The OsiXprSolverInterface was built against XPRESS v12 and v13.  As far as
I know, you're the first to report trying it with XPRESS 2003.  Also, we
are still using the XPRESS v12 API, which is deprecated but should still
work with v2003.

I'm not a Windows developer, but it looks to me like your linker is
failing to find the XPRESS libraries.  Check to make sure that:

(a) the Xpress-Optimizer callable libraries are properly installed, and

(b) the path to the XPRESS libraries is properly set in
COIN/Win/startMsDevStudio.bat.

Then start Visual Studio with that .bat file.  That should set the paths
and load the project files you need.

HTH.  Let us know if not.
