add this to .cargo/config.toml

For Windows (dont work for modules with native compilation i.e openssl)

[target.x86_64-pc-windows-msvc] rustflags = ["-C", "target-feature=+crt-static"]

[target.x86_64-unknown-linux-musl] linker = "rust-lld"

https://releases.linaro.org/components/toolchain/binaries/

[target.aarch64-unknown-linux-gnu]

linker = "C:/app/gcc/gcc-linaro-5.5.0-2017.10-i686-mingw32_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc-5.5.0.exe"

linker = "C:\app\gcc\gcc-linaro-7.5.0-2019.12-i686-mingw32_aarch64-linux-gnu\bin\aarch64-linux-gnu-gcc-7.5.0.exe"

[target.armv7-unknown-linux-gnueabihf] linker = "C:\app\gcc\gcc-linaro-7.5.0-2019.12-i686-mingw32_arm-linux-gnueabihf\bin\arm-linux-gnueabihf-gcc.exe"

For WSL (OK for native modules)

but have to use vendored i.e. openssl-sys = { version = "0.9.72", features = ["vendored"] }

https://howtoinstall.co/en/gcc-aarch64-linux-gnu sudo apt install aarch64-linux-gnu-gcc

[target.aarch64-unknown-linux-gnu] linker = "aarch64-linux-gnu-gcc"
