--- Comment #2 from Nikita Sirgienko <warqu...@gmail.com> --- Could you please go to build directory, open CMakeCache.txt and check that variables QMAKE_EXECUTABLE and Qt5*_DIR point to system qt? Also could you find your qdialogbuttonbox.h (for example, my path /usr/include/x86_64-linux-gnu/qt5/QtWidgets/qdialogbuttonbox.h) and mannually check that signals ::rejected and ::accepted. If the signals and cmake use proper system qt, that will means, what your qt broken from June 1, for example, by update. -- You are receiving this mail because: You are watching all bug changes.
