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:
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?
