elm-server: Seg fault

[marklar]

Same problem (i.e. Seg fault) for elm-repl, elm-doc, and elm-get.

Do you have bash or some alternative command line interface?

Also, if you get literally that error both times, it appears that the results of the Mac installer are shadowing the results of cabal. If you remove all of the Elm stuff from /usr/local/bin and /usr/local/share/elm (iirc) then you'll be dealing only with the results of cabal.

[marklar]

Thanks for your prompt reply!

I use bash.

It now works. Here's what I did:

• Removed all the Elm stuff from /usr/local/bin and /usr/local/share/elm.

• Since the cabal stuff appears to be in ~/Library/Haskell/ghc-7.6.3/lib, I added the following to my .bashrc:

  export PATH=$PATH:~/Library/Haskell/ghc-7.6.3/lib/Elm-0.12.1.3/bin
export PATH=$PATH:~/Library/Haskell/ghc-7.6.3/lib/elm-server-0.11/bin
export PATH=$PATH:~/Library/Haskell/ghc-7.6.3/lib/elm-get-0.1.1.3/bin
export PATH=$PATH:~/Library/Haskell/ghc-7.6.3/lib/elm-repl-0.2.2.1/bin

I suspect there is a much more elegant/concise solution.

[evancz]

I believe Haskell places symlinks to all executables in ~/Library/Haskell/bin, so you can just add that to your path instead of all the individual ones. Does that work?

[marklar]

Yes! Terrific, thanks!

[evancz]

Cool :) The initial problem is still pretty weird. Can you say more about your system? Is there anything odd that it'd be good to know about?

[marklar]

Yes, the initial problem is strange. ...It's difficult for me to guess what, if anything, about my system might be the cause.

I'll attempt to re-install using the Mac installer to see whether the problem re-manifests.

[marklar]

I'm sorry to say that the problem with the Mac installer persists for me:

$ elm-server
/usr/local/bin/elm-server: line 6: 33305 Segmentation fault: 11  /usr/local/bin/elm-server-unwrapped $*

Oh, now that I look with fresh eyes, this reminds me of an issue I have seen before. I created the binaries on OSX 10.10 and I recall hearing of issues running binaries on 10.7 or something like that.

The two solutions are (1) I need to compile on an older machine (which I don't have easy access to) or (2) you can try to go through the "platform agnostic" install.

[evancz]

Alright, elm-sever no longer exists, so I'm gonna close this one!
