Re: Zerolink and undefined symbol _main

I should point out that with zerolink on, everything
builds just fine.

While the framework does use a few .a files, there are
no other dependencies, certainly not any other xcode
projects which would be built with zerolink on.

Targets that "build fine with ZeroLink on" are building fine because there is zero linkage phase, and hence there is no check for undefined symbols. It's like saying you never find you drive too fast when the speedometer is taped-over.

Observe the symbol the linker wants: _main. That's a C function, named main. Your target seems to think it is not a framework, but an application or a tool. What's the Wrapper Extension setting say?
