unknown import, Code: 0x62

I'm using the bindgen example to run my rust code. I have followed all steps to setup my environment.

❯ ./bindgen_funcs rust_bindgen_funcs/pkg/rust_bindgen_funcs_lib_bg.wasm

unfortunately I cannot make sense on any of those errors.

EDIT:

I now followed the instructions in joey to install everthing and now face

./bindgen_funcs: symbol lookup error: ./bindgen_funcs: undefined symbol: WasmEdge_ModuleInstanceListMemory

Hi @chris-aeviator
Looks like there are two different errors. However, it could be related to errors.

The first is that the wasm file wants to call an external function env::return_error which is not in the standard, so it failed.
The second is that the given parameters of __wbindgen_malloc is wrong. We will need more information to figure out this. Could you provide the application source code?

And for the edited one, Please make sure the WasmEdge version is the same. We have several breaking changes during 0.8.x, 0.9.x, and 0.10.x. If the version is not matched, then you will receive that some WasmEdge API is not found or not matched.

Could we find another way than sharing the complete code, I'd have to do quite some redacting for that?! I'm doing a bunch of calculations on CSV and JSON data, I tried all combinations of passing it as strings as shown in the example to reading from files, bindgen, and actually it seems not to be related to this actual error, since the error happens before any println output in my code.

The only external crates I'm using are:

  suborbital = "0.13.1"
  csv = "1.1"
  geo = "0.17.1"
  geo-types = "0.7.4"
  serde = { version = "1", features = ["derive"] }
  serde_json = "1"

Sure thing. We only need the minimum reproducible code snippets.
And I will check if there is any crate that is not compatible with standard wasm/wasi. Thanks.
