How to Install Haskell on Windows in 2025

Are you ready to start your journey with Haskell, the functional programming language renowned for its lazy evaluation and statically-typed syntax? Installing Haskell on Windows is your first step. In this guide, we’ll walk you through a simple, step-by-step process to get Haskell up and running on your Windows machine in 2025.

Why Install Haskell?

Before diving into the installation process, it’s worth mentioning the benefits of using Haskell: - Strong static typing: Reduces runtime errors. - Immutability: Promotes safer and more predictable code. - Lazy evaluation: Allows efficient handling of infinite data structures.

Step-by-Step Guide to Install Haskell on Windows

Step 1: Download the Haskell Platform

The easiest way to install Haskell on Windows is through the Haskell Platform. In 2025, the platform has made significant advances in streamlining installations for Windows users.

  1. Visit the Haskell Platform Website: Go to the official Haskell Platform and download the latest version available for Windows.

  2. Select the Installer: Choose the appropriate installer for your system architecture (32-bit or 64-bit).

Step 2: Run the Installer

  1. Locate the Installer: Once downloaded, locate the installer in your downloads folder.

  2. Launch the Installer: Double-click the installer file to start the installation process.

  3. Follow the Setup Wizard: Proceed through the setup wizard, following the on-screen instructions. Opt for the default selections unless you have specific requirements.

Step 3: Verify the Installation

To ensure Haskell is installed correctly:

  1. Open Command Prompt: Type cmd in your Windows search bar and hit Enter.

  2. Check GHC Version: Type ghc --version in the command prompt. You should see the version information if Haskell is installed successfully.

Step 4: Test a Simple Haskell Program

  1. Write a Simple Program: Open a text editor and write a simple “Hello, World!” program in Haskell.
   main :: IO ()
   main = putStrLn "Hello, World!"

  1. Save Your Program: Save the file with a .hs extension, for example, HelloWorld.hs.

  2. Compile with GHC: Navigate to the directory containing your file in the command prompt, and compile it:

   ghc HelloWorld.hs
  1. Run Your Program: If the compilation is successful, run the executable generated:
   HelloWorld
