我试图在 C++ 程序中使用 RocksDB 作为 MariaDB 10.5.9 中的存储引擎，但遇到以下错误：
Got ERROR: "unknown: Can't open shared library '/path/to/mariadb/install/lib/plugin/ha_rocksdb.so' (errno: 0, undefined symbol: my_safe_printf_stderr)" errno: 2000

我已经确认 RocksDB 是使用 mysql 安装的：
+--------------------+---------+-----------------------------------------------------------+
| Engine | Support | Comment | Transactions | XA | Savepoints |
+--------------------+---------+-----------------------------------------------------------+
| ROCKSDB | YES | RocksDB storage engine | YES | YES | YES |
我进一步确认插件已安装，添加plugin_add_load = 'ha_rocksdb.so'并接收以下输出：
[ERROR] mysqld: Plugin 'ROCKSDB' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_CFSTATS' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_DBSTATS' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_PERF_CONTEXT' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_PERF_CONTEXT_GLOBAL' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_CF_OPTIONS' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_COMPACTION_STATS' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_GLOBAL_INFO' already installed

[ERROR] mysqld: Plugin 'ROCKSDB_INDEX_FILE_MAP' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_LOCKS' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_TRX' already installed
[ERROR] mysqld: Plugin 'ROCKSDB_DEADLOCK' already installed
我还看到 my_safe_printf_stderr 定义在 中/path/to/mariadb/include/my_stacktrace.h，它包含在 中/path/to/mariadb/storage/rocksdb/ha_rocksdb.cc，所以我不确定为什么它在加载库时遇到问题。此外，当我尝试直接链接到 ha_rocksdb.so 库时，我收到以下错误：
/path/to/bin/ld: cannot find -lha_rocksdb
collect2: error: ld returned 1 exit status
有任何想法吗？我在 RHEL7 和 PowerPC 架构上。
