<pre>The symbol is defined in libc++, which is not linked together. Wasm libraries
don't exist by default as shared object files in normal Linux systems. To use
libraries, you can build libraries manually and link, or you can use tools like
Emscripten (<a href="https://emscripten.org/">https://emscripten.org/</a>).
FYI, wasm native exception handling
(<a href="https://github.com/WebAssembly/exception-handling">https://github.com/WebAssembly/exception-handling</a>) is still in progress and
not all VMs support it. But Emscripten support exception handling using
JavaScript emulation. If you use Emscripten, refer to this page
(<a href="https://emscripten.org/docs/optimizing/Optimizing-Code.html#c-exceptions">https://emscripten.org/docs/optimizing/Optimizing-Code.html#c-exceptions</a>) for
more info.</pre>
