Running a program installed from cabal

  • 772

I want to run this program hosted on Cabal, the official repository of Haskell apps.

First I installed Cabal:

sudo apt-get install cabal-install
cabal update

Second I installed the program itself:

$ cabal install clanki

Installed safe-0.3.9

Building clanki-1.2.6...
Installed clanki-1.2.6

Third I tried to run the program:

$ clanki --list
clanki: command not found

Why is the program not found, despite using the recommended installation procedure?

    cabal installs to ~/.cabal, with the binaries going in ~/.cabal/bin. You have to add this path to your PATH:

    export PATH="$HOME/.cabal/bin:$PATH"

    The Haskell website says cabal can add symlinks to ~/bin (which gets automatically added to PATH):

    If you decided not to put this directory on your $PATH then you can get cabal to symlink binaries into another directory, eg ~/bin. To use this feature edit ~/.cabal/config and see the symlink-bindir field. Note that the ~/.cabal/config file is not created until you run a cabal command for the first time, eg cabal update.
