maturin build fails on CentOS 7 about maturin HOT 4 CLOSED

I've investigated a bit, IMO the wasmedge C API didn't not expose any error status in WasmEdge_PluginLoadFromPath makes it hard to look further.

https://github.com/second-state/wasmedge_plugin_rust_sdk/blob/22fab4633bd8b0b653da98a00c5c267ba1924337/wasmedge_sys_ffi/src/ffi.rs#L1819

It definitely has hit some error condition but without proper error reporting, you're better investigate by yourself because I'm not using WasmEdge and I'm not interested in debugging by reading a lot of WasmEdge ffi code.

• Build with maturin build (Failed)

I don't see any failure that's directly related to maturin since the wheel is correctly built, the plugin load failure seems like a user code or runtime environment issue.

Closing because nothing we can fix in maturin here.

@messense Thanks for your reply. As I mentioned above, when I use maturin develop, the wheel works and prints out

Hello, world!
Plugin count: 1
Plugin names: ["wasi_nn"]

However, when I use maturin build and install the wheels manually, it fails to print the same info as before:

Hello, world!
Plugin count: 0
Plugin names: []

No change happened between these two compilations. So I don't know why the wheels built with develop and build behave differently.

Thank you for the help. I'll check the issue further.
