QSqlDatabase: QMYSQL driver not loaded 解决方法

在Linux下用qt连接mysql数据库时,连接不上数据库,报QSqlDatabase: QMYSQL driver not loaded这个错误。

  1. 先检查数据库MYSQL有没有正确安装。
  2. sudo apt-get install libqt4-sql-mysq或者sudo apt-get install libqt5-sql-mysq 安装qt sql驱动
  3. 如果还不行,和可能是libmysqlclient.so的版本不对。需要下载安装libmysqlclient16。下载地址
I have had the similar problem on Kubuntu 14.04 64 bit with the latest 5.3.1 Qt relase downloaded from the qt-project and installed to the /opt. 
The Ubuntu 14.04 ships with libmysqlclient 18 while the Qt 5.3.1 is built with 16. So the creating of a symlink like above did not solved my issue. 
Finally I have downloaded the libmysqlclient 16 from here:
