Compiling

This steps are only needed in case you want to recompile bliplay.wasm.

0. Setup emscripten

Install the emscripten enviroment (e.g. with brew):

$ brew install emscripten binaryen

Run the compiler command once to create the config file in ~/.emscripten:

$ emcc

Edit ~/.emscripten and make sure LLVM_ROOT points to the LLVM binaries inside the emscripten directory /usr/local/Cellar/emscripten/1.37.25/libexec/llvm/bin and BINARYEN_ROOT points to /usr/local/Cellar/binaryen/89 (versions may change):

...
# this helps projects using emscripten find it
EMSCRIPTEN_ROOT = os.path.expanduser(os.getenv('EMSCRIPTEN', '/usr/local/Cellar/emscripten/1.37.25/libexec')) # directory
LLVM_ROOT = '/usr/local/Cellar/emscripten/1.38.11/libexec/llvm/bin'
BINARYEN_ROOT = os.path.expanduser(os.getenv('BINARYEN', '/usr/local/Cellar/binaryen/89')) # if not set, we will use it from ports
...

1. Checkout

Checkout the submodules:

git submodule update --init --recursive

2. Build

Build bliplay.js and bliplay.wasm:

$ make

Running

You can now run index.html on a webserver. Opening it directly from the file system may not work. Or by running the following, which will start a nginx container:

make server-start
