a native client game prototype
Exploring native client with a 2D context.
To build, there are two lines at the top of the Makefile that need to be changed. That should be it.
NACLPORTS_ROOT = /home/derek/dev/naclports/src NACL_SDK_ROOT = ~/dev/nacl_sdk
where ~dev/nacl_sdk a symlink to native_client_sdk_0_1_507_0/
That SDK is pretty old, so the project includes some recent source from SVN to enable key events.
$ make $ python httpd.py $ chrome --enable-nacl
httpd.py will emit an address like localhost:5103 click the pepper_plugin.html
