Issues with dependencies when trying to configure Setup.hs despite having dependencies installed

Question

I've been provided with a Setup.hs file, along with another .hs file that contains the source code. Whenever I try to configure the install by the following:

runhaskell Setup.hs configure

I get the error:

Setup: At least the following dependencies are missing: binary >=0.4.0 && <0.6.0, haskeline ==0.6.*

I've since installed these dependencies using cabal, but when I try to run the Setup configure command again, I get the same error. I'm completely new to Haskell - is there another step I'm missing after doing a cabal install before trying to run Setup again?

What is the output of runhaskell --version? – Passible

Answer 1

How did you install the packages? If you installed them with the --userflag, then you also need to configure with the --user flag.

You can verify that the packages are installed by running ghc-pkg list binary and ghc-pkg list haskeline. It will list the installed package versions matching that name along with where they are installed.

I installed the packages through cabal. I've verified that they are installed. Here's the output from that: "mawhidby$ ghc-pkg list binary /Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/package.conf.d /Users/mawhidby/.ghc/i386-darwin-6.12.3/package.conf.d binary-0.5.0.2 mawhidby$ ghc-pkg list haskeline /Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/package.conf.d /Users/mawhidby/.ghc/i386-darwin-6.12.3/package.conf.d haskeline-0.6.3.2" – Krystalkrystalle

@mawhidby: The packages are installed in your user database(/Users/mawhidby/...), but Cabal only searches the global database by default. You need to add the --user flag when you configure. – Koziarz
