I am trying to run simple demo of phpcpp ( as given in this repository). It's working fine in ubuntu 18 but not working in cent os 7.

System version: cent os 7
PHP version:PHP 7.2

Almost the same thing with https://github.com/lpflpf/rocketmq-client-php

PHP Warning:  PHP Startup: Unable to load dynamic library 'rocketmq' (tried: /usr/local/lib/php/pecl/20190902/rocketmq (dlopen(/usr/local/lib/php/pecl/20190902/rocketmq, 9): image not found), /usr/local/lib/php/pecl/20190902/rocketmq.so (dlopen(/usr/local/lib/php/pecl/20190902/rocketmq.so, 9): Symbol not found: __ZN12PullConsumer12getGroupNameEv

After reinstalling

1. php
2. php-devel
3. php-cpp

on cent-os 7 the issue is solved in my project.

The multiple php version on system or different php-devel version can cause this issue.
