I think they do work. cv-combinators depends on HOpenCV, which depends on
OpenCV 2.0.

I'm currently devoting most of my time to this and plan to continue doing

Cool. Thanks a lot for uploading this.
I have a question (and I confess that I haven't checked the link). How is
this related to or overlaps with cv-combinators?

I found [1] a few months ago. It outputs Java bytecode, so it should work
on android. Given that Android development in java is very well supported
in eclipse, you might want to use haskell/frege only for the internals of
your program and keep coding your interface in Java.

Hi,

AFAIK, haskell98 is only used to import System in Test.hs.
You should be able to remove the dependency on haskell98 from the
cabal file and install the library without problems. In order to test
it, move Test.hs to a temp directory after installing the library, add

Hi,
You code fails because a link is not a node of kind Text, I think.
What you want is to get the text from a child node of an anchor node.
