#30057 [Fbk->Opn]: IPv6 support broken

On FreeBSD it works, but will it break on some other OS(s)? ------------------------------------------------------------------------ [2004-09-12 11:27:24] wez@php.net <sys/sockets.h> or <sys/socket.h> ? (I'd expect the latter to be correct) It sounds like we need to add that header to our configure check to make it work (and also make IPV6 depend on its presence) ------------------------------------------------------------------------ [2004-09-12 09:10:59] neon at neon-line dot net wez: I had to add stdlib.h and sys/sockets.h headers to compile it because NULL is defined in stdlib.h (weird) and constant AF_INET in sys/socket.h. After those modifications output was "OK!" (as expected). ------------------------------------------------------------------------ [2004-09-12 02:12:23] pollita@php.net I recall the bug that prompted the extended check for ai_family and sa_family (though not the bug# off hand). It was also in BSD (I want to say it was also FreeBSD4). Enabling getaddrinfo when this behavior was present caused intermittent segfaults in the reporters build, I'll track down that original bug report, it had some detailed comments. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
