我已经使用以下过程为 PHP 安装了 datastax cassandra 驱动程序扩展：
- 安装依赖：automake cmake gcc gcc-c++ git libtool openssl-devel wget gmp gmp-devel boost php-devel pcre-devel git libuv gmp
- 从源码编译安装cpp-driver
- 从源代码安装 PHP Datastax cassandra 驱动程序
- 在 /etc/php.ini 文件中添加了扩展名
当我尝试执行 php 文件以连接到 cassandra 集群时，出现以下错误：
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/cassandra.so'
- /usr/lib64/php/modules/cassandra.so: undefined symbol: cass_cluster_set_whitelist_dc_filtering in Unknown on line 0
我尝试使用二进制文件再次安装，但我仍然面临同样的问题。
这是 ldd 输出：
