@kamikaze The commit that fixes this isn't in the pypi release yet. Try using git+https://github.com/MagicStack/asyncpg.git instead of specifying a pypi version. That should use the latest code as long as you have git installed and worked fine on aarch64 for me.

it seems it doesn't pull submodules... nah...

Oh yeah - I usually clone, init submodules and build a wheel to reuse it as the ARM machines I use are very weak and take many minutes to compile it. Have you tried that yet?

yep, it works. but is this project alive? I would like to get it packed and released for automated stuff. Manual installation is a no go in real world :)

Alive and well.

We use Travis for testing and releases, feel free to add a build target to CI.

@elprans I think he was referring to releasing the current codebase as a new version to include the updated pgproto in upstream. I would be happy to work on the Travis target for aarch64 if you wouldn't mind

@kamikaze there are now aarch64 wheels on pypi for version 0.21 so I think this is resolved 👍
