PHP 启动：无法加载动态库“phalcon.so”

Question

I am trying to run phalcon in php but it seems from the errors that it cannot load it.

PHP Warning: PHP Startup: Unable to load dynamic library 'phalcon.so' (tried: /usr/lib64/php/modules/phalcon.so (/usr/lib64/php/modules/phalcon.so: undefined symbol: __builtin_saddl_overflow), /usr/lib64/php/modules/phalcon.so.so (/usr/lib64/php/modules/phalcon.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I've tried all the solutions that are on the web but I cant solve it. I already add the extension=phalcon.so in php.ini and also made a file zzzzz.ini which contains the same extension but it does not work.

Those are the solutions that I found on the web.

Can someone else help me to solve my problem ?

Thanks in advance

I had the same problem, i resolved by upgrading GCC to >= 5.0 then recompiled Phalcon. For centOS 7

sudo yum install -y yum-utils centos-release-scl;
sudo yum -y --enablerepo=centos-sclo-rh-testing install devtoolset-7-gcc;
echo "source /opt/rh/devtoolset-7/enable" | sudo tee -a /etc/profile;
source /opt/rh/devtoolset-7/enable;
gcc --version;
