Container failing on wokwi-server compile

[mortenhauan]

In VSCode on starting DevContainer for first time, it stops with the following error:

I can see that it is related to this issue in wokwi-server. I tried adding ENV RUSTFLAGS="--cfg tokio_unstable" to the Dockerfile. That gets around the no JoinSet in task error, but it still failes on the other errors.

[mortenhauan]

Removing wokwi-server from --extra-crates "ldproxy cargo-espflash wokwi-server web-flash" \ in Dockerfile fixes it for now.

[MabezDev]

You also need the --locked flag, see https://github.com/MabezDev/wokwi-server#installation. This was fixed in this Dockerfile, but didn't get updated here.

Thank you @MabezDev. My current working Dockerfile is this:

Which platform are you using? I assume you are using aarch64 (m1), is that correct? As you mentioned, at this moment, installing wokwi-server via --extra-crates argument of the installer fails as it does not set RUSTFLAGS and does not use --locked. This is already fixed, but since the Dockerfile pulls the installer from the releases, those changes are not present, I would recommend using your Dockerfile as a temporary solution, and waiting for 1.62.0.0 release which will probably come up next week and would solve the issue.

[MabezDev]

Also https://github.com/tokio-rs/tokio/issues/4535 is nearing stabilization, so we won't need the unstable cfg soon.

[mortenhauan]

I'm using M1 yes, @SergioGasquez. It is no problem using my own Dockerfile as a temporary solution for now.

I'm using M1 yes, @SergioGasquez. It is no problem using my own Dockerfile as a temporary solution for now.

Great, we expect to have 1.62.0.0 finished by the end of this week, I'll keep you updated!

[SergioGasquez]

Update: Release 1.62.0.0 is out! Using your custom Dockerfile should no longer be required, I'll try to do some testing later on today to confirm that is working fine Update2: Just tested it using my M1 and seems to be working fine!

Could you give it a try and report back the results with the new installer @mortenhauan? Thanks!

[SergioGasquez]

Hello @mortenhauan, did you have a chance to confirm that is working for you? I would like to close the issue as it should be already fixed with the 1.62.0.0 release
