FFI, DLL Linking, Windows Haskell Platform 2010

[Nabil Alsharif]

Hi Everybody,

So, like every one else on this list, I have a C library that I would
like to access form Haskell. I am in the process of writing a Haskell
interface for the distorm3 disassembler. The library was compiled into
a DLL using MSVC. Because this is the first I've used FFI I'm keeping
it simple and there is only one function I import Ala:

foreign import ccall "distorm.h distorm_version"
	c_distorm_version :: IO (CUInt)

The issue is when I try to compile the library the linker goes haywire:
C:\Users\tantalum\Documents\Research\distorm_test>ghc --make Main.hs
[2 of 2] Compiling Main             ( Main.hs, Main.o )
Linking Main.exe ...
.\Distorm3.o:fake:(.text+0x11b): undefined reference to `distorm_version'
collect2: ld returned 1 exit status

C:\Users\tantalum\Documents\Research\distorm_test>ghc --make Main.hs -l distorm3
Linking Main.exe ...
C:\Program Files (x86)\Haskell Platform\2010.2.0.0\mingw\bin\ld.exe: cannot find
 -lC:\Users\tantalum\AppData\Local\Temp\ghc5976_0\ghc5976_0.o
collect2: ld returned 1 exit status

Any ideas or suggestions? What is that temporary object file for?

Thanks in advance for any help. Hope you all are having a good day.
Nabil Alsharif.
