I have the latest cabal-install

[jvoigtlaender]

What exactly have you done before the cabal install --only-dependencies call? Please show the full shell session. Have you done what the README tells you to do?

First get the Elm developer workflow setup by reading the build from source instructions, then running this script with runhaskell BuildFromSource.hs master.

[jvoigtlaender]

@aestheticsdata, can this be closed, or are you still having problems building the site locally?

[HParker]

@jvoigtlaender I seem to be having a related issue.

@HParker, you are doing runhaskell BuildFromSource.hs master, on which https://github.com/elm-lang/elm-platform#actually-build-elm-things rightfully says:

Be aware, this is where active development happens, so not everything will be working at all times!

That is exactly what is happening to you: Right now the master branches of the different repositories are not in a state such that they can all be built together. There is no remedy. Use runhaskell BuildFromSource.hs 0.16 or wait until the master branches are in synch again.

[HParker]

Sounds good! thanks @jvoigtlaender

[jvoigtlaender]

Just to clarify: If all you are trying to do is play with the Elm website source, doing runhaskell BuildFromSource.hs 0.16 should be perfectly fine for you. You don't need anything in master on top of 0.16 for elm-compiler etc. Of course, you can still use master from the website repository here.

[HParker]

I was hoping to contribute back as well. Will I need to wait for master to be in synch again first? Is there anything I can do to help with this?

[jvoigtlaender]

Contributing to the https://github.com/elm-lang/elm-lang.org repository does not require you to use anything newer than 0.16 of https://github.com/elm-lang/elm-compiler etc.

[HParker]

Got it. Thanks again.

@xarvh, I guess you shouldn't be surprised that you get the same problem as the OP if you make the same mistake as the OP. The mistake is: ignoring what the README of this repository says.

It says:

First get the Elm developer workflow setup ...

Then in the Elm-Platform/master/ directory, run these commands:

Your log doesn't look like you have done that. Have you?

Additional notice, also present in the above discussion already: For now, you should replace master by 0.16 in runhaskell BuildFromSource.hs master and Elm-Platform/master/.

[xarvh]

Oww, sorry. =( Will follow through as soon as I have the time to upgrade ghc.

[jvoigtlaender]

@aestheticsdata, please close.

[evancz]

Cannot debug here. Get help in some other forum.
