Gems with native extensions

[danini-the-panini]

Can we use gems with native extensions? I've read somewhere that it is possible, and it makes sense for it to be possible. However, I'm struggling to get even a basic example to compile. There doesn't seem to be any documentation as to how to set it up.

If I try statically linking, I get the error "Could not create Makefile due to some reason". Checking the mkmf log does not yield any useful information.

If I try dynamically linking with RUBY_WASM_EXPERIMENTAL_DYNAMIC_LINKING, I get the error ld: unknown option: -Xlinker

I've created a minimal repo to test: https://github.com/danini-the-panini/rbwasm-foo

If it makes a difference, I'm running on Apple silicon.

Ok I tried on linux x86_64 and I get the same errors, although the dynamic linking says ld: Error: unable to disambiguate: -Xlinker (did you mean --Xlinker ?)

It's still experimental, and I need to do some upstreaming works. Stay tuned 😉

ok, is there any way I can help?
