Problem including library (dllimport)

[tbscope]

This is a quess. Without seeing the CyDeviceFinder.h include file I can't be sure.
But try this: #define CYDEVICEFINDER_EXPORTS instead of #define IMAGECOMPOSER_EXPORTS

Now, in reality it might be named differently, check CyDeviceFinder.h

It didnt work

Despite the include I wrote is for CyDeviceFinder.h , the error seems to come from another file..

I include DeviceFinder, but that ones includes CyConfig, that one CyPersistentRepository and at last CyParameterRepository

I tried to write the define line in CyPersistentRepository like

#define CYPERSISTENTREPOSITORY_EXPORTS
and also
#define CYPARAMETERREPOSITORY_EXPORTS

but still doesnt work....

I have no idea then.
Did you check the documentation of the library you're using?

Yes, i checked, they use Visual Studio to make it work.... could it have something to do with this problem?

I'm trying now with Visual Studio Express and it seems to work, how is it possible that it works on VS and not in QT, arent the libraries independent from the Development environment?
