Linker error when cross compiling on Linux for Windows

[WyattEnrich]

Hello,

I am using winapi to validate the authenticode signature on executables (via https://docs.rs/codesign-verify/). When I cross compile on Mac for Windows, it works fine; when I cross compile on Linux for Windows, it fails with a linker error:

note: /usr/bin/x86_64-w64-mingw32-ld: cannot find -lWintrust

A simple test case follows:

Cargo.toml:

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

[dependencies]
codesign-verify = "0.1.2"

main.rs:

extern crate codesign_verify;

use codesign_verify::CodeSignVerifier;

fn main() {
	let path = "C:/Windows/explorer.exe";
	CodeSignVerifier::for_file(path).unwrap().verify().unwrap();
	println!("Success");
}

On the build system (Linux) I have installed Rust, added the x86_64-pc-windows-gnu target, and installed mingw-w64.

rustup target add x86_64-pc-windows-gnu
sudo apt-get install mingw-w64

I build with command:

cargo build --target=x86_64-pc-windows-gnu

The error log is attached:

Do you have any idea how to get around this? I can't think why an OSX build machine would work while Linux does not. We unfortunately need to build on our Linux dev server.

Thank you very much!

This turned out to be an issue with codesign-verify. Sorry for the ticket!
