Error compiling on `aarch64-pc-windows-msvc`
Hi,
Thanks for the library, I am having trouble compiling ring:0.16.20 on Windows (I don't usually use windows so this is all very new to me).
I have followed the instructions in BUILDING.md and I think I have installed all the right libraries (VSCode 2022 with the C++ Development workflow and MSVC v142 - VS 2019 C++ ARM64 build tools) but it is quite likely I am missing something.
error: failed to run custom build command for `ring v0.16.20`
Caused by:
process didn't exit successfully: `Y:\git\desktop\target\debug\build\ring-26b79f943f484e4c\build-script-build` (exit code: 101)

I am note sure why rust thinks the host is x86_64 (HOST = Some("x86_64-pc-windows-msvc")) when I check the architecture:
wmic os get OSArchitecture
I get:
OSArchitecture
ARM 64-bit Processor
FYI, I am running Windows 11 on an M1 via Parallels but I don't know if that is relevant.
Any pointers would be much appreciated 🙏
Alright, this was partially a matter of RTFM for me.
Documentations shows you need to set TARGET_CC for cross compile, it also says it uses clang. So it should be worth noting you need clang-cl as your TARGET_CC to cross compile.
However...
There is a bug in the build.rs for 16.20 that causes the compile to fail anyway. This is fixed in the 0.17.0-alpha.11.
Of course, it's alpha... hopefully a full 0.17 will be released.
Thanks! I am going to close this since it seems to be resolved. I'm hoping to make the cross-compiling "just work" in the near future.
