Hi! Here's a letter from someone who has next to no clue about what he is doing so have patience and don't assume any knowledge when answering... I'm trying to create a package for ghc. I've struggled quite a lot and gotten this far: (This is when invoking ghci -package yahu) Loading package base ... linking ... done. Loading package yahu ... linking ... /.../chalmers.se/fs/cab/cs/work/proj/multi/pub/lib/yahu/Yahu/YahuHaskell.o: unknown symbol `__stginit_List_' ghc-6.0.1: panic! (the `impossible' happened, GHC version 6.0.1): can't load package `yahu' I'm surprised by this. Why do I get this error message? From the name of the symbol I would expect that it can be found in package base but aparently not... Please advice. /Josef
