This page describes the installation of the Haskell toolchain, which consists of the following tools:
GHC: the Glasgow Haskell Compiler
cabal-install: the Cabal installation tool for managing Haskell software
stack: a cross-platform program for developing Haskell projects
haskell-language-server (optional): A language server for developers to integrate with their editor/IDE
Select your platform to get more specific installation instructions:
Alternative methods to install GHC are listed here.
Note: Apple Silicon is not yet supported. You will have to install GHC in arch -x86_64 compatibility mode using rosetta. See here and here for more pointers.
choco install haskell-dev, followed by refreshenv.Refer to your distribution package manager documentation. For convenience, below are a few distribution specific instructions, outlining 3rd party repository use as well.
Note: Most linux distros don’t allow different versions of GHC to be installed in parallel. Sometimes the GHC packages are a bit outdated as well. In either case, consider using GHCup instead.
Note: haskell-language-server isn’t packaged by most distributions. Instead you will have to install it manually, see the release page, unless you use VSCode, which bootstraps everything automatically. This is optional.
Steps to setup ghc and cabal are given in the ghc ppa
Packages from the PPA can be installed as follows:
sudo add-apt-repository -y ppa:hvr/ghc
sudo apt-get update
sudo apt-get install -y cabal-install-XXX ghc-YYYPackages are installed into /opt/ghc/bin and /opt/cabal/bin
Steps to setup stack are on the stack website.
Steps to setup ghc and cabal are given in the ghc debian apt repository
Steps to setup stack are on the stack website.
GHC, cabal-install and stack are in the official Fedora repos, to install:
sudo dnf install ghc cabal-install
There are also Fedora module streams with newer versions of ghc:
sudo dnf module list ghc
sudo dnf module install ghc:X.YThe different versions cannot be parallel installed.
There are also unofficial Fedora Copr repos with more recent cabal-install.
To install these older versions of ghc and cabal-install from the official EPEL repo, just run the install command:
sudo yum install ghc cabal-install
For newer versions of ghc you can use the unofficial Fedora Copr repos:
Note that the different ghc package versions cannot be installed in parallel.
Note: installing the Haskell toolchain via the Arch Linux package manager is not recommended, since it enforces dynamic linking, which can cause various issues. Instead consider GHCup.
The official repos on Arch Linux contain packages ghc, cabal-install, happy, alex, haddock. Install them with:
sudo pacman -S ghc cabal-install happy alex haskell-haddock-library
To install from official openSUSE:Leap repo, just run the install command:
sudo zypper in ghc cabal-install
For last stable version you can use the development openSUSE repository:
Use this command to add repository to your system:
sudo zypper ar -f -p 90 https://download.opensuse.org/repositories/devel:/languages:/haskell/openSUSE_Leap_15.1/devel:languages:haskell.repo
To install from official openSUSE:Tumbleweed repo, just run the install command:
sudo zypper in ghc cabal-install
While the Haskell toolchain is available in the main gentoo repository, it is recommended to use the more up-to-date gentoo-haskell overlay. This can be done using layman:
sudo layman -a haskell
sudo emerge --ask dev-lang/ghc dev-haskell/cabal-installGHC bindists are binary packages built as part of the GHC release process and are guaranteed to have passed the test suite. The installation process is a bit manual, so this is meant for power users.
The GHC download page gives an extensive overview of available options. Navigate to the version you seek and click on Binary packages. You may also visit downloads.haskell.org/~ghc for the complete list. Likewise, to install cabal-install manually visit downloads.haskell.org/~cabal.
Haskell-language-server binaries can be found here.
Building from source can be a difficult task, but may be necessary if all other installation options fail. Refer to the Haskell gitlab wiki for further instructions.
For building cabal-install from source, follow the instructions in the README.
For building haskell-language-server from source, follow the instructions here.
