在 C++ 中将 ROCKSDB 引擎与 MariaDB 10.5.9 一起使用时出错

如何解决在 C++ 中将 ROCKSDB 引擎与 MariaDB 10.5.9 一起使用时出错

我试图在 C++ 程序中的 MariaDB 10.5.9 中使用 RocksDB 作为我的存储引擎，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并添加 plugin_add_load = 'ha_rocksdb.so' 并收到以下输出：

[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_DDL' 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 是在 /path/to/mariadb/include/my_stacktrace.h 中定义的，它包含在 /path/to/mariadb/storage/rocksdb/ha_rocksdb.cc 中，所以我不确定为什么它在加载库时出现问题。此外，当我尝试直接链接到 ha_rocksdb.so 库时，出现以下错误：

/path/to/bin/ld: cannot find -lha_rocksdb
collect2: error: ld returned 1 exit status

有什么想法吗？我使用的是 RHEL7 和 PowerPC 架构。
