# Unresolved External Symbols - HELP!

Posted on 2004-09-23

I am writting a managed c++ class to be packaged as a DLL for use in other applications (other c++ or VB.NET). I have finnaly got most of the problems resolved, but am having diffulclty tracking down the following errors. I think it is probably just a setting that is missing or set wrong, but am not sure where to find it. It seems related to my math functions from math.h that I used in the program... sqrt(), acos(), tan(), cos(), sin(), ceil().

Thanks to drichards that I have gotten this far!
