"uiSpinBoxOctaves":is not a member of "Ui::barFeaturesSift"

In system window10, I used cmake3.15.1 to compiled this project, and then opened .sln on VS2017. Some issues appeared , how to deal with it quickly?

I have also run into this problem. I temporarily fixed it by commenting all related to the error. But when I run the /bin/imagefeaturedetector, I have an error: Segmentation fault (core dumped)

I have fixed the issue by changing main.cpp a little bit:
`
QApplication app(argc, argv);

WindowMain mainWindow;
mainWindow.show();

// new WindowMain();
return app.exec();

`
Hope it help !

I changed the main.cpp according to your advise, also this program compiled successfully. But when I debug it on VS2017, there is still the same error that "mCurrentFeatureAction = mHarrisAction;" in windowMain.cpp caused exception.
The detail of this exceptioin is that exception raised at 0x00007FFA53F3570A (qt5widgetsd.dll) (in imagefeaturedetector.exe) : 0xC0000005: access conflict occurred while reading position 0xFFFFFFFFFFFFFFFF.
I mouse over the error statement, the object "mHarrisAction" show that no information available and no symbols have been loaded for qt5widgetsd.dll.

Maybe qt5 on windows lacks some package. Actually, I have run on Ubuntu 18.04.
