qt5应用odbc 使用mysql 要点
apt-get install mysql-server
apt-get install mysqlclient-dev
配置mysql-server
可以安装 apt-get install mysql-workbench
apt-get install mysql -connector-odbc
配置/etc/odbc.ini /etc/odbcinst.ini
apt-get install unixodbc
isql DNS -v 测试是否成功
不成功，检查ldd libmyodbc8w.so libmysqlclient.so是否有缺失的引用so库,缺啥补啥。
ldd libmyodbc8w.so
ldd libmyodbc8w.so

获取qt5base-everywhere-opensource源码包，tar 解开
./confiure
用qmake创建Makefile,
odbc/ qmake -o Makefile
odbc/ make 编译
检查上级目录plugins生成libqsqlodbc.so
make install //! cp mv /usr/lib不能注册 ldd检查没有缺少so,就是报driver not found错误
qdb= QSqlDatabase::addDatabase("QODBC");
//qdb =QSqlDatabase::addDatabase("QMYSQL");
qdb.setDatabaseName("mysql_dbox");//DNS name
配置成功.
