Edit report at https://bugs.php.net/bug.php?id=74865&edit=1 ID: 74865 Comment by: neal at aegis dot systems Reported by: rafal dot ksiazek at workhq dot com Summary: PHP7.0-xml dom.so: undefined symbol: php_libxml_node_free_list Status: Open Type: Bug Package: DOM XML related Operating System: Ubuntu 14.04 PHP Version: 7.0.21 Block user comment: N Private report: N New Comment: I ran into this problem this morning after a yum update of php70. What I found was a hard copy of the php executable in /usr/bin/ rather than a link. That left an old version of php as the default executable for which php. So essentially, yum updated remi php but the old executable was still being called.. resulting in an error. I deleted the old/stale version /usr/bin/php and created a link to the installed remi path. #ls -altrh /usr/bin/ lrwxrwxrwx. 1 root root 36 Jul 6 09:21 php54-cgi -> /opt/remi/php54/root/usr/bin/php-cgi* lrwxrwxrwx. 1 root root 32 Jul 6 09:21 php54 -> /opt/remi/php54/root/usr/bin/php* lrwxrwxrwx. 1 root root 38 Jul 6 09:21 php54-phar -> /opt/remi/php54/root/usr/bin/phar.phar* lrwxrwxrwx. 1 root root 33 Jul 6 09:21 php54-pear -> /opt/remi/php54/root/usr/bin/pear* lrwxrwxrwx. 1 root root 32 Jul 6 09:21 php55 -> /opt/remi/php55/root/usr/bin/php* lrwxrwxrwx. 1 root root 38 Jul 6 09:21 php55-phar -> /opt/remi/php55/root/usr/bin/phar.phar* lrwxrwxrwx. 1 root root 36 Jul 6 09:21 php55-cgi -> /opt/remi/php55/root/usr/bin/php-cgi* lrwxrwxrwx. 1 root root 33 Jul 6 09:21 php55-pear -> /opt/remi/php55/root/usr/bin/pear* lrwxrwxrwx. 1 root root 38 Jul 6 09:22 php56-phar -> /opt/remi/php56/root/usr/bin/phar.phar* lrwxrwxrwx. 1 root root 36 Jul 6 09:22 php56-cgi -> /opt/remi/php56/root/usr/bin/php-cgi* lrwxrwxrwx. 1 root root 32 Jul 6 09:22 php56 -> /opt/remi/php56/root/usr/bin/php* lrwxrwxrwx. 1 root root 33 Jul 6 09:22 php56-pear -> /opt/remi/php56/root/usr/bin/pear* lrwxrwxrwx. 1 root root 32 Jul 6 09:22 php70 -> /opt/remi/php70/root/usr/bin/php* lrwxrwxrwx. 1 root root 38 Jul 6 09:22 php70-phar -> /opt/remi/php70/root/usr/bin/phar.phar* lrwxrwxrwx. 1 root root 36 Jul 6 09:22 php70-cgi -> /opt/remi/php70/root/usr/bin/php-cgi* lrwxrwxrwx. 1 root root 36 Jul 6 09:22 php71-cgi -> /opt/remi/php71/root/usr/bin/php-cgi* lrwxrwxrwx. 1 root root 32 Jul 6 09:22 php71 -> /opt/remi/php71/root/usr/bin/php* lrwxrwxrwx. 1 root root 38 Jul 6 09:22 php71-phar -> /opt/remi/php71/root/usr/bin/phar.phar* lrwxrwxrwx. 1 root root 32 Jul 6 09:27 php -> /opt/remi/php70/root/usr/bin/php* Previous Comments: ------------------------------------------------------------------------ [2017-07-06 12:41:53] spam2 at rhsoft dot net again: this is a downstream problem in the distribution or a config problem and given that in your output "Zend OPcache" appears twice and must not exist in "[PHP Modules]" i wouldn't trust you whole configuration whoever is responsible for "extension = opcache.so" which is just plain wrong don't copy&paste that below blindly because you don#t have the same build and most likely some parts not as shared extension at all the first part is from "php.ini" for httpd and responsible for the opcache loading shared between all servers and the scond part is a machine specific override, since we rely heavily on dom/xml and have a large autotest-suite for our application i can assure you ta´hat upstream PHP works exactly like before when it's proper built and configured [zend] zend_extension = "opcache.so" opcache.enable = 1 opcache.enable_cli = 0 opcache.load_comments = 0 opcache.save_comments = 0 opcache.use_cwd = 1 opcache.validate_timestamps = 1 opcache.validate_permission = 0 opcache.revalidate_freq = 15 opcache.revalidate_path = 0 opcache.max_accelerated_files = 1000 opcache.memory_consumption = 32 opcache.interned_strings_buffer = 8 opcache.preferred_memory_model = "mmap" opcache.max_file_size = 327680 opcache.enable_file_override = 1 opcache.fast_shutdown = 1 opcache.log_verbosity_level = 2 opcache.huge_code_pages = 1 cat /etc/php.lounge.d/extensions.ini extension = "zlib.so" extension = "openssl.so" extension = "mbstring.so" extension = "apcu.so" extension = "bz2.so" extension = "calendar.so" extension = "ctype.so" extension = "curl.so" extension = "dom.so" extension = "exif.so" extension = "fileinfo.so" extension = "gd.so" extension = "geoip.so" extension = "hash.so" extension = "iconv.so" extension = "imagick.so" extension = "imap.so" extension = "intl.so" extension = "json.so" extension = "mysqlnd.so" extension = "mysqli.so" extension = "pdo.so" extension = "pdo_mysql.so" extension = "session.so" extension = "simplexml.so" extension = "soap.so" extension = "tidy.so" extension = "xml.so" extension = "zip.so" opcache.memory_consumption = 256 opcache.max_accelerated_files = 10000 opcache.interned_strings_buffer = 8 ------------------------------------------------------------------------ [2017-07-06 12:38:15] rafal dot ksiazek at workhq dot com Hmm.. ok, when I purged whole php7.0-* and installed it again, everything is working fine.
