hslibs/ObjectIO

15 Oct 2001

      Hi all.

I thought I would try compiling the GHC CVS ObjectIO library on NT with GHC
5.02.

Following error messages passed out by the compiler I modified C_util12.lhs
as follows (see attached file):
    - import MarshallAlloc
    - import Ptr instead of Addr
    - Change Addr to Ptr
    - AddrOff changed to Int

and get the following error message in the fpeek function:

$ make
ghc -static -c ../../OSWindows/Cutil_12.hs -fglasgow-exts -syslib
concurrent -syslib
ang -cpp  -i../../CleanStdEnv:../../OSWindows:../../ObjectIO:../../OSWindo
ws/Windows_C_12 -I../../ObjectIO -DMVAR=1

..\\..\\OSWindows\\Cutil_12.hs:34:
    Couldn't match `* -> *' against `Type bx'
        Expected kind: * -> *
        Inferred kind: Type bx
    When checking that `Ptr' is a type
    In the type: forall a. (Storable a) => Ptr -> IO a
    While checking the type signature for `fpeek'
make: *** [../../OSWindows/Cutil_12.o] Error 1

I am stumped on this (I don't know what the stars mean).  My best guess is
that it is something to do with the monomorphism restriction.

Any advice on how to clear this up?

Are the changes I made in keeping with the intention of the original code?

Cheers
