Anyway, it's worth noting that when I was finally able to build, I did so after following those instructions, so I'm not sure at this time whether or not they were necessary.

I changed the SDK to 4.2 using the project inspector. Worked too.

But I had a problem in SocketPlugin/sqUnixSocket.c that netinet/udp.h was not found. Anyone else seeing this? I removed the #include and it seemed to work ...

Maybe because I set the minimal deployment version to 3.2? I didn't experiment much.
