 |
|
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:
| Code: | COMMON_FLAGS="${COMMON_FLAGS} -O3"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}" |

| Code: | RUSTFLAGS="-C target-cpu=native -C opt-level=3 -C link-arg=-fuse-ld=lld -C linker-plugin-lto"

CXX="clang++"
