推荐答案

有两个设置必须互相一致:

There are two settings that must agree with each other:

(1) Project > Properties > General > Use of MFC
(2) Project > Properties > C/C++ / Code Generation / Runtime Library

如果 (1) 设置为 Use MFC in static library，那么 (2) 必须是 Multithreaded (/MT) 或 Multithreaded Debug (/MTd) (在 Release 和 Debug 版本中，相应地).如果 (1) 是 Use MFC in Shared DLL，那么 (2) 必须是 Multi-threaded DLL (/MD) 或 Multi-threaded Debug DLL (/MDd).

If (1) is set to Use MFC in static library, then (2) must be Multithreaded (/MT) or Multithreaded Debug (/MTd) (in Release and Debug builds, correspondingly). If (1) is Use MFC in Shared DLL, then (2) must be Multi-threaded DLL (/MD) or Multi-threaded Debug DLL (/MDd).

当两者不同意时，你会得到你所显示的错误.

When the two don't agree, you get the error you've shown.
