Zlib.lib

[Shendare]

Sounds like you haven't told Visual C++ where to find zlib.lib.

Check under Tools -> Options -> Projects and Solutions -> VC++ Directories

Under the right-hand drop-down list, choose "Library Files", and make sure your zlib directory (e.g., C:\zlib\lib) is listed in the big list box underneath.

You'll also want to make sure the Include directory is set (e.g. C:\zlib\include).

Also, it doesn't hurt to double check your configured zlib directory and make sure zlib.lib is indeed in the lib folder.
