Michael, Sorry, I might have had wrong assumptions about what you want to do. I presume you have a C++ application compiled via Visual Studio 6 that invokes a Haskell DLL. If that's correct, read on; if not, please tell me again what your setting is. To link your Haskell DLL with the C++ application: 1. Create a .def file for your DLL. Say, your Haskell library is HaskellLib.dll, so your .def file will be HaskelLib.def. Suppose the Haskell finction that you want to call from C++ is myHaskellFunc, then the .def file might look like LIBRARY HASKELLLIB EXPORTS myHaskellFunc 2. Create an import library using Visual Studio's lib.exe: lib /DEF:HaskellLib.def /OUT:HaskellLib.lib 3. Add HaskellLib.lib to your Visual Studio project and link. Cheers, Cyril
Cyril,
I know the Haskell Wiki page you pointed to; it does not answer my specific questions.
The decision which compiler to use is not up to me and, as the Wiki page points out, there is no other way to use Haskell modules from within a Visual Studio C++ compiled application than via a DLL:
"The Windows distribution of GHC comes bundled with the GCC compiler, which is used as backend. That's why linking Haskell with Visual C++ is no different from linking GCC-generated code with the code generated by Visual C++.
One cannot statically link together object files produced by those two compilers, but they can be linked dynamically: an executable produced by Visual C++ can invoke a DLL produced by GCC, and vice versa."
