emsdk 3.1.53 leading to: wasm-ld: error: /home/runner/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/asmjs-unknown-emscripten/lib/libunwind-b74949c4c5c827f2.rlib: archive member 'lib.rmeta' is neither Wasm object file nor LLVM bitcode

[ajgrah2000]

Sorry if this isn't particularly helpful, but emsdk was working a treat until today (was running latest), so thought I'd flag this (just incase it's of some value). I haven't looked for a 'minimal repeatable' case.

emsdk version '3.1.52' is leading to a 'wasm-ld' link error.

 archive member 'lib.rmeta' is neither Wasm object file nor LLVM bitcode

The same build command with 'emsdk version '3.1.52' (all other steps being equal), works as expected.

Please include the following in your bug report:

emsdk install 3.1.53
emsdk activate 3.1.53

Failing command line in full:

Apparently this was fixed upstream in rust: rust-lang/rust#120278

[ajgrah2000]

Thanks for you're impressively fast response (and sorry for the extra noise).
Just adding a comment to confirm that the issue was resolved (as you'd predicted) when I switched to:

rustc 1.77.0-nightly (cb4d9a190 2024-01-30) (was previously using rustc 1.75.0)
emscripten 3.1.53

(I also changed the target to wasm32-unknown-emscripten)
