Problems using libglademm under MSVC_2003.NET when building dll

Hi there

I built all my own libraries for libglademm and gtkmm (2.4.5).
I have a perfectly working application using gtkmm and libglademm. The
problem
is that I need to use it as a dll. I'm using static libraries for
everything
except sigc which is dll. (This is what the supplied workspace is set
to)

As soon as I change the project setting from windows application (or
console app, 
both work) to dll, I get the following linking errors:

Any ideas would be appreciated!
Thanks
