Hi Dieter, The command line is order sensitive. You have the order backwards. Put your .o files before the -l<lib> files. Otherwise, the linker says* "Here I have libmyclass.lib, what missing symbols do I need out of there? Hey, I don't have any missing symbols at the moment, I don't need to incorporate anything from libmyclass.lib." Also, you don't need the -I<dir> for doing the linking operation. Doesn't hurt, either. Just clutter. HTH, --Eljay * Don't anthropomorphize linkers. They hate it when you do that.
