      Hi,

      Which version of Xcode are you using ? What parameter did you pass to configure ?

        With XCode 7.0.1 gives this error. After update to XCode 7.3.1, continues with the same. The Mac is OSX El Capitan 10.11.6.

        The same project is compiled (on windows environment) for Windows and Android, and compiles and runs without errors.

        I don't pass any parameter to XCode, is necessary any parameter? When the project is compiled, QT generates the XCode project on the build directory. If opens and compiles on XCode with the XCode project generated, the same error appears .

          Did you build Qt yourself or are you using the official package ?

            The official package.

            The installation is on the default directory (Qt on user directory) and I've selected only these options:

            • Qt \ Qt 5.7 \ iOS
            • Qt \ Tools

            After, I've updated the installation and included Qt \ Qt 5.7 \ Sources, but continues with the same error.

              Can you share your .pro file ?

                    I've found it!!!

                    In my project exist a file with the name time.h. The iPhone SDK has another file with the same name that is included on wchar.h (SDKs/iPhoneOS9.3.sdk/usr/include/wchar.h:91) and the compiler tries to compile my file first.

                    After change the file's name, all compile without problems.

                    Thank you very much!
