错误：

#warning This file should not be included by clients, include only <mysql.h> ^ In file included from _mysql.c:46:0: /usr/include/mysql/mysql.h:440:3: warning: function declaration isn’t a prototype [-Wstrict-prototypes] MYSQL_CLIENT_PLUGIN_HEADER ^ _mysql.c: In function ‘_mysql_ConnectionObject_ping’: _mysql.c:2005:41: error: ‘MYSQL’ has no member named ‘reconnect’ if ( reconnect != -1 ) self->connection.reconnect = reconnect; ^ error: command 'gcc' failed with exit status 1

错误原因是 MariaDB 10.2 、10.3 的 MySQL 版本时没有 reconnect

解决：

vim /usr/include/mysql/mysql.h​

搜索 st_mysql 定义结构，添加 reconnect 声明如下：

unsigned int reconnect; /* matt hacking mysql by mimvp.com */

或

my_bool reconnect; /* set to 1 if automatic reconnect by mimvp.com */
