报错：PHP Warning: PHP Startup: Unable to load dynamic library 'swoole.so' (tried: /usr/lib/php/20180731/swoole.so (/usr/lib/php/20180731/swoole.so: undefined symbol: _zval_ptr_dtor), /usr/lib/php/20180731/swoole.so.so (/usr/lib/php/20180731/swoole.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
php版本7.3,pecl和wget两种安装方式都是试过了不行。哪位大神能帮忙解决下，小弟不胜感谢
首先 访问swoole官网 : 点击打开链接 下载源码包 我通过的git下载
进入swoole 目录 通过phpize(注:使用phpize命令 必须开启php-dev扩展 ) 命令 扩展php模板 ,生成./configure文件
使用 ./configure 命令 作用 :一.对即将安装的软件进行配置 二. 检测当前环境是否满足软件安装的依赖关系
4. 使用make 及 sudo make install
5.安装成功 使用 ln -s 软连接 开启php-swoole扩展 例如: sudo ln -s /etc/php/7.2/mods-available/swoole.ini /etc/php/7.2/cli/conf.d/20-swoole.ini (注: 没有swoole.ini 需要自行创建swoole.ini文件)

改成root@shen-Lenovo-XiaoXin-700-15ISK:~/swoole-src# ./configure --with-php-config=/usr/local/php/bin/php-config后执行成功
make && make install 命令也能执行成功
软链接也添加了，执行php 7.3 -m还是看不到swoole扩展
