How to Compile Servo From Source Code - Servo

To compile Servo from source code, clone the repository from the official source, install Rust and required dependencies, then run the build command in your terminal.

Servo is a free, open-source web engine built in Rust. Compiling from source allows developers and web technology enthusiasts to customize the build, contribute to development, or test experimental features. The process requires a development environment configured with specific prerequisites.

Prerequisites for Building Servo

Before you compile Servo from source code, ensure your system meets the requirements. Install Rust, which powers Servo's entire codebase. Download Python 3.8 or later, as build scripts depend on it. You'll need Git to clone the repository.

Linux users should install build-essential, pkg-config, and development headers. macOS requires Xcode Command Line Tools. Windows users need Visual Studio Build Tools. These prerequisites vary slightly by platform but are essential for successful compilation.

Compiling Servo from Source Code

Navigate to your desired directory and clone the Servo repository using Git. After cloning completes, enter the directory. Run `./mach build --release` to compile Servo from source code with optimization flags enabled. The build process takes 15–60 minutes depending on your hardware.

On Linux and macOS systems, you may use `./mach build --dev` for faster development builds without full optimization.

Post-Build Steps

After successful compilation, the compiled binary appears in the target directory. Test the build by running `./mach run` to launch the compiled web engine. This confirms your compile process succeeded. Documentation and additional options are available through `./mach help`.

Compiling Servo from source code suits developers who need customization, want to contribute patches, or require platform-specific builds unavailable in precompiled releases. Review the official documentation for platform-specific instructions before starting.
