I have bought a new Mac Pro and installed Xcode 7.3.1 and MaxSDK-7.1. I wanted to test if it worked and opened the „plussz“ example project. When I pressen the „Build“ menu item, I received the message „Build succeeded“. But when I tried to open this external in Max, I received the message: plussz: unable to load extern, object has no ‚main’ function. What??? How can this be? It is there, in the file plussz.c. Can anybody explain thsi and tell me what to do?
