Emscripten CPP Examples

Examples showing how you can use C++, CMake and Emscripten to make both web and native applications.

Dependencies

• CMake
• Emscripten SDK (emsdk)

Building/Compiling

The following build instructions are tailored towards Linux systems.

Note: Make sure you have installed the Emscripten SDK and you have your terminal environment setup for using the SDK commands.

# Create build scripts with CMake
emcmake cmake .

# Compile the code to Web Assembly (WASM)
emmake make

All the WASM binaries should be located in the bin folder. Now to run these WASM binaries, you will need to host the HTML files on a development server and contact the server through your web browser. I recommend using the Live Server plugin for VSCode, although anything that can host your HTML should work.
