The recommendation (coming from rust-lang/rust#130062) for Linux hosts is using C compiler driver as a linker, which is able to find system-wide libraries. Using linker binaries directly in `-C linker` (e.g. `-C linker=rust-lld`) often results in errors like: ``` cargo:warning=error: linking with `rust-lld` failed: exit status: 1ger, ppv-lite86, libc... cargo:warning= | cargo:warning= = note: LC_ALL="C" PATH="/home/vadorovsky/.rustup/toolchains/stable-x86_64-un cargo:warning= = note: rust-lld: error: unable to find library -lgcc_s cargo:warning= rust-lld: error: unable to find library -lc cargo:warning= cargo:warning= cargo:warning= cargo:warning=error: aborting due to 1 previous error ``` Not touching the linker settings is usually the best approach for Linux systems. Native builds pick up the default C toolchain. Cross builds default to GCC cross wrapper, but that's easy to supress with clang and lld using RUSTFLAGS. However, `-C linker=rust-lld` still works the best on macOS, where Rust toolchains come with unwinder and runtime and there is usually no need to link system libraries. Keep setting it only for macOS. Fixes #907 |
