• First run configure and make natively/normally. You will need some of the generated executables. Optionally, also build test.c and see that it works (see instructions inside test.c).

• Run configure using something like

    EMCONFIGURE_JS=1 emconfigure ./configure ABI=longlong --build=none --host=none
  

• Edit config.h and disable HAVE_QUAD_T, HAVE_OBSTACK_VPRINTF

• Run make using something like

    make -j 2
  

• Run emscripten.sh which will build the main test file, link it, then compile to JavaScript using Emscripten

• Run the code using something like

    node complete.js 500
