Hi,
You can build native Pepper plugins w/out building Chrome; we do this in the
NaCl SDK. You'll just need to be able to build a native shared object for your platform.
It is mostly only useful for debugging -- so you can use the platform's native debugger, for example. You cannot easily distribute a native Pepper plugin, and the only way to load it is to pass commandline flags to Chrome. Also, the plugin will be OS- and architecture-specific.
Building a
PNaCl plugin is nicer in this regard. You can build it once, and run it on Chrome for Windows, Mac, Linux and Chromebooks. It also can be distributed on the open web, and will load without any additional flags.
