[Haskell] C++ bindings

[Wolfgang Jeltsch]

Hello,

what are good approaches for creating Haskell bindings to C++ libraries?  The 
most promising so far seems to create C wrappers around the C++ libraries and 
then bind to them.  Is it feasible to bind directly to C++ using ccall by 
relying on some standardized C++ ABI?  What about H/Direct?  Are there any 
other good ways?

Thank you for any hints.

Best wishes,
Wolfgang
