I'm trying to create a rust project using the bellperson crate. Before even actually implementing it in my code (instead of the bellman crate), I just tried building with it, but I'm getting an error.

My Cargo.toml:

[package]
name = "temp1"
version = "0.1.0"
edition = "2018"

[dependencies]
bellperson = "0.9.2"

my main.rs:

fn main() {
println!("yay");
}

the error:

warning: cl : Command line warning D9024 : unrecognized source file type './asm/mul_4.S', object file assumed
warning: cl : Command line warning D9027 : source file './asm/mul_4.S' ignored

error: failed to run custom build command for `fff v0.2.2`

Caused by:
  process didn't exit successfully: `C:\Users\dana\Desktop\project\save to disk\target\debug\build\fff-733f5e53c9fbd315\build-script-build` (exit code: 1)

any ideas on how to solve this, or why is it happening? thanks!

--edit-- tried running it using Cygwin, ran CC=gcc AR=gcc cargo build, got a similar error:

--2nd edit-- tried with MinGW, ran cargo build. still doesn't work, still a similar issue:

  • Looks like the `fff` crate contains an assembly file that can't be built with MSVC. You probably need to install a GNU toolchain, e.g. with cygwin. I haven't used Windows in 20 years, so I won't be able to help with the details. – Sven Marnach Jul 14 '20 at 09:40
  • tried with Cygwin, ran CC=gcc AR=gcc cargo build, still doesn't work :( – justme1205 Jul 14 '20 at 11:27
  • Looks like your target triple is still set to `x86_64-pc-windows-msvc`, so the `cc` crate will pass options suitable for the MSVC tool chain. I don't really know whether you can compile Rust on cygwin, or whether you should use MinGW instead. Google will probably know better than someone who never uses Windows. – Sven Marnach Jul 14 '20 at 12:27
  • Google found this: https://stackoverflow.com/q/47379214 So maybe you are better off with MinGW, which also gives you a GNU toolchain. – Sven Marnach Jul 14 '20 at 12:28
  • tried with MinGW - still doesn't work :( – justme1205 Jul 14 '20 at 13:40
  • The last log you pasted uses MSVC, not MinGW. – Sven Marnach Jul 14 '20 at 14:35
