(a) The lib is not attached (but don't bother, I don't open attachments
     anyway).

(b) If you don't post the code that _uses_ that library, what use to post
     the library and the header?

Create another project where you'll use the code from your library, only
not as a library, but directly: add all the source files from your library
to the same project. Everything else should be the same. If it compiles
and links, then you got a problem setting the other project up. If it
does not compile and/or link, the problem is in the code, so make sure it
builds correctly before you attempt using your "whole dang project" as
a library again.
