I am transfering an existing multi-project VS2008 solution to VS2010.

After fixing a few C++11-related issues all the projects compiled successfully, but I got lots (a hundred or so) of “unresolved external symbol” linker errors. They all were about functions from one of my projects (a library). I’ve checked project dependencies and they were ok: all the users of this library listed it as a dependency.

Before transfer, the solution was succesfully compiling and linking in VS2008.

Why did this issue occur and how to fix it?
