# Installation Guide

1. Get the code

git clone https://github.com/WebAssembly/wabt

Downloads the entire project code from GitHub to your computer.

cd wabt

Moves into the project folder you just downloaded.

2. Official Install Script

Easy Recommended

Prerequisites

Homebrew A package manager for macOS/Linux.
APT (Debian/Ubuntu 계열) Built into Debian/Ubuntu-based Linux distributions.

brew install wabt

Installs the pre-built package via Homebrew — no source build required.

sudo apt install wabt

Installs directly from the APT package repository (Debian/Ubuntu-based).

✅ After installing, open a new terminal and run the program's version command (e.g. --version) to confirm it worked.

Pulled directly from this repo's README.

3. CMake

Medium

Prerequisites

Git Needed to download the project code from GitHub.
CMake The tool used to generate build configuration.
C/C++ 컴파일러 Windows needs Visual Studio (Community edition, free), macOS needs Xcode Command Line Tools, Linux needs the gcc/g++ package.

$ cmake ..
