No, it means that the HTTP package has no upper bound on its dependency on the
network package, and the type of Network.URI.relativeTo changed in
network-2.4.0.0 versus network-2.3.*
You can try either
cabal install --constraint="HTTP >= 4000.2.5" cabal-install
or
cabal install --constraint="network < 2.4" cabal-install
Either way, check with the --dry-run flag first whether cabal reports any
problems.

Subject: [Haskell-beginners] graphical output?
Message-ID: <[email protected]>
Content-Type: text/plain; charset=UTF-8; format=flowed
How might I (easily) use Haskell to draw simple 2D graphics?
Outputting a SVG file is OK for simple static results, but I want to animate.
(Windows platform is strongly preferred.)

I suggest checking out 'gloss':
http://hackage.haskell.org/package/gloss
It's based on OpenGL, which comes with the Haskell Platform, and has a
simple interface for making animations.

Hmm, is there any tutorial or friendly guide to Gloss?

Not exactly a guide, but you might get some mileage out of
> cabal install gloss-examples
(note for some reason I had to install llvm first).

Thanks Karl
I did try the download several times.
'Unknown' and 'Unknown-1' are 2 separate downloads.
$ openssl sha1 /Users/henrylockyer/Downloads/Unknown-1
SHA1(/Users/henrylockyer/Downloads/Unknown-1)=
89e6fb747816af69acabc5c04cee103257855614
$ openssl sha1 /Users/henrylockyer/Downloads/Unknown
SHA1(/Users/henrylockyer/Downloads/Unknown)=
89e6fb747816af69acabc5c04cee103257855614
Both have the same checkum as published on the download page...
SHA-1: 89e6fb747816af69acabc5c04cee103257855614

Mmm. clicking the download link does not work but ctrl-click and 'download
linked file...' to the desktop now seems to have worked and it is recognised as
a package...
