Hi,

Does anyone know if I can bring a 64-bit (long long or unsigned long
long) value from C-land into Haskell via hsc2hs? #const on such a
value seems to provide only the low 32 bits, at least in my
environment (Haskell Platform 2009.2.0.2 on Windows). I've tried to
create a 64-bit variant of #co

How could it not be?
That is to say, what initial value would make sense for folding (*)

Except that in the binomial theorem, one uses (^) and not (**).
For (^), setting x ^ 0 = 1 is, as far as I'm aware, uncontested.
This is not so: the exponent in the binomial t
Hey everyone,
Just out of curiosity, what work is being done in the data parallel

Hi,
This is still happening with the current DMG on the website, my
solution has been to install GHC from the DMG, then get the source for
Haskell Platform (haskell-platform-2010.1.0.0.tar.gz) and build it
myself.
Cheers,

I don't know about that code, but have had good experiences on two
projects using the DevIL binding library found on hackage [1]. I
tried pngload [2] originally, but that isn't full featured enough for
real use. iirc, stb-image [3] had a similar issue of being too
bare-bones; the haddock comments

Hi Ketil
Particularly to Haskore rather than package importing or Cabal in
general, AbsPitch is not defined in "Haskore" i.e. Henning
Thielemann's extended Haskore.
AbsPitch in Paul Hudak's Haskore (i.e. "haskore-vintage"), it is a
synonym for Int, I believe the replacement is Henning's Haskore i

Hello, cafeers!
Are there OpenSuse repositories with ghc-6.12 maintained? Some months ago I
installed 6.12.1 from someone's repository but now it's unavailable.
My system is 11.2 (x86_64). Only ghc*6.10.4-7.1 packages are present.
