How to do multi-threading with emscripten?

[aarlt]

I just leave a question here, so maybe somebody knows the answer and can give me some feedback 😅

How can I enable multi-threading in emscripten? I did some superficial research on that, but I was not successful. So far I did not had the time to dig deeper in that.

However, I tried already different things described here:

• linking with pthread (that is already done in this example)
• defining a thread pool-size with -sPTHREAD_POOL_SIZE
• compiling with -sPROXY_TO_PTHREAD

But in all cases the application get terminated with an exception while starting the thread. My understanding is that emscripten is now supporting posix threads, because there is now shared memory support in browsers. This example tries to start a thread when a button is pressed. The button is located inside the "Hello, world!" window, where a click on the button "Button" tries to create a new thread.

I mean for simple applications that is probably sufficient, but to have real threading support here would be really just awesome. However, I was not able to make this work. Any help will be very appreciated 😄
