undefined symbol: amqp_ssl_socket_set_verify_peer in Unknown on line 0

Just updated PHP to 5.6.30 and every PHP request produces a WARNING

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/amqp.so' - /usr/lib64/php/modules/amqp.so: undefined symbol: amqp_ssl_socket_set_verify_peer in Unknown on line 0

Package php-pecl-amqp-1.8.0-1.el6.remi.5.6.x86_64 is installed and the latest version.

I use CentOS release 6.7 (Final)

Solution

  • I can only reproduce with librabbitmq-last version 0.7.1

    # yum --enablerepo=remi-php56 install php-pecl-amqp
...
Installed:
  php-pecl-amqp.x86_64 0:1.8.0-1.el6.remi.5.6                                                                                                                                       

Dependency Installed:
  librabbitmq-last.x86_64 0:0.8.0-1.el6.remi

    So ensure you have latest librabbitmq-last version 0.8.0 (in "remi-safe" repository, which is required and enabled by default)

    P.S. indeed, this symbol was not in 0.7.x, but was introduced in 0.8.0
