在 Apple M1 中，当我为 Linux X86_64 编译 Rust 代码时，我收到错误 ld: unknown option: --as-needed：

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

我已经安装了x86_64-unknown-linux-gnu 工具链。

这有点类似于stackoverflow.com/questions/40424255/…，所以也许也可以作为副本关闭。

【解决方案1】：

您可能缺少正确的链接器。

安装 GNU 编译器集合：

brew install gcc

并将其添加到.cargo/config

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

【讨论】：

【解决方案2】：

$ 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"
