I am going to ask this question, and then answer it myself. I know this is a newbie question, but since it took me approx. two days to find the right answer, I will send it anyway.
So much for failures - this one is dedicated to all of you newbies:
I went to the MFC project in VS 2010, and I needed to add some third-party static library. Everything went well, both projects were compiled, and my project managed to access the library. Then, when I included some header file from the library in my project, I got a lot of warnings about linkers, about functions in the C runtime library, for example:
Warning 9 warning LNK4006: _sprintf is already defined in libcmtd.lib (sprintf.obj); the second definition is ignored. C: path \ to \ my \ project \ MSVCRTD.lib (MSVCR100D.dll)
I think, “hell”, I tried to launch my project, and it started until I came across a line of code that I tried to write to some file using “fostream”, and then it crashed with some terrible heap exception.
Searching SO, I ran into some related issues, none of which exactly matched my problem:
I almost wrapped the external library in the dll before I came across an answer.
