How to use the compiled WASI artifacts?

[AlmogBaku]

Hi,
I'm trying to figure out how can I use the compiled WASI artifact, I tried the following but it threw me an exception;

$ wasmtime run --env PYTHONPATH=/builddir/wasi/$(cat pybuilddir.txt) --mapdir /::../../ --  python.wasm 
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Python path configuration:

  PYTHONPATH = '/builddir/wasi/build/lib.wasi-wasm32-3.11'

  user site = 1
  safe_path = 0
  import site = 1
  is in build tree = 0
  stdlib dir = '/usr/local/lib/python3.11'
  sys._base_executable = ''
  sys.base_prefix = '/usr/local'
  sys.base_exec_prefix = '/usr/local'
  sys.platlibdir = 'lib'
  sys.executable = ''
  sys.prefix = '/usr/local'
  sys.exec_prefix = '/usr/local'
  sys.path = [

    '/usr/local/lib/python311.zip',
    '/usr/local/lib/python3.11',
    '/usr/local/lib/python3.11/lib-dynload',
  ]

3. I also tried to put the "build" files in the same dir

1. Start with a clean checkout or clean your checkout with git clean -xdf
2. unzip wasm-main.zip into the top directory of your checkout
3. run wasmtime run --dir . -- python.wasm

The additional env var and mappings are only needed for out-of-tree builds.

Should we consider building a self-contained WASI binary for people to play with? I had someone at work run into the situation where they initially didn't expect to need the repo checkout. Otherwise should we record the git commit that the WASI binary was built against so people can get a matching checkout?

Self contained make a lot of sense, especially since its intended to be embedded as part of some program
