Linker `arm-linux-gnueabihf-gcc` not found in MacOS and Win 10

[hajsf]

I'm trying to build for RPi from Mac,

Started by:

$ rustup target add armv7-unknown-linux-gnueabihf

Creating file .cargo/config with content:

[target.armv7-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc"

And running the:

$ cargo build --target armv7-unknown-linux-gnueabihf

But I got the below error:

error: linker `arm-linux-gnueabihf-gcc` not found
  |
  = note: No such file or directory (os error 2)

Tried the below after that, but nothing worked:

$ brew install arm-linux-gnueabihf-binutils
$ brew tap osx-cross/arm
$ brew install arm-gcc-bin
$ brew install llvm

But everytime I run:

$ which gcc-arm-linux-gnueabi

I get nothing, and keep getting the same error above.

I tried using musleabihf as alternate gnueabihf, but the generated binary failed to work at RPi

[target.armv7-unknown-linux-musleabihf]
linker = "arm-linux-gnueabihf-ld"

I'd a look at this as well, but nothing about MacOS

It looks I made copy of wrong binary in while testing the musleabihf it is working in real, as bellow:

$ brew install arm-linux-gnueabihf-binutils
$ rustup target add armv7-unknown-linux-musleabihf

In .cargo/config

[build]
target = "armv7-unknown-linux-musleabihf"
[target.armv7-unknown-linux-c]
linker = "arm-linux-gnueabihf-ld"

With simple src/main.rs

fn main() {
    println!("Hello, Raspberry!");
}

Then things are fine:

Hasans-Air:rpi hasan$ cargo build

For Win 10 I was able to get the linker from here, and run:

rustup target add armv7-unknown-linux-gnueabihf

Creating file .cargo/config with content:

[build]
target = "armv7-unknown-linux-gnueabihf"

[target.armv7-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc"

And with simple src/main.rs:

fn main() {
    println!("Hello, Raspberry! from Win 10");
}

I was able to get things done
