Some recent comments suggested that every time there is a new GHC release, there needs to be a new wxHaskell release (or insert name of other library here) to work with it. This seems to be true even for minor upgrades, like 6.4.1 -> 6.4.2.
These GUI libs tend only to break on major releases like 6.2 -> 6.4 and 6.4 -> 6.6. In both cases this was due to changes in the way packages are managed. Since these GUI libs are both pretty large and made of several packages they were affected. Many simpler projects were fine with the transition.
Why is this? Does GHC break binary compatibility at every release? Is this avoidable?
Yes this is what you're thinking about with minor upgrades like 6.4.1 -> 6.4.2, so any binary packages, eg windows installers need to be rebuilt from source to work with the new ghc version.
This makes using Haskell unnecessarily hard compared to other platforms.
Well, usually it's only a rebuild so as long as your build system is ok, it's not too hard. Duncan
