Maybe you’ve been using codebender for a while and have had great success making things. You write the code, click the magic ‘Run on arduino’ button and a few seconds (and some blinking LEDs) later your board is programmed and you enjoy the fruits of your efforts. If you have ever wondered how that generated machine code gets its way into your board, this article is for you.
Ever since codebender started growing, one of the biggest challenges we faced was pushing updates to our compiler and being able to quickly iterate on it, fixing bugs and improving its performance. Since we’re kind of obsessed with making all of codebender’s users happy, we need to make sure that all changes applied to the compiler won’t break existing sketches. After all, what’s a web Arduino IDE if you can’t compile your code in it? As of today, about 70000 users have registered to codebender and it hosts more than 200000 projects. How can you make sure all of them work fine without having the whole testing process last forever?
In our blogpost today we will show you how you can create a simple installer application with the help of PackageMaker. The installer will install a kernel extension file to a Mac OS X with a version greater than or equal to 10.9.
