Cross compile error `ld: unknown option: --as-needed`

Question

In Apple M1, when I compile my Rust code for Linux X86_64, I get an error ld: unknown option: --as-needed:

error: could not compile `helloworld` due to previous error

I had already installed the x86_64-unknown-linux-gnu toolchain.

This is somewhat similar to #40424755, so maybe could be closed also as a duplicate. – Tollmann

Answer 1

$ brew tap SergioBenitez/osxct
$ brew install x86_64-unknown-linux-gnu

# .cargo/config.toml
[build]
target = "x86_64-unknown-linux-gnu"

[target.x86_64-unknown-linux-gnu]
linker = "/usr/local/bin/x86_64-unknown-linux-gnu-gcc"

Answer 2

You may be missing a proper linker.

Install GNU compiler collection:

brew install gcc

And add it to .cargo/config

[target.x86_64-unknown-linux-gnu]
linker = "/usr/local/bin/gcc-<version>"
