Inline functions in a .lib

Hi, I''m trying to write a math library, but i can;t get inline functions to work. If, in the header i have this: inline int ToInt(float f); then i get an unresolved external symbol in the app i test my lib with. It works if i take away the "inline" bit, but obviously it won;t be inlined. I know this is because inlien functions only have internal linking, and so the function only exists in the .libs source. Is there a way around this apart from defining the function itself in the header? Its probably something really obvious that i''m missing. Cheers, Steve Steve
