-- Configuring incomplete, errors occurred!

It looks like some dependency packages were missing during the build, so I’ve added them in Dockerfile.multiarch.base.

As for the failed workflow, I can't reproduction it locally, that job in my repo has passed: links

Let me try to force push again to restart the workflow.

As described in our CONTRIBUTING.md, please address issues with additional commits. The force-pushes require us to re-review the full PR instead of just looking at the changes. (Nothing to be done at this point right now, but for the future.)

Alright, I’ve double-checked: my repo’s CI passes all tests now, but the pr’s CI is failing... :(

The only CI that should fail by this change is "Linux artifacts", which you can't run on our own.

It is currently failing, but for a very different reason (PROGRESS!! ??):

Looks like it is a protobuf or absl bug, but caused by riscv being a snowflake? protocolbuffers/protobuf#14549 and abseil/abseil-cpp#1561 The "fix" looks like a workaround. Unfortunately, that means just upgrading a component isn't likely to fix this.

There is a possibility this is caused by a particular version of GCC or the like. If you don't see this on your machine, then maybe Ubuntu 18.04 (multiarch image) has the trouble but Ubuntu 20.04 or 22.04 won't?

Both Ubuntu 18.04 and 20.04 are out of their regular support window. I'll need to cross-check with the glibc version on Debian, but I might just upgrade those images and see if this problem fixes itself.

Interesting....

It passed and what I do was just back to the HEAD^

The Linux Artifacts CI hadn't run yet. I have to start it for you. I've started it.

So sorry about that, I found a bug in my code.

The reason was that I used a patch-file to load my changes, but my changes are based on 1.5x.x. When I patched it in 1.7x.x, it went wrong because line-number location. So sorry about that.
