[Haskell-cafe] no end to the build errors! (wxhaskell, afrp)

[Yang]

argh, still more build errors on various fronts. i'm using ghc-6.6 on
fedora core 5 unless otherwise noted. thanks in advance for help on
any of these.

a lot of this is part of my attempt to learn more about and play with
a high-level functional gui library (and, of course, for getting a
better grasp on what frp and arrows are all about) after realizing
that i would never ever be able to get fruit working. i have so far
found wxfruit (built on wxhaskell) and FG (built on gtk). i am
interested in implementing a similarly 'highly-declarative' ui library
built on hscurses.widgets.

Ditch it; it hates ghc 6.6. darcs get http://darcs.haskell.org/
wxhaskell

I can't help with the others.

thanks for the timely response.

using this wxhaskell and the (just-in-time re-released) yampa (it
built/installed fine, unlike the old afrp release i tried earlier), i
tried again to build wxfruit:

$ ghc --make WXFruit.hs

WXFruit.hs:12:17:
Could not find module `Graphics.UI.WX':

looking into this, it appears that either wxhaskell has recently
(judging from the docs on the official wxhaskell site) undergone a big
reorg, or i'm still missing some wxhaskell libs. does this mean that i
won't be able to get wxfruit working (without hacking it to update its
usage of wxhaskell)?

thanks, now wxhaskell is installed. (i recommend adding this detail to
the docs - i didn't see the message at the end of the make job at all
because of the tools i use to automate this process.)

now the error i get from wxfruit is:

$ ghc --make WXFruit.hs
[1 of 1] Compiling WXFruit ( WXFruit.hs, WXFruit.o )

WXFruit.hs:81:31: parse error on input `->'
