Cabal

This Cabal Git repository contains the following main packages:

Cabal: the Cabal library package (license)
Cabal-hooks: the library providing an API for the Cabal Hooks build type (license)
Cabal-syntax: the .cabal file format library (license)
cabal-install: the package containing the cabal tool (license)
cabal-install-solver: the package containing the solver component of the cabal tool (license)

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

Ways to get the `cabal-install` binary

GHCup (preferred): get GHCup using the directions on its website and run:
```
ghcup install --set cabal latest
```
Download from official website: the cabal-install binary download for your platform should contain the cabal executable.

Preview Releases

Getting unreleased versions of cabal-install: gives you a chance to try out yet-unreleased features. Currently, we only provide binaries for x86_64 platforms.

GitHub preview release built from the tip of the master branch: download from GitHub or use this GHCup command to install:
```
ghcup install cabal -u https://github.com/haskell/cabal/releases/download/cabal-head/cabal-head-Linux-x86_64.tar.gz head
```
Replace "Linux" with "Windows" or "macOS" as appropriate.

The default Linux build is dynamically linked against zlib, gmp and glibc. You will need to have appropriate versions of these libraries installed to use it. Alternatively a statically linked "Linux-static" binary is also provided.

You might need to add the following to your cabal.project file if your build fails because of an out-of-date Cabal library:
```
allow-newer:
  *:Cabal,
  *:Cabal-syntax

source-repository-package
    type: git
    location: https://github.com/haskell/cabal.git
    subdir: Cabal Cabal-syntax
```
Even more cutting-edge binaries built from pull requests are always available from the Validate worklow page on GitHub, at the very bottom of the page, or from the build-alpine workflow for statically linked Linux builds.

Ways to build `cabal-install` for everyday use

With cabal-install: if you have a pre-existing version of cabal-install, run:
```
cabal install cabal-install
```
to get the latest version of cabal-install. (You may want to cabal update first.)
From Git: again with a pre-existing version of cabal-install, you can install the latest version from the Git repository. Clone the Git repository, move to its root, and run:
```
cabal install --project-file=cabal.release.project cabal-install
```
Bootstrapping: if you don't have a pre-existing version of cabal-install, look into the bootstrap directory.
