Cpp2js

Cmake project to demonstrate the compilation of C++ sources to Webassembly + js

Required tools

• Cmake: Simply download and install following the instructions here
• Emscripten SDK: just

git clone [email protected]:emscripten-core/emsdk.git
cd emsdk
./emsdk install latest

Building the example

• locate the Emscripten.cmake in your emsdk source folder (should be /path/to/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake)
• create a build folder and cd into it

cd /path/to/cpp2js
mkdir build
cd build

Compile to webassembly and js

Notice: the build will not export the main

• build with

cmake -DCMAKE_TOOLCHAIN_FILE=<path_to>/Emscripten.cmake -DCMAKE_BUILD_TYPE=Release
cmake --build -- -j8

• serve /path/to/cpp2js with your favorite web server

Native compilation (for debugging)

Notice: a main function is provided for ease of testing and debugging. A suitable cpp compiler (gcc, clang) is required

cmake -DCMAKE_BUILD_TYPE=Debug
cmake --build -- -j8
