Question about linking in GHC

Question

Mushy-pea 36 What, you can change this tag?

Hello everyone. I have been using the Haskell compiler GHC 6.6 a bit recently to test some simple programs (for learning purposes). In it's default mode it produces three output files for a given source file: a .exe, a .o and a .hi. The .exe is quite big and I found out elsewhere that's because it contains all the base Haskell runtime functions statically linked. Does anyone know what goes in the .hi file? I've just not used a compiler that produces three output files before, so I'm curious. I would assume the .o is an object file (i.e. contains the instructions generated from your source code).

Steven.

Hi all. This question has been answered in IRC. If you came to this thread from a search engine, see http://www.haskell.org/ghc/docs/latest/html/users_guide/separate-compilation.html for an explanation.
