in your sources.
      DO you see some message related to your source files?

      Once your problem is solved don't forget to:

      • Mark the thread as SOLVED using the Topic Tool menu
      • Vote up the answer(s) that helped you to solve the issue

        This might actually be a different problem, but in any case.

        There is some bug in Qt 5.5 and OSX. Fixed in 5.5.1.

        See the mailing list for more information.

          @Huulivoide it's not the same problem, the one from the mailing list is about a warning storm, here those are errors

                Those errors are all about C++11 constructs. You probably have some config in your .pro file trying to force an older C++ standard.
                Like removing C++11 or forcing stdlibc++ instead of libc++.

                  Hi had a very similar problem when I moved my code from Qt 5.3 to 5.4; sometimes some #include are removed from Qt header files and the is needed to add in our code.

                  Last question: "Are you compiling using C++11"??

                    we are having the same issue on our build server (and yet different errors on the Windows side), and are indeed compiling with C++11. I have QMAKE_CXXFLAGS += -std=c++11 in the .pro file. Is that no longer correct/necessary?

                      Now you can use

                      CONFIG += c++11

                        thanks. That resolved the C++11 errors (and should work for you as well @freddy311082 ). I've got a few other std-related things that didn't appear with the previous version, so I will post back if these seem to be core-related vs. necessary changes in our own code.

                        I do have the hundreds of clang diagnostic ignored "-Winconsistent-missing-override" now :)
