Uncaught surprising proxied syscall: 202

[Hao-Yan]

I am porting some cross platform code to WebAssembly, now it build successfully, when run, I met below issue. Did anyone have some insight on this?

I checked the code where the exception throw, seems 202 syscall is not implemented in _emscripten_syscall. My emscripten version is 1.38.21. BTW, I use -s WASM=0 when compile. I also use embind when call from js to c++.

Hmm, that function is autogenerated based on the syscalls seen at compile time. Is it possible you're calling the syscall in a nonstandard/dynamic way? Do you have a testcase showing the issue?

Testing locally, if I statically call getgid()/getegid() manually I do see it get proper proxying code.

@kripken , you are right. There is some code related to SQLite which used some dynamic way to do syscall.

To let the __emscripten_syscall generate the 202 syscall, I just manually call getgid()/getegid() in another source file. Thanks for the help.
