Hello : Can angelscript run on arm platform, eg. arm7, arm9 .etc ??? Can angelscript run on arm platform without OS, or run on a naked machine ?? thanks.

Yes, AngelScript can be used on ARM platforms. As long as you have a C++ compiler for the platform.

AngelScript is just a scripting library, it needs to be embedded in an application that provides the functionality. AngelScript don't access any outside resources except via the application, so yes, you can use AngelScript on a platform that doesn't have any OS.
