This Cabal Git repository contains the following packages:

• Cabal: the Cabal library package (license)

The canonical upstream repository is located at https://github.com/haskell/cabal.

Prebuilt binary releases can be obtained from https://www.haskell.org/cabal/download.html. The cabal-install binary download for your platform should contain the cabal executable.

Assuming that you have a pre-existing, older version of cabal-install, run:

cabal install cabal-install

To get the latest version of cabal-install. (You may want to cabal update first.)

To install the latest version from the Git repository, clone the Git repository and then run:

(cd Cabal; cabal install)
(cd cabal-install; cabal install)

Assuming you don't have a pre-existing copy of cabal-install, run:

cabal-install $ ./bootstrap.sh # running ./bootstrap.sh from within in cabal-install folder.
