We tried to build cocos2d-x on Windows with VS2015 Update 3. It failed to build on x64 due to the error C2065: 'GWL_WNDPROC': undeclared identifier. 'GWL_WNDPROC' is defined in C:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0\...
One issue however that has me stumped is this error from the subject line. Somehow it doesn't seem to be able to find GWL_USERDATA (the same happens with GWL_WNDPROC btw), however, when hovering the mouse over these defines, they come up in the tooltip just fine....
当我们创建一个窗口时,我们通常的做法是通过 SetWindowLong(hwnd, GWL_USERDATA, this) 将 this 放在窗口的用户数据区域中,这样我们就可以进行类似MFC的回调或紧密集成的 WndProc 。问题是这不适用于Win64,因为LONG只有32位宽。什么是解决这个问题的更好的解决方案适用于32位和64位系统?

However, in MSDN Library's entry for SetWindowLongPtr, it does not specify this restriction next to GWLP_WNDPROC. In MSDN Library, it says GetWindowLongPointer and its constants are declared in WinUser.h, however, after opening WinUser.h and looking for the Declarations, I was unable to fin...
