ghc -c /home/user/file.hs

hello, I installed ok the rpm-packages on linux (Mandrake 8.1), but when I try to compile something the following message appears: f2.hs:1: failed to load interface for `Prelude': Bad interface file: ./Prelude.hi does not exist Action: openFile Reason: No such file or directory File: ./Prelude.hi If I go to the directory /usr/bin (where the binary file ghc is) and I type then the compilation is done without problems. Does anyone know what I have to do for compiling without problems in any folder? (The directory /usr/bin is my PATH).
