This "-lprog1" is working fine if my library is a static library file..
that is if my library is prog1.lib it is working fine.
but if it is prog1.dll it is not working..
plz help..

You'll need the .lib also in case of a dynamic library. Fix your exports in case you're not getting one when you build the library.
