I try the diff from semarie@ to build proc-macro-srv-cli crate and added sysroot-abi feature (needed by proc-macro-srv-cli, see https://github.com/ rust-lang/rust-analyzer/blob/master/crates/proc-macro-srv-cli/src/ main.rs#L25). Same errors with '#![feature]' not supported with Rust stable release for proc-macro-srv crate. Laurent
