Using QtCharts with VS2015+Qt VS Tool

diverger

I'm using Qt VS Tools with Qt 5.10.1_32bit. And my project is created with Qt VS Tool, so I have no ways to add "QT += charts" to the .pro file. But I manually add the header includes folder and the library is add to the dependency. Now my application is compiled ok. But when the code runs to "QChart *chart = new QChart;", there is an exception throw in Qt5Gui.dll :

0xC0000005: Access violation reading location 0x00000000.

I can't figure out where is wrong. Must I create .pro using QCreator, and add "QT += charts" to it, then convert it to Qt VS Tool project?

Any help?

@diverger Are you sure it crashes at exactly that location and not somewhere bellow?

Thanks for all your replies.

I finally found the reason. It's similar to @TheTugaOne 's situation. I was compiling the debug version, but linking the non debug version of the Qt5Charts lib. When I link the debug version of Qt5Charts lib, all works well.
