(I didn't test with this, just judge by the reporting) Previous Comments: ------------------------------------------------------------------------ [2012-09-03 02:53:16] reeze dot xia at gmail dot com I haven't use this option before, if it's an important feature, if your patch didn't apply the only impact is the warning issued ? that maybe need to be fixed, but if not... eg this bug https://bugs.php.net/bug.php?id=62881 I reported. maybe the bug reported may set to won't fix :( more conversation see: https://github.com/php/php-src/pull/176 anyway I prefer it get fixed :) ------------------------------------------------------------------------ [2012-09-03 02:47:47] reeze dot xia at gmail dot com Ah, you mention which version the bug exist, both 10.7&10.8 right ? Is there any way to detect whether is broken or not disable it seems not a better choice. ------------------------------------------------------------------------ [2012-09-02 21:41:13] igor at wiedler dot ch See also: http://trac.videolan.org/vlc/ticket/6104#comment:19 ------------------------------------------------------------------------ [2012-09-02 21:38:36] igor at wiedler dot ch Description: ------------ The multicast support in PHP 5.4 makes use of MCAST_JOIN_GROUP if it is present. The problem is that OSX 10.7 added the constant, but did not correctly implement the feature. This causes the setsockopt call to fail. The solution to the problem is to not use MCAST_JOIN_GROUP on OSX. Test script: --------------- <?php if (!extension_loaded('sockets')) { die('skip sockets extension not available.'); } if (PHP_OS !== 'Darwin') { die('is not OSX.'); } $socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP); socket_bind($socket, '0.0.0.0', 31057); $so = socket_set_option($socket, IPPROTO_IP, MCAST_JOIN_GROUP, array( "group" => '224.0.0.251', "interface" => 0, )); var_dump($so); Expected result: ---------------- bool(true) Actual result: -------------- PHP Warning: socket_set_option(): unable to set socket option [22]: Invalid argument in /Users/igor/code/react-mdns-userland/src/React/Mdns/Client.php on line 27 PHP Stack trace: PHP 1. {main}() /Users/igor/code/react-mdns-userland/examples/client.php:0 PHP 2.
