integrating library causing errors C++ - c++

Question

I am working in a VC++ 2010 windows project that incorporates DirectX SDK (June 2010), and another team generated a physics library to incorporate into the program. When I go through and perform all required calls to the library, and all. and I followed the directions that they gave to integrate the library:
extract the director containing the .h files into my c:\
in C/C++>general>Additional Include Directories place
c:\physics_core // without additional additional dependencies
then in Linker>Input>Additional Dependencies place
C:\physics_core\PhysicsCore\Release\PhysicsCore.lib // without additional additional dependencies
then include the manager, and use the namespace provided wherever the methods, and objects need to be called (intellisence even attempts to suggest auto completes correctly). but then my compiler throws the following list. I am pretty sure that the first 6 have to do with the library itself, and the others have to do with directX.

the thing is when I roll the program back to before I integrate the Physics Library everything works like it is supposed to. the people who created the library tell me that it works fine on all the system(s) they tried to used it on, but they never attempted to use it in a windows program, and they assure me that it is nothing to do with it being a windows application. when I asked if they used any special flags like the first linker warning states they said that they used no such flag (the lead programmer didn't even know what they were, or how to set them). the build before integrating physics had directX working fine even rendering.
any help would be great.
Update: changed the Linker>input>Additional Dependencies to
C:\physics_core\PhysicsCore\Debug\PhysicsCore.lib
may need to change this under release to be the original
that fixed the first 6 errors, but the unresolved externals still exist
Update:
situation solved.
the all errors were solved by taking 2 actions regarding the same properties line.
1 insuring that a debug build of the Library was being used during debug mode.
2 checking the dependencies of the library in question, and including them if there is any overlap. as the compiler first checks the dependencies list of any libraries being used, and then checks the dependencies of the project. if there is any overlap the first one stands, and all those there after are ignored, but if the include dependencies flag is not set to true the compiler will not include them.
so the corrected line to solve the situation was in the Linker>Input>Additional Dependencies needed to be changed to:
C:\physics_core\PhysicsCore\Debug\PhysicsCore.lib // include additional dependencies
again thank you for all your help.

Answer 1

had to modify one of the properties lines in order to clear all errors.
first change was that the directory of the .lib had to be rectified to match that of the build Debug with Debug, and release with release.
the other issues were resolved when the "inherit from parent, or project default" check box in the library Linker was reactivated. (though the direction to incorporate the library said otherwise.
