[GitHub] [tvm] majercakdavid opened a new issue #7734: [Web] tvmjs runtime error when loading, missing "runtime.SystemLib"
majercakdavid opened a new issue #7734:
URL: https://github.com/apache/tvm/issues/7734
I would like to report a problem with the JS runtime. Currently when being run the instantiation of tvm run smoothly, not resulting in any error:
```
try {
this.tvm = await tvmjs.instantiate(
wasmSource,
new EmccWASI()
);
} catch(e){
console.log(e);
}
```
However, after invoking this line (just like proposed in the https://github.com/apache/tvm/blob/main/web/tests/node/test_module_load.js):
```
this.sysLib = this.tvm.systemLib();
```
The application ended up with the following error:
```
tvmjs_runtime.wasi.js:formatted:410 Uncaught (in promise) RuntimeError: abort([object Object]). Build with -s ASSERTIONS=1 for more info.

```
Furthermore, I have been able to investigate it a little bit more and the issue most probably lies in here:

Thanks @majercakdavid Please make sure that wasm_runtime tvmjs_support are linked in your wasm. It is interesting that the partcular function is not registered, as it is done in https://github.com/apache/tvm/blob/main/src/runtime/system_library.cc#L71
as part of here https://github.com/apache/tvm/blob/main/web/emcc/wasm_runtime.cc#L53
I checked with the nodejs testcase and it seems to run fine(and the function is available). If you can try to confirm in a node env we can look further.
The community uses https://discuss.tvm.apache.org/ for general trouble shooting, we can followup there.
