memdup() returns a pointer of the type void*, that is a pointer of
unspecified type. eai2->ai_addr is a pointer to struct sockaddr_storage. The
C++ compiler assumes that both pointers are incompatible and generates an
error.

You simply need a cast and it will work:
eai2->ai_addr = (struct
sockaddr_storage*)memdup(&localAddressArray[i],sizeof(struct
sockaddr_storage));

This cast should also have been in examplepe.c. It will be there in the next
version.
