Note that config file is missing from a new install!

Cabal Install

cabal-install is the command-line interface for Cabal.

It provides commands for installing cabal packages, including downloading packages from HackageDB and determining the dependencies among packages. It also provides commands for developers to configure, build, test and upload packages to HackageDB.

(Its predecessor, cabal-get, is now defunct.)

Usage

Usage: cabal [GLOBAL FLAGS]
   or: cabal COMMAND [FLAGS]

Global flags:
 -h --help            Show this help text
 -V --version         Print version information
    --numeric-version Print just the version number

Commands:
  install      Installs a list of packages.
  list         List available packages on the server (cached).
  update       Updates list of known packages
  fetch        Downloads packages for later installation or study.
  upload       Uploads source packages to Hackage
  configure    Prepare to build the package.
  build        Make this package ready for installation.
  copy         Copy the files into the install locations.
  haddock      Generate Haddock HTML documentation.
  clean        Clean up after a build.
  sdist        Generate a source distribution file (.tar.gz).
  hscolour     Generate HsColour colourised code, in HTML format.
  register     Register this package with the compiler.
  test         Run the test suite, if any (configure with UserHooks).

Typical step for installing Cabal packages:
  cabal install [PACKAGES]

Occasionally you need to update the list of available packages:
  cabal update

For more information about a command, try 'cabal COMMAND --help'.
This program is the command line interface to the Haskell Cabal Infrastructure.
See http://www.haskell.org/cabal/ for more information.

See the  cabal page for more complete usage information.

There is bash command line completion support available, though currently that requires installing manually.

Quick Installation on Unix

wget http://hackage.haskell.org/packages/archive/cabal-install/0.6.2/cabal-install-0.6.2.tar.gz
tar -zxf cabal-install-0.6.2.tar.gz 
cd cabal-install-0.6.2
./bootstrap.sh

You will now have the cabal binary in $HOME/.cabal/bin. You should also add this directory to your $PATH.

In cabal-install 0.6 and later you can symlink binaries into another directory, eg $HOME/bin which can be done instead of changing the $PATH. To use this feature edit ~/.cabal/config and see the symlink-bindir field.

Note: cabal-install 0.6 uses a new default ~/.cabal/config file which is somewhat self-documenting in that it lists all the valid (non-deprecated) fields along with their default values. If you previously used cabal-install 0.5.1 or earlier then you will not see the new format, so you may like to back up your existing config, let cabal-install 0.6 re-create the default config and then merge back any local changes. On Windows the configuration file is named $HOME/Application Data/cabal/config.

Reply to note: As of 19 April 2009, cabal-install does not actually create ~/.cabal/config. This omission causes major lossage---the cabal binary cannot find any packages. Reported as part of ticket number 541.

Ubuntu Intrepid Ipex 8.10

These packages must be installed to run successfully bootstrap.sh:

  • ghc6
  • libghc6-parsec-dev
  • libghc6-network-dev
  • libghc6-http-dev
  • libghc6-mtl-dev
  • zlib1g-dev

You can execute this command to satisfy these dependencies: 

sudo apt-get install ghc6 libghc6-parsec-dev libghc6-network-dev libghc6-http-dev libghc6-mtl-dev zlib1g-dev
