I\'m trying to recreate a modernized version of this tutorial here - but I\'m having problems building and referencing a SWC file for inclusion in my Flash Builder project.
To build a SWC file you need to create a Library Project. You can find detailed instructions in the "About library projects" article in the Flash Builder documentation.
To use a SWC file in a Flex Project, just copy it into the libs folder of that project.
