I compiled php cpp extensions. I apply it to PocketMine Binary, but it doesn't load. I can get following error. PHP Warning: PHP Startup: Unable to load dynamic library 'test' (tried: /root/php/bin/php7/lib/php/extensions/no-debug-zts-20180731/test (/root/php/bin/php7/lib/php/extensions/no-debug-zts-20180731/test: cannot open shared object file: No such file or directory), /root/php/bin/php7/lib/php/extensions/no-debug-zts-20180731/test.so (/usr/lib/libphpcpp.so.2.2: undefined symbol: core_globals)) in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library 'test' (tried: /root/php/bin/php7/lib/php/extensions/no-debug-zts-20180731/test (/root/php/bin/php7/lib/php/extensions/no-debug-zts-20180731/test: cannot open shared object file: No such file or directory), /root/php/bin/php7/lib/php/extensions/no-debug-zts-20180731/test.so (/usr/lib/libphpcpp.so.2.2: undefined symbol: core_globals)) in Unknown on line 0 PocketMine PHP ver: PHP 7.3.5 (cli) (built: May 12 2019 00:55:33) ( ZTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.5, Copyright (c) 1998-2018 Zend Technologies Local PHP ver: PHP 7.3.5-1+ubuntu18.04.1+deb.sury.org+1 (cli) (built: May 3 2019 10:00:24) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.5, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.3.5-1+ubuntu18.04.1+deb.sury.org+1, Copyright (c) 1999-2018, by Zend Technologies
