It also provides you a way to run the compiled ruby interpreter on a bigger host machine using QEMU. This is essential because I rely on rubygems, and the Chumby is too small to execute the gem install commands. Besides, at least for the sqlite3-ruby and mongrel gems, I need to compile native code. | ||
