We have used the g++-2 compiler that you can get with Cygwin
and it seems to work fine. (mingw-g++ and the normal g++ did
not work for us.)
Another hint: maybe you should give -lstdc++ as a flag to
the final linking fase.
A final
paths which the mingwin g++ did not understand
but that was easily fixed by replacing mingwin's g++ by a
script that first converts all its arguments which look like
filenames to windows-paths and then calls mingwin's g++.
Anyway, thanks for everyone's suggestions!

Dear GHC users,
I have the following problem and I wonder if anyone can
help.
I am using the FFI to talk to a library of functions
written in C++.
On Unixes (Solaris, Linux) this works just fine if one adds
the right -ldstdc++ here and there.
However, I am using Cygwin now and that is where

it is a general fix, since Hugs seems to suffer
from exactly the same problem...)

It is nice to show the difference. What I am looking for

One solution might be
Hi,
I want to use the functions:
hGetBufBA :: Handle - MutableByteArray RealWorld a - Int - IO Int
hPutBufBA :: Handle - MutableByteArray RealWorld a - Int - IO ()
But as soon as I mention their types, 'RealWorld' is not in
scope. In what module is this defined?

the Select module.
Has anybody had this problem before, and, if so, what could
be a solution?
Thanks,

Hi,
I recently started experimenting using the FFI in GHC and
GHCi.
In GHCi, one would like to press control-C in the middle of
a computation, and get back to the prompt.
It is however hard to understand how control-C and the
foreign function calls interact.
I noticed that GHCi does not react
