libgmp and libffi are external libraries not associated with
Haskell, so I don't think -static (which is for Haskell libraries)
applies to them. You'll have the same problem with any other
sort of library of this type, like libdl and friends ;-)

Dear all,
on our last meeting, we decided to set up a doodle poll to determine the
date of our December's get-together:

There are also new dates available for next year's meetings (with

Hi.
I grew up tired of counting milliseconds, so I wrote a small library[1]
that allows me to specify time units for timeouts and convert between
them. The library also provides wrapped versions of 'timeout' and
'threadDelay' functions:
threadDelay $ 1 # Minute + 30 # Second
Nanosecond
Dear Cafe,
I’m trying to exploit list fusion as provided by GHC (build/foldr). One
function that I want to get fusable is this, it splits a list of
integeres into maximal monotonous subsequences:
streaks :: [Integer] - [[Integer]]
streaks [] = []
streaks (x:xs) = let (this,rest) = oneStreak
Hi,

Now I’d like to implement streaks in terms of build and foldr such that
it is subject to list fusion.
one half of the task is quite doable:
streaks' :: [Integer] - [[Integer]]
streaks' xs = foldr streaksF

Hello there,
Netwire 3.0.0 is out:

Overview
Netwire is a library for high performance functional reactive
programming, which calls its signal functions 'wires'. It solves the
classic problems of FRP through a number of simple concepts:

Please note that when we build with in-tree GMP, we statically link it into
libHSinteger-GMP.a. Also, again only with in-tree, we patch it first to use
our allocator. Both of these things are to make life easier for users creating
hybrid Haskell/C executables who need to use GMP from the C

Debug.Trace, with some short helpers
so
dbg x= x
displays the value of x, provided x is in Show
import Debug.Trace
dbg msg x = dbgsh show msg x

Hi,
When my program starts it needs to know a complete path to the directory
from which it was invoked.
In terms of standard shell (sh) I need the Haskell function that will do
equivalent to:
#!/bin/sh
path=$(dirname $0)
How to get this path in Haskell?
getProgName :: IO String
defined
Yes.

How to get this path in Haskell?
If I understand you correctly, you want
takeDirectory `fmap` getProgName
I think getProgName does not give you the full path, but only the
program name.

To be precise, $0 always contains the path to the program called. You are
right, this path will change depending on location from which the program
was called. So $0 is OK for my case, while current directory is unrelated.
Try this:
#!/bin/sh
echo Arg 0: $0
echo All Parameters: [$@]
Again,
Is the list the right place to ask about this?
I was trying to access Hackage today too, and didn't know who to let know

The 'could not create compact unwind' message is a known (and still
outstanding) linking issue on OS X. It should be harmless - it refers
to the fact that OS X 10.6 uses compact unwind info for exceptions
instead of DWARF unwind information, when possible. The exact cause
isn't (yet) known.
