2 questions regarding ghci and --make

I have just built ghc-5.00.2 and I have 2 questions: 1.- What is the option that I have to change to build the system for interactive use? At this moment, when I run "ghci", I obtain $ ghci ghc-5.00.2: not built for interactive use 2.- If I want to have modules in separate directories. How can I tell "--make" to look for them? For example, imagine that I have the following configuration: DirectoryA contains file A.hs DirectoryB contains file B.hs And I have "Main.hs" which imports "A" and "B". Is there a nice way to compile it? Regards, Jose Labra
