scion-lib - issue #54

Dependency Hell


Posted on Jan 31, 2014 by Helpful Wombat

* What steps will reproduce the problem? 1. Cabal version 1.16.02 2. GHCI 7.6.3 3. Run cabal install in the git project directory

* What is the expected output? What do you see instead? Expected to have a successful install of the scion server. Instead get dependency issues. I tried hacking the scion.cabal file by changing the version numbers but it's one dependency issue after another.

Resolving dependencies... cabal: Could not resolve dependencies: trying: scion-0.3 rejecting: base-4.6.0.1/installed-6c3... (conflict: scion => base>=4.2 && <4.6) rejecting: base-4.6.0.1, 4.6.0.0, 4.5.1.0, 4.5.0.0, 4.4.1.0, 4.4.0.0, 4.3.1.0, 4.3.0.0, 4.2.0.2, 4.2.0.1, 4.2.0.0, 4.1.0.0, 4.0.0.0, 3.0.3.2, 3.0.3.1 (global constraint requires installed instance)

* What version of the product are you using? On what operating system? Mac os x maverick.

* Please provide any additional information below. Could you update your scion.cabal file please so the build is succesful with the above version of ghci and cabal. Thanks.

I would say it's not actually a matter of just these versions, but a lot of the dependencies are pretty old. The Git hasn't been updated in a year.

I got past the dependency issue, however I still wasn't able to get this to compile, so there likely really is issues that are beyond just updating the scion.cabal file.

I have the same problem. Scion is uninstallable, and so Emacs Haskell mode is completely useless. Please fix this.
