Rust sdk does not work, cannot create an instance "thread signal env initialized failed"

[macko99]

Hello, would you be able to help me with creating WAMR containerd shim?

I have created some PR but I end up with one of the errors:

-"thread signal env initialized failed"
-without any error
-"error running start function: Failed to create instance: InstantiationFailure("error while pre-opening mapped directory: invalid map"
-"Running "_start"" then "Error: ExecutionError("Exception: unreachable")"

My module has only the main function defined.
I have tried disabling hardware checks in WAMR since I'm working on the VM, commit

error while pre-opening mapped directory: invalid map

means the wasi argument isn't set correctly. if using iwasm, you might want to use --dir or --map-dir to config WASI.

@lum1n0us I'm using the wamr-rust-sdk

@lum1n0us please take a look at the PR

I do set
let wasi_ctx = WasiCtxBuilder::new() .set_pre_open_path(vec!["/"], vec!["/"]) .set_env_vars(envs.iter().map(String::as_str).collect()) .build();

I have also tried with other dirs, just like in an example, it fails with "Error: ExecutionError("Exception: unreachable")"

To clarify:
-when setting envs by set_env_vars the shim exists with no error or "thread signal env initialized failed"
-when setting set_pre_open_path to "/:/" I get "error running start function: Failed to create instance: InstantiationFailure("error while pre-opening mapped directory: invalid map"
-when setting set_pre_open_path to ".:" I get "Error: ExecutionError("Exception: unreachable")"
