Hello! Thank you for your detailed description of the issue.
The error you’re facing with the Torizon containerized Yocto build is known and was discussed in the community post you referenced. It relates to how newer toolchains treat some code as errors, which causes failures in recipes like elfutils.
Choosing the Correct Torizon/Crops Version
- There isn’t an official Ubuntu-based
torizon/cropscontainer; the provided containers are based on Debian for both the Kirkstone (6.x.y) and Scarthgap (7.x.y) versions. - The recommended practice is to use the latest supported Torizon container for your Torizon OS version—e.g., for Torizon OS 7.x.y, use
torizon/crops:scarthgap-7.x.y. However, for 6.x.y (Kirkstone), you may face issues as some host/container combinations receive fewer updates as support focus moves to recent releases.
Workarounds
1. Upgrade to Torizon OS 7.x.y (Recommended if Possible)
If you are able, consider upgrading to Torizon OS 7.x.y and use its corresponding container torizon/crops:scarthgap-7.x.y. The build scripts have improved compatibility and maintenance for newer distributions:
2. Use a Native Build on Ubuntu
Since you are using Ubuntu 22.04 (an officially supported distribution for Yocto builds), you could set up a native build environment instead of a container. This avoids the host/container compatibility issues:
3. Patch the Problematic Recipe
The elfutils build failure might be fixable by locally patching the recipe to relax -Werror usage or adjust flag handling. This is more advanced and may be necessary for Kirkstone builds if you must stick with an older release. Refer to this workaround for more information.
4. Custom CROPS Container (Advanced)
If you require a custom build environment (e.g., based on Ubuntu), you could create your own Docker image using the Dockerfile from the crops repository as a base, adapting it for Ubuntu. However, this approach would require careful dependency handling and is only recommended for advanced users.
Summary Table
| Approach | Links | Recommended When |
|---|---|---|
| Use Torizon OS 7.x.y | Build instructions for 7.x.y | New designs/upgrades |
| Native build on Ubuntu | Yocto build natively | Host is Ubuntu/Debian |
| Patch troublesome recipe | Community workaround | Must stay with 6.x.y |
| Custom CROPS container | CROPS Dockerfile repo | Custom expertise needed |
If possible, moving to a native build on your Ubuntu host or updating to Torizon OS 7.x.y will provide the most stability and compatibility with current container images and dependencies.
