ARMv8 compatibility: CI and cross-compiling?

[thomwiggers]

At the moment, this crate is only expected to work on intel. We might want to set up CI for ARMv8 and next figure out the relevant CMake flags etc.

I use the oqs-sys crate in wolfssl-sys. I've got an example that builds and tests post quantum with WolfSSL here: https://github.com/expressvpn/wolfssl-sys

It builds happily on an M1 mac as an arm64 executable.

Though I just discovered that the ports on the test site aren't fixed, so my test breaks if you don't update the port 😄

[thomwiggers]

That's good to hear; but I don't know what you mean by "the ports on the test site"?

[thomwiggers]

Also I think that cross-compiling to ARMv8 is something that we should probably support but I'm not too experienced with how to set up cmake for that.

[thomwiggers]

Okay for the latter it seems we're blocked on https://github.com/rust-lang/cmake-rs/pull/158 at least.

Ah sorry, I have an example app that connects to test.openquantumsafe.org on port 6051. At the time of writing, it was the port used for the equivalent of WOLFSSL_P521_KYBER_LEVEL5. Since then though (I guess it was restarted?) the assigned port numbers have changed, so this example no longer works.

I just need to find out if there's a way to programmatically get that port lis, if I need to scrape the page or just make the port a command line argument 😊

[thomwiggers]

Ah right. That's more of a question for the liboqs repository I think.

@expressvpn-pete-m : Sorry I only see this comment now:

There is: See the current port assignment JSON here.

Is it possible that my issue here is related to this? I'm trying to use armv8 via cross compiling, too.
