EmCPython

A working Emscripten port of CPython.

Build

• Install Emscripten SDK, make sure emcc, emmake, and setup environment variables.

• Clone EmCPython repository with submodules: git clone --recursive https://github.com/PeachPy/EmCPython.git

• Switch to EmCPython directory: cd EmCPython.

• Run ./build-python.sh. It will cross-compile CPython 2.7 and install it into EmCPython/emscripten.

• Run ./build-libtar.sh. It will cross-compile libtar and install it into EmCPython/emscripten.

• Run ./pack-modules.py -p emscripten -o pydata.tar. It will create a TAR with Python modules from EmCPython/emscripten/lib/python2.7/.

• Switch to EmCPython/test directory: cd test.

• Run ninja to build the test. It will create python.asm.js and python.asm.js.mem files.

• Execute python.asm.js with Node.js: node python.asm.js
