What does it do?

The purpose of this example is to demonstrate how to use pthread which allows the code to run multiple threads concurrently

Building instructions

Using emcc from the command line (make sure it is in your path)

mkdir build
emcc -pthread --use-port=contrib.glfw3 -sEXIT_RUNTIME=1 -sPROXY_TO_PTHREAD --shell-file=shell.html main.cpp -o build/index.html

Using CMake:

set(target "example-pthread")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -pthread --use-port=contrib.glfw3 -sEXIT_RUNTIME=1 -sPROXY_TO_PTHREAD --shell-file ${CMAKE_CURRENT_LIST_DIR}/shell.html")
add_executable(${target} main.cpp)
target_compile_options(${target} PUBLIC "-pthread")
set_target_properties(${target} PROPERTIES OUTPUT_NAME "index")
set_target_properties(${target} PROPERTIES SUFFIX ".html")

Running instructions

Note

Due to the limitations with browsers, this test needs to be run with emrun which automatically takes care of the right headers.

emrun --browser firefox build/main.html
