Building fails with ghc-6.12.3 on Ubuntu 11.04 about reactive-banana HOT 4 CLOSED

Hello Daniel,

there are two things happening:

• reactive-banana actually depends on version >= 4.3.0.0 of the base libraries due to the use of the void function. I didn't specify that carefully.
• GHC 6.12 is stuck with version 0.3 of the containers library, which means that reactive-banana is not compatible.

I would recommend installing GHC 7. If that's unfeasible, I can try to make it compatible with older GHC versions.

Thanks, upgrading the 'ghc' Ubuntu package to 7.x did the trick for me with reactive-banana[-wx]. Now the only thing that still won't compile is the BlackBoard demo app. After some hacking on the cabal dependencies and changing module names around, I'm left with this:

% cabal configure && cabal build
Resolving dependencies...
Configuring Blackboard-0.1...
Preprocessing executables for Blackboard-0.1...

[5 of 9] Compiling Reactive.GraphicOpt ( src/Reactive/GraphicOpt.hs, dist/build/Blackboard/Blackboard-tmp/Reactive/GraphicOpt.o )

src/Reactive/GraphicOpt.hs:72:10: Not in scope: `merge'

Please take a look at my naïve fixing attempts at https://github.com/danwerner/reactive-banana. Perhaps I made some incorrect assumptions about how the module names have changed?

Ah, the BlackBoard application suffers from bitrot already, it still requires reactive-banana 0.1. Updating takes more work.

You may want to have a look at the examples in reactive-banana-wx instead.

I see, thanks for pointing that out. I will take a look at the newer examples instead.
