This is a fairly minimal example to reproduce an issue involving a pthread-enabled Emscripten build not reusing detached pthreads. There are two buttons added to the Emscripten-generated HTML, "Exec 1 pthread" & "Exec 8 pthreads". The project builds specifying a pool of 4 pthreads at startup. You can hit the "Exec 1 pthread" button all day with no issue. However, hitting the Exec 8 pthreads" button causes it to complain of an exhausted thread pool and it spins up 4 additional pthreads.
When this issue is addressed, whether it's an issue in the emsdk or just lack of understanding, this will be updated with that info.
This project comes with a basic makefile for compiling the C++ to WASM. Typing make help will give a usage message.
You can set up to build in one of several ways. One easy way is to use a Docker image. The emsdk version must be at least 3.1.64.
Once you have an emsdk set up to build:
emmake make
Then to set up the project to run:
npm install
Just run:
node express.mjs
Bring up your browser to localhost:8088/
It will redirect to bin_pt/dbg/my.html.
