I Followed the wiki to setup Rust but I kept getting linking errors saying ld didn't recognize output, so I visited the Rust docs. It mentions that LLD has to be used when using -C linker-plugin-lto. So I switched to Clang+LLD, but now I get different errors.

When running
Code:
emerge -avuDNt dev-lang/rust

I get this.

Relevant files in /etc/portage:

    /etc/portage/env/O3.conf
    Code:
    COMMON_FLAGS="${COMMON_FLAGS} -O3"
    CFLAGS="${COMMON_FLAGS}"
    CXXFLAGS="${COMMON_FLAGS}"
    FCFLAGS="${COMMON_FLAGS}"
    FFLAGS="${COMMON_FLAGS}"

    /etc/portage/env/compiler-clang-lto.conf
    Code:
    RUSTFLAGS="-C target-cpu=native -C opt-level=3 -C link-arg=-fuse-ld=lld -C linker-plugin-lto"
    LDFLAGS="${LDFLAGS} -fuse-ld=lld"

    CC="clang"
    CXX="clang++"
    CPP="clang-cpp"
    AR="llvm-ar"
    NM="llvm-nm"
    RANLIB="llvm-ranlib"

    /etc/portage/package.env
    Code:

    sys-devel/llvm O3.conf
    sys-devel/clang O3.conf

You probably ran out of RAM. You'll need to add swap and probably also reduce your -j jobs. On 64-bit this should finish, but slowly... Or just use rust-bin.

32-bit, it could fail and we don't have a solution yet.
