Re: [reactive] reactive 0.10.5 Install problem

18 Feb 2009

...
...
I was running ghc 6.8.3 and upgraded to 6.10.1 as it seemed
that it would be more 'reactive' friendly.
Platform is  x86_64 GNU/Linux.
All seemed to go smoothly but I can't install reactive 0.10.5.
Error message  ............
[poliquin@curunir reactive-0.10.5]$ runghc Setup configure --user
Configuring reactive-0.10.5...
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.
package reactive-0.10.5 requires QuickCheck-1.2.0.0
package checkers-0.1.3 requires QuickCheck-1.2.0.0
package Stream-0.3.1 requires QuickCheck-2.1.0.1
...
I just had the same problem. The very latest version of Stream changed
its dependencies in a minor version. Try this:
su
ghc-pkg unregister Stream --force
cabal install Stream-0.3 Reactive
Thanks!
This allowed me to install reactive !
(I'll try it out tomorrow)

The unregister broke my arrows-0.4.1,
when I reinstalled it complained that Stream
wasn't installed with profiling .. So,

ghc-pkg unregister Stream --force
cabal install -p Stream-0.3
cabal install -p arrows-0.4.1

And all is well!

Thanks very much for the help,

Tom

I hope this is the correct place to ask this.
I've been playing with Haskell for a few months (I'm a long time
imperative programmer with a couple years of Scheme)
and *still* feel like a complete newbie. It seems like there's
always something new to wrap my head around (one
could argue this makes it fun .. ?). Java never twisted
my brain :-)
I eventually want to write a simulator for an alternate computer
architecture in Haskell. . I played around with arrows and managed to
understand the Arrow SF versions fibonacci and factorial and get them
running.
It appears reactive may be more appropriate.
