`undefined symbol: zend_class_serialize_deny` when starting

[Draghmar]

Updated to 8.1.2 on my server and got

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

When trying to do anything related to php-swoole (even php --ri swoole does that) , which is in the newest version. Not sure what's going on. It should be compatible with 8.1, right? I tried even to build Swoole again, just to be sure everything was ok with the library.

zend_class_serialize_deny function has been removed from PHP-8.1.*. Try executing make clean directive and rebuilding swoole.

[Draghmar]

I downloaded master with git, did phpize, ./configure, make clean, make, make install. Didn't help.

[Draghmar]

I also tried phpize clean but that also didn't help. I tried to build it on different machine, where swoole wasn't installed before and there was already PHP 8.1. And the result is still the same. There's really something wrong. Two machines I tried to build on, are ArchLinux based. Original machine:

Sorry, I can not reproduce it. There's nothing wrong with my server.

Could you please show me the log when executing make directive? Thanks.

Here's the log when trying to build 5.0.0-dev. Funny enough, I can't even do make test because it skips all the tests because the "missing swoole.so" ;) swoole_make.log

[NathanFreeman]

Could you please show me the log when executing phpize and configure directive? Thanks.

[Draghmar]

Here you go: swoole_configure.log swoole_phpize.log

If you make sure that you are using PHP-8.1.x, then when you execute phpize, you should have seen PHP Api Version: 20210902, but now it's 20200930 instead (which is PHP-8.0.x's API no). So, I guess that your system's local env has fallen into chaos. Maybe you need to re-install PHP and configure the system env correctly, after that, you can try to re-install Swoole again.

[Draghmar]

OMG, you were right! I don't know why, but current files are in /usr/include/php and phpize is looking in /usr/local/include/ where older files were. I didn't change anything and PHP was updated during standard system update so something must have go wrong at that level. Anyway - thanks!

@veleg Please, note your error is slightly different now. Before it was:

undefined symbol: zend_class_serialize_deny

Now it is:

undefined symbol: curl_ce
undefined symbol: socket_ce

To solve this, make sure that you extension=swoole is before curl and sockets extensions. Try to move extension=swoole to the last line of your php.ini or add a custom swoole.ini at PHP's /conf.d directory.

What Veleg is showing - is 2 different path references one is 20190902 and another 20210902.

Your logs say: (tried: /usr/lib/php/20190902/openswoole.so

And the /usr/lib/php/20210902

Something wrong with logs or installation.
