Thanks, Martijn, glad to hear it's working for you too. I'll see what I can do about cabal+hackage... Uwe On 4/19/09, Martijn van Steenbergen wrote:

It works fine on 6.10.1 on Leopard Intel as well.

I'm afraid I haven't messed with cabal much yet, so it's not cabalized; neither is it uploaded to hackage, as I have no account there. If someone wants to do either of those, please feel entirely free to do so.

It's really easy to do this, and I strongly suggest you do. To save you some work, here's a cabal file you can use that directly allows you to 'cabal install' your package:

(filename: rungekutta.cabal)

...

Name: rungekutta Version: 0.1

Cabal-Version: >= 1.2 Build-Type: Simple License: BSD3 License-File: LICENSE

Library Build-Depends: base < 5 Exposed-Modules: RungeKutta

All you need to do is find a nice category for it (with matching module name), change the cabal file accordingly, create an account at hackage (see http://hackage.haskell.org/packages/accounts.html) and upload it.

Hope this helps,

Martijn.

Damn, I never thought of that. Sorry! Guess I've only been haskell-hacking on my little old iMac... A new version is attached, with the version number bumped up by 0.0.1 and rungekutta.hs renamed to RungeKutta.hs. Hopefully it should work out-of-the-box now. Off to patch my repository...

It breaks on Linux (and all unices) because name of file in tarball is 'rungekutta.hs' not 'RungeKutta.hs' as required. In other words: god blame case-insensitive file systems.

After renaming everything works just fine. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

That sounds fine... I think I'll pick "Numeric. RungeKutta". I'll change it when I've cabalized & hackage-ized this puppy... Uwe On 4/20/09, Alexander Dunlap wrote:

It would also be nice if you could plug it into the hierarchical module system somewhere, perhaps renaming the module to "Data.Algorithm.RungeKutta" or "Numeric.RungeKutta" or "Math.RungeKutta". This is pretty much the standard practice now, I think.
