(Which was purely coincidentally checked in on the same day this item was raised!) </p> <p> However, the intention was that _XOPEN_SOURCE should be defined when building on Solaris. In that case, iov_base is void* as per POSIX specification and older versions of boost.asio work just fine. </p> Ticket
