haskell platform support

[pitermarx]

I couldn't compile with the haskell platform installed. (base =4.7)
What can i do? is it possible to support it?

What error do you see? This commit (e39edbc) should have resolved any issues.

Having the same problem

[egonSchiele]

Do you guys use cabal sandboxes?

[kepeterson]

Yeah, I tried it both with and without a sandbox.

I asked a Stack Overflow question which clarified things a little for me but I still don't really know how to fix it.

[egonSchiele]

I just pushed a fix, could you please try again?

[kepeterson]

In a fresh cabal sandbox:

$ cabal install --dependencies-only
Resolving dependencies...
cabal: Could not resolve dependencies:
trying: Cabal-1.20.0.2/installed-b86... (user goal)
trying: Chips-0.1.0.0 (user goal)

Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.

Looks like a different error at least.

Unfortunately there's no way for me to know what versions of the libraries are on your machine, so this will be a bit of guess-and-check. Try changing the build-depends section in Chips.cabal to this:

build-depends:       base >=4.6,
                     gloss ==1.8.*,
                     lens ==3.9.*,
                     mtl ==2.*,
                     template-haskell ==2.*,
                     ActionKid ==0.1.*,
                     time,
                     aeson ==0.6.*,
                     bytestring ==0.10.*

[kepeterson]

With that new build-depends I get Failed to install array-0.4.0.1.

I don't think I can help with this, sorry :/ Looks like you have stumbled into cabal hell. This is something specific to your machine, so you will have to figure out how to resolve it. There are a lot of resources online that should help.
