Hello, Qt-5.4.0 was built from sources at 10.9 build machine with flag -no-c++11 and in qtbase/mkspecs/macx-clang/qmake.conf was set: QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6
The application does run at 10.6 target but crashes: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000000 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 org.qt-project.QtWidgets 0x0000000100fcb762 0x100fbe000 + 55138 1 org.qt-project.QtWidgets 0x00000001010589f5 QStyleFactory::create(QString const&) + 181 2 org.qt-project.QtWidgets 0x0000000100fec2d2 QApplication::style() + 370 3 org.qt-project.QtWidgets 0x0000000100feb624 QApplicationPrivate::initializ e() + 100 4 org.qt-project.QtWidgets 0x0000000100feb460 QApplicationPrivate::construct() + 96 5 com.mydomain.MyApp 0x000000010000b7b9 main + 41 6 com.mydomain.MyApp 0x0000000100005e74 start + 52 It seems that QStyle returns 0. Should I create some style in advance and pass it to application? Which style could be appropriate for 10.6? Yes, I know that 10.6 is not a supported target for 5.4.0, but any advise or direction would be very much appreciated. Thank you in advance. Regards, Robert
