7 minutes read

To install Haskell in Ubuntu, you can follow these steps:

  1. Open the terminal by pressing Ctrl+Alt+T.
  2. Update the package list by running the command: sudo apt update
  3. Install the Haskell compiler (GHC) and the Haskell build tool (Cabal): sudo apt install ghc cabal-install
  4. Verify the installation by checking the GHC version: ghc --version
  5. Update the Cabal package list: cabal update
  6. To make the changes take effect, run the command: source ~/.bashrc


By following these steps, you should have Haskell installed on your Ubuntu system. You can now start writing and compiling Haskell programs.

How do I configure an IDE for Haskell development on Ubuntu?

To configure an IDE for Haskell development on Ubuntu, you can follow these steps:

  1. Install Haskell: Open a terminal and run the command: sudo apt update && sudo apt install haskell-platform
  2. Install an IDE: The recommended IDE for Haskell development is "Haskell IDE Engine" (HIE). Open a terminal and run the following commands: sudo apt update sudo apt install ghc sudo apt install libicu-dev libtinfo-dev libgmp-dev zlib1g-dev libcurl4-openssl-dev libffi-dev libgmp-dev libgmp3-dev git clone https://github.com/haskell/haskell-ide-engine --recurse-submodules cd haskell-ide-engine stack ./install.hs hie
  3. Configure the IDE: Most text editors and IDEs will require additional configuration to work with HIE. For example, if you're using Visual Studio Code, install the "Haskell" extension by "haskell-ide-engine", and follow the prompts to configure the extension. If you're using other editors like Emacs, Sublime Text, or Atom, consult the respective documentation for configuring Haskell support with HIE.
  4. Install additional tools (optional): Some additional tools can enhance your Haskell development experience. Install "hlint" for code linting: sudo apt install hlint Install "stylish-haskell" for code formatting: sudo apt install stylish-haskell


With these steps, you should have a configured IDE for Haskell development on Ubuntu. Remember to consult the documentation of your chosen text editor or IDE for further customization options.


Are there any system requirements for installing Haskell on Ubuntu?

Yes, there are some system requirements for installing Haskell on Ubuntu. Here are the recommended requirements for installing Haskell:

  1. Operating System: Ubuntu 18.04 or later
  2. Disk Space: At least 5GB of free disk space
  3. RAM: At least 2GB of RAM, although 4GB or more is recommended
  4. Processor: Any modern x86 or x86_64 processor will work


These requirements should be sufficient for most Haskell development needs.


Are there any additional steps required to configure Haskell after installation on Ubuntu?

After installing Haskell on Ubuntu, there are a few additional steps you can take to configure it:

  1. Set up the Haskell build tool Stack (optional): Stack provides a consistent build environment for Haskell projects. You can install it by running the following command in your terminal: curl -sSL https://get.haskellstack.org/ | sh. Once installed, you can use it for building and managing Haskell projects.
  2. Configure GHC (Glasgow Haskell Compiler): GHC is the default Haskell compiler. You can create a configuration file named .ghci in your home directory to customize GHC behavior. In this file, you can set options or add additional import statements that you would like to have automatically loaded when running the GHCi interpreter.
  3. Install additional Haskell packages: By default, Haskell comes with a minimal set of packages. Depending on your needs, you may want to install additional packages. You can use the cabal command-line tool to install packages. For example, run cabal install package-name to install a specific package.
  4. Set up an Integrated Development Environment (IDE) (optional): You can use an IDE to write Haskell code. Popular choices include Visual Studio Code (with the Haskell extension), IntelliJ IDEA (with the Haskell plugin), and Emacs (with the haskell-mode package). Each IDE may have its own setup process, so refer to their respective documentation for instructions.


These are some common additional steps you can take to configure Haskell after installation on Ubuntu. Your specific requirements may vary, so refer to the documentation for Haskell and the tools you choose for more detailed instructions.
