error: aborting due to previous error

So I get the same error I guess trying to target both asmjs and wasm. I guess I don't know if I did something stupid, or if it's a real issue with emscripten...

Here is emcc --v

Seems like #39355 is related? cc @brson

I don't see anything obviously wrong with any of the suffixes being passed to emcc. I might guess that emcc has added new validation that doesn't anticipate being passed 'rlib's.

Can confirm this behaviour with the same version of emcc. Fixed it by upgrading the latest release.

I'm getting the same issue under the new version as well

That's because it's still version 1.22.1.

Thanks for pointing that out I realised I wasn't able to compile from another directory, turns out I'm a Linux noob and it was an issue with my environment variables.
The fix was running ./emsdk_env.sh and compiling my project under the same directory.

I don't see this with a recent emscripten, so I'm going to close.
