[Selyatin]

Issue was fixed once I used the compiler & linker from the musl-cross-homebrew-formula, so not sure if it's still relevant or not.

Here's the old formula that I used.

[franklinblanco]

@Selyatin Hey, have you tried compiling for x86_64? I had to move like 18 microservices to use rustls-tls instead of openssl on all dependencies to avoid this issue.

[Selyatin]

@franklinblanco works fine on x86_64, now it works just fine on aarch64 as well after changing the formula. So I'm thinking of closing the issue.

[Selyatin]

Yeah well I'm getting the same issue now, no idea why.

[jmg-duarte]

I spent all day tracking this down. In my case, I had a aarch64 build failing inside a Docker container.

After checking every openssl related dependency on my project, I found we we're using cc 1.0.84 which was yanked, forcing 1.0.83 solved this issue.

I hope this helps some of you!
