Re: [Haskell-beginners] Question about ghc and cabal: finding packages

Thanks guys for the helpful comments! I will try the "cabal configure" way tonight. Cheers! Christian 2010/8/19 Daniel Fischer

Try simply

cabal configure

in the directory where Setup.lhs (and your .cabal file) is located.

/J

Or, to configure, build and install in one go, just `cabal install' in that directory. If you want to go the runhaskell Setup.[l]hs road, however, you have to pass the --user flag to runhaskell Setup.[l]hs configure if you need packages from your user db. Or you have to reinstall the cabal-installed packages globally (surprise: pass the --global flag to cabal install), perhaps set `user-install: False' in ~/.cabal/config if you want to have global installs by default.

Hi everyone, I have installed ghc 6.12.3 and the Haskell platform; now, when I install packages from hackage using cabal install <package-name>, they get installed in ~/.cabal, which is fair enough. However, when I call a runhaskell Setup.lhs configure that used to work on a different computer with the same software setup, ghc (or is it cabal?) complains that it cannot find the packages I have just installed. Checking again revealed that they are indeed installed, just not in the ghc installation directory, but under ~/.cabal. How can I tell cabal and/or ghc where to look for libraries?

Thanks, again, for any help! Christian
