Problems with callbacks using emscripten with pthreads

Question

emscripten_set_click_callback does not work with multithreading.

I'm not sure why, but certain functions like emscripten_set_click_callback and other similar input functions don't work with pthreads enabled, it gives an error saying it cannot target thread for callback. I need to enable input to have audio in the browser work and there's nothing I can find in the docs about this issue or how to fix it.

What do you mean by *"don't work"*? which is the return value of `EMSCRIPTEN_RESULT`? — Jarod42, Aug 18 '23 at 22:52

So it turns out I'm not crazy, and it indeed was a bug. The solution was to run emsdk install tot and it now works. Must have been a newer update, which is strange considering I had just updated emscripten about a week ago.
