Linkage error when building for `aarch64-pc-windows-msvc`

[rami3l]

As a part of rust-lang/rustup#3898, we (the Rustup team) have tried to introduce rustls-platform-verifier to Rustup by adding the following into our Cargo.toml:

rustls-platform-verifier = { version = "0.3", optional = true }

... which, at the time of writing, points to rustls-platform-verifier 0.3.1 released 2 months ago.

When cross-compiling for aarch64-pc-windows-msvc however, the following error was generated:

Hi there @rami3l. This looks like an error with aws-lc-rs, which is the default cryptography provider for rustls in the most recent versions but not rustls-platform-verifier. My thought process here is the following:

• The logs you linked are full of undefined C symbol errors coming from the libaws_lc_sys-2799e0ca1159a8ce.rlib static library.
• 1Password, within the last month, has successfully built rustls-platform-verifer for aarch64-pc-windows-msvc using the ring cryptography backend. It was shipped as part of an ARM64 Windows alpha release.

It may be worth trying to activate the ring backend feature of rustls in rustup's dependency tree to see if the issue goes away.

Does this happen with just rustls+aws-lc-rs, or is rustls-platform-verifier also required to reproduce the failure?

[complexspaces]

I was able to compile and run the tests for rustls-platform-verifier in an ARM64 Windows 11 VM with the aws_lc_rs backend earlier today. The steps I took to setup the environment were:

• Installed the latest CMake from their website
• Installed the latest Ninja from GitHub releases
• Download the latest Visual Studio 2022 Tools installer
• Installed these components:
  • Windows 11 SDK
  • MSVC v143 C++ ARM64 build tools

I then:

• Edited rustls-platform-verifier's main branch to use aws_lc_rs everywhere ring currently is
• Ran cargo test.

With this setup, I don't get the errors you reported FWIW. @ctz mentioned this in the project Discord but it looks like there isn't a compatible ucrt available to your build since all the missing symbols should be coming from it. I saw the VS installer install a ARM64 ucrt implementation, so maybe that's part of what's missing?

@complexspaces Thanks! We're doing cross compilation (since we don't have access to the ARM64 Windows runners yet) so that could very possibly be the case. I will definitely investigate further into this one.

If I use the ring backend then the problem is indeed gone, see rust-lang/rustup#3903. However we are inclined to using aws-lc for the moment due to rust-lang/rustup#3820 even if that means a whole lot more CI config 😢

Also looks like #102 might be relevant here.

@rami3l Can you weigh in on this aspect w.r.t your cross compilation experience? Is it specific to adding rustls-platform-verifier into the mix?

@cpu I'm not sure... Now that rustls-platform-verifier has been included into Rustup the only way to know would be temporarily reverting it in another branch and trigger the CI, however I'm a bit tired handling all this regarding rustls right now... I'll ping you back when I'm ready to give this another try. Sorry 🙇‍♀️

[cpu]

Understood! Thanks for your help :-)

If myself or someone else has time to set up a similar cross-compilation environment it would be helpful to separate whether it's an issue with this repo, or rustls+aws-lc-rs generally. If it's the latter I think working with the aws-lc-rs upstream would be the next step (IME they seem quite responsive w.r.t build issues). If it's the former we should do more investigation here.

@complexspaces @cpu Just made another test PR at rust-lang/rustup#3917. Looks like aws-lc is the origin of this issue this time. I think it's reasonable to transfer the issue to aws/aws-lc-rs#453.

Thanks anyway everyone, and especially for your test in #101 (comment)!
