com.unity.sdk.linux-x86_64

This package provides the required 64-bit(x86_64) sysroot for building IL2CPP-based Unity players targeting both Linux and Embedded Linux platforms. It contains the system headers and libraries needed to compile and run Unity players, and is intended to be used in conjunction with a matching Unity-provided toolchain package on the host platform.

For an overview of Unity Embedded Linux support, see Getting started with Embedded Linux.

Choosing the correct toolchain package

When building IL2CPP-based Unity players targeting 64-bit(x86_64) Linux or Embedded Linux, you must pair this sysroot package with the appropriate Unity toolchain package based on your host development platform.

Host Platform	Recommended Toolchain Package
Linux x86_64	com.unity.toolchain.linux-x86_64-linux
macOS x86_64	com.unity.toolchain.macos-x86_64-linux
macOS ARM64	com.unity.toolchain.macos-arm64-linux
Windows x86_64	com.unity.toolchain.win-x86_64-linux

Building IL2CPP Players for Linux and Embedded Linux

After the appropriate toolchain package has been installed for the host platform, open the Unity project and navigate to:

Project Settings > Player > Configuration, then set the Scripting Backend to IL2CPP.

To build the player:

1. Open File > Build Settings.
2. In the Target Platform dropdown, select either Linux or Embedded Linux.
3. If Embedded Linux is selected, choose x64 as the desired Architecture.
4. Click Build or Build and Run to generate the player executable.
