Fail to install on ArchLinux

[madjar]

Hello there. I'm trying to install stackage-cli on ArchLinux (cabal 1.22.2.0, ghc 7.10.1), and it fails to build.

Preprocessing executable 'stackage-sandbox' for stackage-cli-0.0.0...
[1 of 2] Compiling Paths_stackage_cli ( dist/build/autogen/Paths_stackage_cli.hs, dist/build/stackage-sandbox/stackage-sandbox-tmp/Paths_stackage_cli.o )
[2 of 2] Compiling Main             ( main/Sandbox.hs, dist/build/stackage-sandbox/stackage-sandbox-tmp/Main.o )

main/Sandbox.hs:321:46:
    No instance for (Foldable t0) arising from a use of ‘elem’
    The type variable ‘t0’ is ambiguous
    Note: there are several potential instances:
      instance Foldable (Const m) -- Defined in ‘Control.Applicative’
      instance Foldable (Either a) -- Defined in ‘Data.Foldable’
      instance Foldable Data.Functor.Identity.Identity
        -- Defined in ‘Data.Functor.Identity’
      ...plus 8 others
    In the first argument of ‘flip’, namely ‘elem’
    In the second argument of ‘(.)’, namely ‘flip elem "/\\"’
    In the first argument of ‘T.takeWhile’, namely
      ‘(not . flip elem "/\\")’

main/Sandbox.hs:321:51:
    No instance for (Data.String.IsString (t0 Char))
      arising from the literal ‘"/\\"’
    The type variable ‘t0’ is ambiguous
    Note: there is a potential instance available:
      instance Data.String.IsString [Char] -- Defined in ‘Data.String’
    In the second argument of ‘flip’, namely ‘"/\\"’
    In the second argument of ‘(.)’, namely ‘flip elem "/\\"’
    In the first argument of ‘T.takeWhile’, namely
      ‘(not . flip elem "/\\")’
cabal: Error: some packages failed to install:
stackage-cli-0.0.0 failed during the building phase. The exception was:
ExitFailure 1

This doesn't look like a problem with dependencies, so maybe ghc 7.10 isn't supported yet?

Thanks a lot!

Definitely looks like a GHC 7.10 issue, thanks for the report. Looking into it now.

[snoyberg]

This should now be resolved with 0.0.0.1 on Hackage, can you confirm?

[madjar]

I confirm that it works. Thanks a lot.

No problem, thanks for the report!
