Errors while executing hello world example with lucetc-wasi about lucet HOT 5 CLOSED

Hi!

lucetc-wasi is the compiler. It cannot run code.

The resulting .so (or .dylib) file must be run with lucet-wasi, which is a different tool.

from lucet.

Wow! Thank you for such a fast answer! I'm reinstalling the Lucet so will try as soon as it is installed.

And what about the Wasmtime? Is there a way to pass compiled .so object or similar to avoid compilation by JIT compiler of Wasmtime?

from lucet.

You're correct, invoking the lucet-wasi tool solves the issue with errors.

From what I read in the meantime, I've got an impression that there is no way (at least for now) to use some sort of AOT with the Wasmtime, and I had am impression that Wasmtime is the runtime used by Lucet but after searching I think Wasmtime is used to provide some files for build support.

Wasmtime includes a cache: https://bytecodealliance.github.io/wasmtime/cli-cache.html - Once code has been cached, it doesn’t need to be recompiled any more.

Thank you!

I've done some tests and according to Valgrind Massif and got a bit surprised since consecutive executions with cache enabled still got almost 4MiB, when comparing with Wasmtime JIT (cache disabled) 4.4MiB... It is improvement, but not as much as I was expecting.

Check this out:
1st cache enabled execution:

2nd cache enabled execution:

3rd cache enabled execution:

And now Wasmtime, cache disabled:

But this is way beyond Lucet's responsibility!

Thank you again jedisct1! You really helped me a lot.

I think this issue can be closed, you prefer me to close it?
