'undefined reference to `_imp__Addr_zdfNumAddrOff_closure' (?????????)

[Heron]

Hello,   I am using GHC  4.08.1 on Win32. Every attempt to compile the code below results in a message error on link phase. The message is shown after the code.   teste.hs ------------------------------------------------------------ Module Main(main) where   import GlaExts import Storable import Addr   main :: IO Addr main = malloc 0 >>= \addr ->        return (f addr)        f :: Addr -> Addr f addr = addr `plusAddr` (fromIntegral 1) -------------------------------------------------------------     ERROR MESSAGE WHEN LINKING:   teste.o(.text+0x4c):fake: undefined reference to `_imp__Addr_zdfNumAddrOff_closure' teste.o(.text+0xaf):fake: undefined reference to `_imp__Addr_zdfNumAddrOff_closure' -----------------------------------------------------------   Originally, I detected this error when using the pointer arithmetic operations povided by Addr library. The code is only for present the error. It has no real meaning ... but I think it is correct.   Can you help me to solve this problem, please ? :-)   Heron
