MFC Program (Using MFC in Static Library) Problems

Basic knowledge:

When configuring "Use of MFC" in the project's configuration properties, the options are different: If you select "Use MFC in a shared DLL", the compiled program does not include the MFC library, so the file will be small, but if the program is directly When you move to a machine that has not installed MFC, you may not find the MFC DLL. If you select "Use MFC in a static library", the compiled program directly includes the library that calls the MFC. The file may be It will be bigger, but it can be moved directly to other machines.

Problems encountered:

There was no problem compiling when selecting "Use MFC in shared DLL", but there was a problem with library redefinition when selecting "Use MFC in static library" instead. . .

Solution: (3 steps)

First configure MFC to use MFC in a static library:

Properties-> General-> MFC use, select "Use MFC in static library"

Then, configure the runtime:

Properties-> C / C ++-> Code Generation-> Runtime Library, select "Multithreaded (/ MT)"

Finally, add the two library files nafxcw.lib and libcmt.lib to the additional dependencies: (Note: The library nafxcw.lib must precede the library libcmt.lib, the former is the mfc static link library and the latter is the c runtime library)

Properties-> linker-> input-> additional dependencies, add nafxcw.lib and libcmt.lib

OK! !! !!
