Question

每当我尝试使用mysql连接构建c ++程序时，我都会收到以下错误

g++ -o dist/Debug/GNU-Linux-x86/mysqltest build/Debug/GNU-Linux-x86/main.o
    -L/usr/local/lib/lib -L/usr/lib -lmysqlclient_r -lmysqlcppconn

经过广泛搜索，我发现libstdc ++ 6和g ++ 4.4.5编译器之间存在一些问题

任何人都可以告诉我们如何解决这个问题

Answer 1

似乎GLIBCPP_3.2指的是libstdc ++ 5，而不是libstdc ++ 6.

显然，MySQL lib是使用早期版本的编译器编译的。也许你可以找到更新版本？
