Hi there,

I have a problem installing erd on my system.

Using cabal install erd, I get

cabal: Could not resolve dependencies:
trying: erd-0.1.3.0 (user goal)
next goal: base (dependency of erd-0.1.3.0)
rejecting: base-4.8.0.0/installed-901... (conflict: erd => base==4.7.*)
rejecting: base-4.8.0.0, 4.7.0.2, 4.7.0.1, 4.7.0.0, 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)
Dependency tree exhaustively searched.

Trying to download the source and firing up cabal configure, graphiz does not seem to be found.

Configuring erd-0.1.3.0...
cabal: At least the following dependencies are missing:
graphviz ==2999.*

cabal update was previously run.

Any held would be appreciated.

@abertschi I feel like this commit might fix your issue. Perhaps you can try to install erd from latest source?

@BurntSushi What do you think? Would it help to update the version published on cabal?

eric-brechemier commented 9 years ago

@abertschi I tried a fresh install from OS X 10.10.3 today, and I had no issues:

I followed these steps:

  1. Install GHC for OSX from: https://www.haskell.org/downloads/osx
  2. launch GHC for OSX and follow step by step instructions to configure ghc
  3. from a terminal, run cabal update to initialize the list of packages for cabal
  4. install erd by running cabal erd

EDIT:

  1. I installed graphviz at a later step, using homebrew: brew install graphviz

@eric-brechemier, I cloned your fork from this commit, performed a cabal updateand cabal install erd with brew install graphviz beforehand and managed to solve the issue. Thanks a lot.

@abertschi I'm glad it helped. For your information, this commit has been merged upstream, so you should be good to go with the master branch of the main project (BurntSushi/erd) as well.
