Build issue on ARM macOS about pqcrypto HOT 6 CLOSED

Hi, can you try just building the native libraries (so in this case crypto_kem/kyber512-90s/aarch64) in PQClean?

from pqcrypto.

Got it. The bug was simpler than expected: there simply is no kyber512-90s/aarch64 to speak of!

There's only clean and avx2 impls. So something in the build script is not checking whether the target exists.

from pqcrypto.

Ah, right! The code isn't detected but we have a Yaml file that keeps track of all the available implementations for which we need to generate code. Clearly I accidentally claimed support for Aarch64 for Kyber-90s, even though there was no implementation.

(If you need it, there's probably a reasonable way to patch the Kyber-aarch64 code in PQClean to use the 90s crypto and we would merge that PR)

This issue seems to be unresolved, as I'm getting similar errors on freshly checkout code.

The following warnings were emitted during compilation:

Looks like a .a file should be been created but wasn't, but I don't know what code was run to try to compile something.

from pqcrypto.

Seems to work, I had forgotten about the submodules (git submodule update --init).

I am confused though, as pgcrypto-kyber is a dependency of wasi-crypto, and wasi-crypto is a dependency of Wasmtime when compiling with cargo build --features wasi-crypto. Yet for some reason, it (compiling Wasmtime with Wasi-Crypto) works on Linux but fails on macOS with an error similar to one above. Maybe cargo isn't checking out the submodule used by a dependency as it should? But would it work on one OS but not the other?

from pqcrypto.

Okay there's not exactly enough information to go on here, and I don't really know how WASI works. I'm also afraid that I have time to get in to that I'm afraid.

However, if you or anyone else does manage to figure out what's going on with your problem there, I'm very welcoming to contributions that make the crates more reliable.
