I have a Visual studio 2005 solution that has two projects. One is a static library and the other is a executable used to test the features in the static library. The static library uses MFC. I got the following errors when I built the solution. uafxcwd.lib(afxmem.obj) : error LNK2005: "void * __cdecl operator new(unsigned int)" (??2@YAPAXI@Z) already defined in LIBCMTD.lib(new.obj) uafxcwd.lib(afxmem.obj) : error LNK2005: "void __cdecl operator delete(void *)" (?? 3@YAXPAX@Z) already defined in LIBCMTD.lib(dbgdel.obj) uafxcwd.lib(afxmem.obj) : error LNK2005: "void * __cdecl operator new[]
