Hi, so there are different regions libraries?
Is there a shootout comparing them, possibly also with ResourceT from
conduit (which has also been implemented in a stand-alone package
http://hackage.haskell.org/package/resource-simple-0.1 by Robin Banks), for

I suppose you need to specify addrSocketType (usually Stream or
Datagram) for defaultHints.
Although it seems it is not required on recent versions of FreeBSD (= 8.x?),
I think it is better to specify addrSocketType always.

Hello,
Does any one knows of an Haskell compiler targeting the JVM ? And of one
targeting the .Net virtual machine ?

Thank you. I have specified addrSocketType. And now it works.

The UHC can compile to JVM[1, 2], but the backend is far from production-ready.
Also, I don't believe anyone is working on the backend currently.

There are some substantial technical challenges:

Not that it can't be done, but there's nothing ready yet.

A more subtle issue is that there's some sort of memory leak that arises
when you can't instruct the GC to follow projection functions of data

Looking at IntMap's left-biased 'union' function [1], I noticed that the
complexity is O(n+m) where n is the size of the left map, and m is the size
of the right map.

LLVM has a .net and JVM code generator. I don't think it is production ready
yet. GHC can generate code via LLVM. So in theory one could run on either VM.
However, see the Why isn't GHC available ... link below. The GC and library
integration would require lot's of work. Good senior project

I though it might work without it, but I get the error I mentioned:

I posted a minor update to unix-bytestring a few days ago in order to
deal with the Num not implying Eq thing in GHC 7.4, but it looks like
