Multi-threaded DLL (/MD) vs Multi-threaded (/MT) [duplicate]

Question

My VC++ MFC solution includes four project.

1. Two project build as DLLs
2. One project build as Static Lib
3. One project build as exe with using above three libraries.

I need to host this application without CLR support in windows XP. so I use configuration Use of MFC as Use MFC in a Static Library in all four project.

So my question is what should be the C++-> Code Genaration Configuration for each project.

Answer 1

Use /MD for all your projects. As is stated in the referenced questions: it is important to be consistent. So: even build your Static Lib using /MD, since it will be used in an /MD executable. When you do this, the linker doesn't try to link two different versions of the Microsoft library (static and dynamic) which resolves the error.
