WASM #1

Open jpeddicord opened 6 years ago

jpeddicord commented 6 years ago

Yes, really. Not so much for use in a browser, but to make use in Node less painful.

Alternatives to that root problem:

Use neon, a cool project in its own right
Write C-style bindings

Neither are huge upfront cost, but are a maintenance load and are more difficult to use downstream.

...also I think it'd be really neat to have an in-browser demo of this library.

Thought dump:

wasm32-unknown-unknown is not a great goal for now; there's too many dependencies that can't work withough e.g. libc at the moment
emscripten seems OK. more work to bootstrap, but using emsdk wasn't too bad, and everything builds successfully.
will still probably omit filesystem-related things during wasm compile, though.

Progress made here! There's some stuff in the wasm directory in master. It's very basic and not at all supported, but I'm hoping to iterate quickly as some more dependencies become wasm-capable.

After installing apt packages clang, and gcc-multilib, I am now stuck on an error when rust try to compile zstd-sys error: unable to create target: 'No available targets are compatible with this triple.'

You mentioned that you were able to use emscripten to build a wasm binding for this library. Can you give more information please?

jpeddicord commented 4 years ago

I've in fact been running into this issue myself; it's been a while since I got this to work out successfully. If I recall correctly, the options were to use emsdk to build with emscripten (which doesn't really fix the wasm32 target here) or to build LLVM yourself with the wasm32 stdlib enabled. The packages on Ubuntu don't ship with that; the packages on Arch might. I do want to dig into this more.
