Executable wasm files on Linux

[mgattozzi]

I managed to get wasm files as executables on Linux. I'll do a blog post and write up more about it later, but now it's possible so it would be interesting to see what we can do to explore this space even more.

@pepyakin I ended up using wasmi for this to invoke a binary file's "main" function. I've been trying to pass memory addresses such as strings across boundaries in order to print stuff out but that segfaults so all I can send back is numbers. I'm wondering if this is either a limitation of the interpreter or the environment? I'm not really sure but it would be cool if we could get println to actually work.

@mgattozzi That sounds as something possible for me, so I think that I misunderstood you. Can you give me an example? Share the code?

@pepyakin I'm going to do a write up today and post the code with a more detailed explanation! I'll ping you when I have it done

I'm interested in this too, could you please post it here?

[mgattozzi]

That is the plan! Mostly want to coordinate around this because there's some things that kind of tie into #16

https://github.com/cervus-v/cervus exists as well which seems related.

i'm not certain that this thread is the right place/way to track this. i think new wasm runtimes can be brought up in the News issue. currently a wasm runtime is not on this working group's roadmap. if/when it is, we'll find a place for this convo.
