Rust crate does not work with MSVC about blst

[dot-asm]

The Rust crate blst does not compile when using MSVC as the compiler.

This is a bit misleading, as the problem is not as general. It doesn't work specifically with 32-bit MSVC as the compiler.

If you have to build for 32-bit Windows (why?), add clang in the Visual Studio installer and execute cargo at x86 Tools Command Prompt. For reference, the prompt gives you 32-bit clang-cl on your %PATH%. This, 32-bit clang-cl on %PATH%, can be achieved by any other means.

I'm just trying to cargo run some code using BLS locally, not build an executable for 32 bit Windows. I'm on a 64 bit machine (Ryzen 5600X).

I'm using PowerShell inside of VSCode, which is a pretty typical development environment. Not sure why the shell I'm using plays any role in whether or not blst will compile?

Then your Rust installation is configured with i686-pc-windows-msvc as default target, instead of apparently expected x86_64-pc-windows-msvc. I naturally don't know how you installed and configured Rust on your computer, but you have the keyword now. Either ensure that x86_64 is the default, or pass --target=x86_64-pc-windows-msvc on cargo command line :-)

Weird, I'm on a 64-bit version of the OS on 64-bit hardware, so I'm really not sure why it decided to default to i686. Setting the target did indeed work.

Thanks for the help.
