**** Build Finished ****
///////////////////////////////////////////////////////////////////////////////////////////////////////////
在/usr/include/mysql 和 /usr/lib/mysql目录下都 有头文件和库文件
查资料是连接错误，但是不知道怎么解决，请教大家。

另外，我用 $ g++ Main_1.cpp -o Main_1 -lmysqlclient 编译
/usr/bin/ld: cannot find -lmysqlclient
collect2: ld 返回 1

有哪位大侠，知道怎么解决，请赐教。谢谢！

g++ -o Main_1 Main_1.cpp -lmysqlclient -L/usr/lib/mysql

[帅得不敢出门]

g++ -L/usr/lib/mysql -o "Exmp_mysql_1" ./Res/Main_1.o
明显是少加了个库了 -lxxlib 这个xxlib中提供了mysql_init 等函数

[wenkai168]

库连接错了，mysqlclient不是库，你应该连接mysql

我也有这个问题，改怎么改？
