I start to get this same error os same application when i switched to XCode6 . With Xcode6, app runs first but then for some reason it starts making this even i did not change main at all. This s with xcode project created with qt creator and just normal qt/c++ /QML app. I did not put any fancy linker optimisations anywhere, I just got Qt5.3.2RC and XCode6 to get app running in ios8.
My fix was simple #ifdef Q_OS_IOS extern "C" int qtmn(int argc, char *argv[]) #else int main(int argc, char *argv[]) #endif Kate On Mon, Sep 15, 2014 at 4:03 PM, Gustavsen Richard < richard.gustav...@digia.com> wrote: > This could happen if you don't create your Xcode project with qmake.
