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

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.
