Bug #64833 [NEW]: ext/sockets/sendrecvmsg.c related compilation errors

From: clicky at erebot dot net Operating system: Debian Squeeze PHP version: 5.5.0RC1 Package: Compile Failure Bug Type: Bug Bug description:ext/sockets/sendrecvmsg.c related compilation errors Description: ------------ While trying to build PHP 5.5.0RC1 under Debian Squeeze, the following compilation errors were triggered. I think this may be related to this commit that introduced support for SCM_CREDENTIALS and other goodies in the sockets extension recently: http://git.php.net/?p=php-src.git;a=commitdiff;h=a85d7f28f69fbc522ed90aee1926d3733be7620d Also, please note that the manpage for UNIX sockets states that "struct ucred" (which is used in the code) is only defined when the _GNU_SOURCE macro is defined since glibc 2.8 [1]. This may also be the reason why the build fails (Debian Squeeze uses libc6-2.13 [2]). Other projects have been impacted by this issue too [3]. [1] http://manpages.ubuntu.com/manpages/karmic/en/man7/unix.7.html [2] http://packages.debian.org/wheezy/libc6 [3] http://sourceforge.net/p/wide-dhcpv6/bugs/29/ (also contains link to a glibc commit that changed some of the structs like in6_pktinfo to be macro-guarded). Test script: --------------- './configure' \ '--enable-debug' \ '--disable-all' \ '--disable-short-tags' \ '--disable-sigchild' \ '--with-layout=GNU' \ '--with-regex' \ '--with-openssl=shared' \ '--with-zlib=shared' \ '--enable-bcmath=shared' \ '--with-bz2=shared' \ '--enable-calendar=shared' \ '--with-gettext=shared' \ '--enable-mbstring=shared' \ '--enable-pcntl=shared' \ '--enable-sockets=shared' \ '--with-pdo-sqlite' \ '--enable-sysvmsg=shared' \ '--enable-sysvsem=shared' \ '--enable-sysvshm=shared' \ '--with-xsl=shared' \ '--with-iconv=shared' \ '--enable-zip=shared' \ '--enable-posix=shared' \ '--enable-libxml=shared' \ '--enable-dom=shared' \ '--enable-xml=shared' \ '--enable-xmlreader=shared' \ '--enable-xmlwriter=shared' \ '--enable-tokenizer=shared' \ '--enable-pdo' \ '--enable-ctype=shared' \ '--enable-json=shared' \ '--enable-session=shared' \ '--enable-soap=shared' \ '--enable-simplexml=shared' \ '--enable-hash' \ '--enable-intl=shared' \ '--enable-phar=shared' \ '--with-sqlite3' \ '--with-mysql=shared,mysqlnd' \ '--with-mysqli=shared,mysqlnd' \ '--with-pdo-mysql=shared,mysqlnd' \ '--prefix=/home/qa/phpfarm/inst/php-5.5.0RC1-debug' \ '--exec-prefix=/home/qa/phpfarm/inst/php-5.5.0RC1-debug' \ '--without-pear' \ '--enable-cgi' \ '--enable-cli' \ '--enable-fpm' \ "$@" (but could probably be reduced to just ./configure --disable-all --enable-sockets=shared) Expected result: ---------------- PHP should build without any compilation error.
