Emscripten dylink and pthread demo

This demo shows how to build a dynamic library with pthread support in Emscripten.

First, googletest is built as a dynamic library with pthread support.

Then an example test that dynamically links to googletest is also built as a dynamic library with pthread support. Although it is built as dynamic library this module contains the main entry point.

Finally, an empty file is built as Emscripten's main module, which hosts the system libraries. This main module dynamically links to the example test library.

Build

Run the following commands to build the demo and launch a local web server.

$ docker build -t emscripten-dylink .
$ docker run --rm -it --net=host -v "$(pwd)":"/app/" emscripten-dylink

Once the build has finished visit http://localhost:5000/main.html to see the test running in your browser. You should see the following output (up to timing differences):
