Re: [Haskell-cafe] cabal-install sandbox with happy and alex

Hi Brandon, thanks for the suggestion. Unfortunately, it didn't do the trick: [0 :)] badi@olorin /private/tmp/sb ~> export PATH=/tmp/sb/.cabal-sandbox/bin:$PATH [0 :)] badi@olorin /tmp/sb ~> cabal install happy alex Resolving dependencies...

I've run into difficulty building happy and alex using the sandbox feature of cabal-install 1.18.0.2. Installation of dependencies succeeds but both happy and alex fail with:

setup: The program happy is required but it could not be found

My workaround is to use the --only-dependencies flag, install the dependencies, and manually install the packages.

I've run into this problem myself on Linux. My solution is to install ghc, happy, alex, hlint and cabal-install from debian packages and everything else using cabal install (either with or without using sandboxes).

At a guess, both of you need to find the bin directory created *in the sandbox* and add it to $PATH while working in the sandbox. Perhaps there is some better way for cabal sandboxes to handle this automatically.
