Question

我尝试使用MySQL ODBC驱动程序，但在编译时导致错误。 MySQL ODBC驱动程序适用于Mariadb 5.5但不适用于Mariadb 10.那么Mariadb 10是否有ODBC驱动程序？

我安装了MySQL Connector ODBC Driver源代码版本。

以下是错误消息：

Gentoo似乎有一个补丁：

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-db/myodbc/files/5.2.7-mariadb-dynamic-array.patch?view=markup

问题是通过添加每线程内存使用情况统计信息（https://mariadb.atlassian.net/browse/MDEV-4011）引入的，这需要在my_init_dynamic_array()宏中添加一个附加参数。此宏未定义为公共客户端API的一部分，但仍在my_sys.h头文件中公开，并由MySQL ODBC使用，因此在针对最近的MariaDB版本编译时，此更改破坏了ODBC代码。

替代方案正在应用上面的补丁，或者切换到MariaDB ODBC驱动程序（虽然仍处于测试阶段）：

在Linux上是否有与Mariadb 10兼容的ODBC驱动程序？
