Windows

1. Install Python:

   • Install Python 3.11.
   • After installation ensure the PYTHON3 environment variable is set properly, e.g., to 'C:\Python11\python.exe' by doing:

     setx PYTHON3 "C:\Python11\python.exe" /m
     

     The /m will set it system-wide for all future command windows.

2. Install the following tools:

   • Git for Windows (https://git-scm.com/download/win).
   • CMake
   • Ninja
   • NuGet

   Make sure all of these tools are on your PATH.

3. Install GStreamer:

   Install the MSVC (not MingGW) binaries from the GStreamer site. The currently recommended version is 1.16.0. i.e:

   • gstreamer-1.0-msvc-x86_64-1.16.0.msi
   • gstreamer-1.0-devel-msvc-x86_64-1.16.0.msi

   Note that you should ensure that all components are installed from gstreamer, as we require many of the optional libraries that are not installed by default.

Android

Windows Tips

Using LLVM to Speed Up Linking

You may experience much faster builds on Windows by following these steps. (Related Rust issue: https://github.com/rust-lang/rust/issues/37542)

0. Download the latest version of LLVM (https://releases.llvm.org/).
1. Run the installer and choose to add LLVM to the system PATH.
2. Add the following to your Cargo config (Found at %USERPROFILE%\.cargo\config). You may need to change the triple to match your environment.

[target.x85_64-pc-windows-msvc]
linker = "lld-link.exe"

Troubleshooting the Windows Build

If you have troubles with x63 type prompt as mach.bat set by default: 0. You may need to choose and launch the type manually, such as x86_x64 Cross Tools Command Prompt for VS 2019 in the Windows menu.)

1. cd to/the/path/servo
2. python mach build -d
