Link libraries with dependencies in Visual C++ without getting LNK4006

Question

I have a set of statically-compiled libraries, with fairly deep-running dependencies between the libraries. For example, the executable X uses libraries A and B, A uses libr

Answer 1

Poor flodin seems frustrated that nobody will explain how to disable the linker warnings. Well, I've had a similar problem, and for years I have simply lived with the fact that several hundred warnings were displayed. Now, however, thanks to the info from Link /ignore, I figured out how to disable the linker warnings.

I'm using Visual Studio 2008. In Project -> Settings -> Configuration Properties -> Librarian -> Command Line -> Additional Options, I added "/ignore:4006" (without the quotes). Now my warnings are gone!

Answer 2

I think the best course of action here will be to ignore/disable the linker warnings(LNK4006) since C.lib needs to be part of both A.Lib and B.lib and A.Lib does not need to know that B.lib itself uses C.Lib.

The problem is you are not localizing library C's symbols. So you have a ODR violation when you link in A and B. You need to have a way to make these private. By default all symbols are exported. One way to do this is to have a special linker definition file for both A and B that explicitly mention which files need to be exported.
