[Haskell-cafe] Installing agda through cabal
Hi all, I am trying to install agda through cabal but I get this: $ cabal install alex Resolving dependencies...

This would require modifying the path (since there may be no writable location on the existing path). But the PATH is set by a combination of several programs written in Turing-complete languages (shell script), and those programs themselves are in unknown locations (depending on the shell in use). or at least, they are in the PATH of the apps built by cabal itself? This is a possibility. But surely you're one day going to want to run your cabal-installed programs yourself (there are some pretty handy ones), so the easiest thing is to extend your path. It might be a good idea for cabal-install to warn that its bin directory is not in your path when you install an executable. --Max ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

You're right. Added .cabal/bin to path and everything is ok. It might be a good idea for cabal-install to warn that its bin directory is not in your path when you install an executable. Yep, might be an interesting idea for warning. :) --Max ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Yep, might be an interesting idea for warning. :) This has been discussed in connection to the question where cabal should by default install things. IIRC, the plan is to have cabal display a message on first startup asking the user for the default install location [of binaries] and telling them to make sure it's in the path. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
