Hi, Thank you for the diff. I tried it but it does not solve the problem. I had a look at proc-macro-srv-cli and the sysroot-abi needs to be enabled: https://github.com/rust-lang/rust-analyzer/blob/master/crates/proc-macro-srv-cli/src/main.rs#L25 I tried to build with this feature enabled but it needs other features that are not available on stable release channel. Here is the error message I got: error[E0554]: `#![feature]` may not be used on the stable release channel --> crates/proc-macro-srv/src/lib.rs:14:12 | 14 | #![feature(proc_macro_internals, proc_macro_diagnostic, proc_macro_span)] | ^^^^^^^^^^^^^^^^^^^^ error[E0554]: `#![feature]` may not be used on the stable release channel --> crates/proc-macro-srv/src/lib.rs:14:34 | 14 | #![feature(proc_macro_internals, proc_macro_diagnostic, proc_macro_span)] | ^^^^^^^^^^^^^^^^^^^^^ error[E0554]: `#![feature]` may not be used on the stable release channel --> crates/proc-macro-srv/src/lib.rs:14:57 | 14 | #![feature(proc_macro_internals, proc_macro_diagnostic, proc_macro_span)] | ^^^^^^^^^^^^^^^ For more information about this error, try `rustc --explain E0554`. error: could not compile `proc-macro-srv` (lib) due to 3 previous errors I am not sure there is a way out of this. Anyway, the error generated by rust-analyzer can be silenced with the unresolved-proc-macro setting: https://rust-analyzer.github.io/manual.html#unresolved-proc-macro I consider this as kind of solved. Thank you, Regards, Hukadan
