Compiling GCDAsyncSocket for OS X 10.6

Question

I have troubles with compiling this wonderful TCP library with SDK 10.6.

I get:

/Users/cisary/Desktop/AI/AI/TCP/GCDAsyncSocket.m:185:11: error: instance variables may not be placed in class extension
        uint32_t flags;
                 ^
/Users/cisary/Desktop/AI/AI/TCP/GCDAsyncSocket.m:186:11: error: instance variables may not be placed in class extension
        uint16_t config;

What does instance variables may not be placed in class extension mean?

Answer 1

Are you attempting to compile for i386? That will not work with GCDAsyncSocket.m as I'm finding it on github. Instance variables defined in class extensions are a modern runtime feature. Try compiling for x86_64.
