Hi I am having a problem when trying to compile a opencv build for QT using MinGW32. I've followed the instructions on https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows but failed build:
mingw32-make[2]: * [3rdparty/protobuf/CMakeFiles/libprotobuf.dir/src/google/protobuf/stubs/io_win32.cc.obj] Error 1 CMakeFiles\Makefile2:710: recipe for target '3rdparty/protobuf/CMakeFiles/libprotobuf.dir/all' failed mingw32-make[1]: [3rdparty/protobuf/CMakeFiles/libprotobuf.dir/all] Error 2 Makefile:161: recipe for target 'all' failed mingw32-make: ** [all] Error 2
