write the C wrapper that calls haskell, then link that to your C++ objects

I think what you're really asking is how to call C from C++

Hi all,

Well...somehow I'm a beginner in Haskell. But actually my interest in Haskell will increase if it is possible to call a haskell function in C++.
Something like GreenCard ( http://www.haskell.org/greencard/ ) simplifying the task of interfacing Haskell programs to external libraries (usually). But is there also a task to interface a foreign language with Haskell, but calling Haskell functions. Or c2hs which is an interface generator that simplifies the development of Haskell bindings to C libraries.

I want to know this, because in my company some guys are doing some testing with Frotran and MatLab and I want to show them the power of haskell and the software which we are using is implemented in C++ (there is the reason to make Haskel -> C++).

I read somewhere that the only way for C++ calling a haskell function is to create a binding between Haskell and C and from C to C++, but a easy "Hello World" example was not there.
Unfortunatelly I couldn't found anything usefull, like an complete example, or how to compile the code from haskell to C to C++.

Can sombody help me, please :P

Chears,
Miguel Lordelo.
