Hello, First, I'm not a developer. But am smart enough to follow directions. I'm trying to compile and build a piece of open source software from github. When I try this I get the errors in the attached screenshot. When I called apple they said Id have to pay for a developer account if I wanted the software to work beyond a pre-determined testing period. Is this true? I'm not trying to create an app for the appstore or distribute this in any way. Just need this key piece of software in my music setup. I appreciate any help.
