Thank you for your advice.
1,I have download QT in http://download.qt.io/archive/qt/4.7/qt-... and compile it in Visual Studio 2010 x64 Win64 Command Prompt. But error happens and I can't find demo_shared.lib in my Qt472 folder. So I downloaded another QT in download.qt.io/archive/qt/4.7/qt-win-opensource-4.7.2-vs2008.exe and compile it. Although I enter "..\jom\jom.exe -j 2" error will happens, But I can find demo_shared.lib in my Qt472 folder . And I typing 'qmake --version' on command prompt, I see I am using Qt472 libraries. Although I find demo_shared.lib this time, when I build executable file, VS 2010 remind me "demo_shared.lib::fatal error Module computer class x86 and target computer class x64 conflict "
2,Although qt4.7.2 compile error, I still try to build plugins. But the result is same as using qt 4.8.6. And I download executable file in https://github.com/Vaa3D/release/release... and copy my own plugins to it, when I run executable file, fail instantiation happens as picture.
May be I have some misunderstand about build step. So do you know a way that can build project 100% correct?
