We don't currently support building with stable (but see #284). If you install the toolchain provided in rust-toolchain, do you get the same errors?

[carlocab]

IIUC you require the nightly-2020-11-09 rustc, which predates Apple Silicon support (added in Rust 1.49), so that won't work for Apple Silicon either.

Are there plans to support building with a stable version of the Rust toolchain?

[jrose-signal]

"We don't currently support building with stable" hasn't changed, but we can roll forward to a new nightly soon. (We don't have time for it right now, but soon, along with updating dependencies.)

[jrose-signal]

#323 includes the new nightly and explicit testing of the M1 iOS simulator, so I suspect everything should work with an M1 host now. Can you verify?

Thanks for the responses, I tried to build it today with a new issue:

   Compiling polyval v0.5.1
   Compiling ctr v0.7.0

Looks like polyval is still missing Apple Silicon support - I will try to create an issue there.

Polyval (https://github.com/RustCrypto/universal-hashes/tree/master/polyval) is building quite fine even with older tags

[chrstnwhlrt]

Changing the installation method to the office rustup (used homebrew before) solved the issue - it's now building fine using the stable channel of rust: rustc 1.53.0 (53cb7b09b 2021-06-17)
