These are just a few of the errors but there were 223 error(s), 1635 warning(s)

Can anyone please help me? Ive been looking at this for 2days now and still dont have the right solution how to get rid of them.

Thanks!

Somehow, you're not linking with the C++ runtime library.

Thanks for your reply!

I ignored the c++ runtime library because I am getting these kind of errors:

You should set the same runtime library settings for all your libraries and the main app. If you're using Visual Studio versions 2002-2010, check options: C++->Code Generation->Runtime Library

They were already set to Multi-threaded Debug (/MTd) :(

I am using VS2005.

Can you check the linker options to make sure the defaults still apply to all libs and the app.

Can you also check release.

Do a full rebuild on both.

Hi,

Here is the linker options in debug configuration.

I already made a full rebuild on it many times. :(

That looks fine to me.

Did you double check the linker settings on the library?

The linker's unhappy with files AppVersion, AppRecovery ... Are these in the library or program? Is the library a DLL or static?
