I added the macOS 13 (x86_64) runner in this PR: https://github.com/stevenlovegrove/Pangolin/pull/903. This passes. Unfortunately, the arm64 runners for macOS are not for free. Can you reproduce this when compiling for the x86_64 architecture as on the CI?

JetForMe commented 9 months ago

Oh gosh I don't have an x86 machine readily available to try.

christian-rauch commented 8 months ago

Can you run a compiler or VM through Apple's Intel->ARM translation? Or compile via cross-compilation?

JetForMe commented 8 months ago

I don't think so, certainly not without a lot more effort than I have time to dedicate right now. How much money would the arm64 runners cost? Perhaps I can sponsor that work with cash?

christian-rauch commented 8 months ago

How much money would the arm64 runners cost? Perhaps I can sponsor that work with cash?

In the "M1 macOS larger runner" announcement (https://github.blog/2023-10-02-introducing-the-new-apple-silicon-powered-m1-macos-larger-runner-for-github-actions/) they say this will be $0.12 to $0.16 per minute. The two pipelines that currently run take approx. 6 minutes each. That would be at least $1.44 per pipeline run. That's quite a lot just for testing on a different CPU architecture. Also, I don't know who would need to manage the subscription.

I assume that those arm64 runners will be available in the free subscription over time.

Maybe a better solution would be cross-compiling to arm64 on the current macOS runners. I will leave this open for someone else to implement and test locally on Apple silicon hardware.

christian-rauch commented 4 months ago

The CI pipeline now tests on macos-14-arm64 (https://github.com/stevenlovegrove/Pangolin/pull/935) and shows no issues.

JetForMe commented 4 months ago

So sorry, I completely missed your reply about the cost of the runners!

DeoLeung commented 2 months ago

I just build v0.9.2 and v0.9.1 on m1(14.5) and experienced the same issue, any idea on how to fix it?

any idea on how to fix it?

Hard to say without further information. Are you following the instructions to install the dependencies? The CI pipeline for macOS arm64 (https://github.com/stevenlovegrove/Pangolin/actions/runs/10222724033/job/28287848313) runs successfully.

I don't have access to macOS hardware and rely on the CI for testing. If you can reproduce this on the CI, I can check if there is something wrong with the installation scripts for the dependencies.
