[Haskell-cafe] Open CV or alternate image processing library for Haskell on windows?

[Gregory Guthrie]

Thanks!
I’ll wait, and then try this later today.

And another previous note also described a successful install, I can also try that.

It seems to me that having easy install of such common libraries is a big advantage of C++/C#/.. even SML(!), and is important to wider usage of Haskell.

Hi,
Yes, I understand that - but if there is some install or usage dependency, or install procedure, I would hope to see it documented somewhere; perhaps I missed that?


The only installation procedure I can document is how to do this in linux. My guess is that it must be similar with windows.

1. Get the opencv library from opencv.willowgarage.com<http://opencv.willowgarage.com>
2. Install it and make a note where it installs
3. cabal install CV. If this fails with missing C libraries, then,
(4). cabal install CV --with-extra-lib-dirs=where_the_opencv_libs_are --with-extra-include-dirs=where_the_opencv_includes_are

However, wait few hours so I can push a new version to hackage. There are few things I've already discovered that fail to work with other people and I think I can fix them.

Disclaimer:
The CV package is something I threw together, originally in pre-cabal times. Back then I arguably wasn't a very good haskell-programmer and the whole thing was under an nda. Since then I've casually evolved the library to suit my needs. After I saw CV-combinators library released I made a petition to publish my codes in hopes that it would help other people doing similar things.

In short, although CV package is very very useful for me, it is not a perfect binding, and the implementation isn't really smart at places. I would like to make it great, however.
