[Web] When performing inference with ONNX Runtime in C++, using the libonnxruntime_webassembly.a static library, but encountering an error during the session.run() call in an HTML5 environment, the error message is: "Uncaught (in promise) 50699072".

Describe the issue

I want to perform inference using ONNX Runtime in C++, and call it from H5 using JS. Loading the model and outputting model-related information work fine, but I encounter an error during the session.run() operation. I'm not sure what specifically is causing the issue. Could you provide me with some suggestions?

To reproduce

I built libonnxruntime_webassembly.a using the following command：
./build.sh --config Release --build_dir build_wasm --skip_tests --build_wasm_static_lib --enable_wasm_simd --enable_wasm_threads --skip_submodule_sync --allow_running_as_root --disable_wasm_exception_catching --disable_rtti

Urgency

No response

ONNX Runtime Installation

Built from Source

ONNX Runtime Version or Commit ID

1.17.0

Execution Provider

'wasm'/'cpu' (WebAssembly CPU)

Please remove flag --disable_wasm_exception_catching --disable_rtti and build again. Should show some error message.

I recompiled as you suggested and then ran it and got an error specific message as follows:
Uncaught (in promise) RuntimeError: null function or function signature mismatch

I didn't see this error before. To further investigate the issue, you may need to add "-s DEMANGLE_SUPPORT=1" in your link flags to check the function names in the stack.

According to your suggestion, I added -s DEMANGLE_SUPPORT=1 during compilation, and a warning appeared:
em++: warning: DEMANGLE_SUPPORT is deprecated since mangled names no longer appear in stack traces [-Wdeprecated]

Is there a version correspondence or match between emscripten and onnxruntime?

[fs-eire]

we are now using emsdk 3.1.51 in onnxruntime main branch.

I use emsdk 3.1.54,will this have any impact?

[fs-eire]

I am not sure. Maybe you can use 3.1.51 to take a try

Can you provide a simple C++ demo based on ONNX Runtime? I want to test if it can run successfully with libonnxruntime_webassembly.a. Is it possible that there's an error in my C++ inference program?
