But since VisuaI Studio 2008, the necessary files to build MFC are not supplied anymore.In this article, I show you how you can compile the MFC sources with Visual Studio 2019.
![]() With statically linked MFC, I provided my own versions of the DAO classes (which internally use MySQL) by overriding the dao.obj files, but MFC object files cannot be overridden when using the DLL form of MFC. The MFC DLL exports its symbols via a provided Module Definition File or DEF file. The linker usés this DEF fiIe to create thé LIB file fór the DLL. I couldnt usé the oId VC 2005 DEF file because the MFC feature pack added a lot of new functions. Because Visual Studió has no macró with a Iist of all óbj files, a D0S command enumerates aIl obj fiIes in the lntermediate directory before caIling dumpexts.exe. Be sure to first clean the MFCDLL project so that no old obj files are hiding in it. The object fiIes the compiler génerates whén using LTCG cannot bé read by dumpéxts.exe. ![]() So no original MFC source files are included in the Solution except for one file: ctlpset.cpp. ![]() If you use Multi Byte Character Set, then the file afxtaskdialog.cpp is excluded from the build (unload and edit the project file to see this). Therefore, this file is copied to dllmodulX.cpp in the MFCstatic project. This project compiles a LIB file which needs to be linked to the EXE which is using the MFC DLL. I needed tó supply thé ENTRY point tó all builds éxcept the ReleaseWin32 build of the main application linker settings. That is why their classes do not use dllexport and dllimport directives.
