Apple M1 issues

[jjoliveira]

I'm having some problems with lilliput on my M1 machine.

Running go get github.com/discord/lilliput returns me:

My machine go version and arch is as follow:

❯ go version
go version go1.17 darwin/arm64

Is this a known issue? Is there any workaround?

Cheers

I'm working on a fix around this issue, so far I have successfully built it on linux/arm64, which can be used with Docker on Mac without performance degradation. For the Apple M1, it seems more challenge. I'm happy to create a PR after that. But this would potentially increase the cost of all upcoming changes, the maintainers have to update all the libs for linux/drawin * amd64/arm64.

Just link my forked version here for anyone who has interests.

Thank you @kenshin54! It looks like you've got it workin on Apple M1 and opened the PR: #98 . I've tested it and it seems to work for me on my Mac natively (darwin/arm64) and in docker (linux/arm64).
