Hello,

Sorry if this is a repeat, I didn't see the first one go through...

First, I apologize if this has an obvious solution, I've been banging my head against the wall for days, and just can't get this to work.

I am using the C++ compiler in Visual Studio.NET 2003, it's in a lab that I don't have install priveleges on, so its very difficult to get other environments running.

I am just trying to build a new GEM object. I decided to start simple, and work with the existing color object and just change it slightly to see if I could get it to work. I named my files newcolor.cpp.h and changed all the class names and the function names. The only thing I changed was to switch the order of the color vectors.

First things first, I guess I should make sure I have the right basic idea. I am trying to build a newcolor.dll file which will be in the extra folder (where gem.dll is). Assuming that is correct, I get this series of errors and am unable to resolve them. Any suggestions?

BTW, I have tried building GEM from scratch using Visual Studio and am unable due to errors very similar to the "unresolved external symbol" errors below.

Thanks, Gabe Westmaas
