Building Unity 2022 Projects for Quest 2: ECS 1.0 and IL2CPP Issues Explained

Developing for Oculus Quest 2 can be an exciting journey, especially with the latest advancements in Unity. However, many developers encounter challenges, particularly when trying to implement Entity Component System (ECS) 1.0 in Unity 2022 using the IL2CPP scripting backend. If you're experiencing repeated crashes during your builds to Quest 2, you're not alone.

In this guide, we will explore the root cause of this issue and provide possible solutions, so you can continue your development with minimal interruptions.

The Problem: Crashes with Unity 2022, ECS 1.0, and IL2CPP

A Unity developer faced a situation where their project built correctly for the Rift S and in the editor, but it resulted in crashes when attempting to build for the Oculus Quest 2 using IL2CPP. Strikingly, when the developer switched to the Mono backend, the build functioned correctly, which raised a critical question:

Is it feasible to build a Unity 2022 project that uses ECS 1.0 on the Quest 2 with the IL2CPP scripting backend?

Understanding the Crashes: An Overview

Crash Reports: The developer provided a crash report that showed various errors with IL2CPP, indicating potential issues in memory access or incompatible commands during runtime.

Specific Errors:

Signal 11 (SIGSEGV): This error often indicates an attempt to access an invalid memory address, which might lead to program crashes.

Various codes and backtrace information were logged, exposing the underlying faults occurring in 'libil2cpp.so', an important component of the IL2CPP backend.

The Solution: Workarounds and Potential Fixes

Immediate Workarounds

While a solution specific to Unity 2022 may not be available at the moment, here are some practical alternatives to consider:

Use of Older Versions:

If you want to successfully build for the Quest 2 using IL2CPP and ECS, the current workaround is to use Unity 2021.3.8f1 with DOTS 0.51.1. This combination is reported to work without crashes.

Stay Updated:

Developers should keep an eye on updates from Unity. Early feedback suggests that the issue with IL2CPP causing crashes in builds might have been identified, and fixes could be rolled out soon. Reportedly, Unity 2022.0.0b11 could potentially resolve these issues, so it’s advisable to test your project with this version once it’s available.

Future Considerations

Community Support: Engage with the Unity developer community. Forums and support channels can provide real-time solutions and insights based on collective experiences.

Unity Documentation: Regularly consult Unity's update notes. They often provide important information on bug fixes, new features, and known issues that could impact your projects.

Conclusion

Building projects for the Oculus Quest 2 using Unity can sometimes present challenges due to compatibility issues between different technologies like ECS and IL2CPP. For now, using Unity 2021.3.8f1 with DOTS 0.51.1 remains your best option for a stable build. As Unity updates and recognizes these issues in newer versions, developers can hope for a seamless experience with ECS 1.0 in the near future.

Stay empowered in your development, carry out thorough research, and adapt as needed. Happy developing!
