Okay. Then I assume you also compiled the three example program that are 
included in lapackpp.vcproj? These obviously linked without this linker 
error, so you should try to compare the compiler/linker settings of the 
example programs with the ones of your own program.

First I'd suggest you should check whether the linker actually finds your 
newly compiled version of lapackpp.dll and lapackpp.lib. Well, other than 
that... I don't have MSVC and/or winXP at hand, so I can really only suggest 
you should compare your own program to lapackpp's example program.

We would be glad to hear about the final outcome of your problem.
