QMYSQL driver available but not loaded

Question

How do I load qmysql driver in Qt? I have the following code that produces these results:

(\"QSQLITE\", \"QMYSQL\", \"QMYSQL3\") 
QSqlDatabase:          


        

Answer 1

We should check our driver first

$ cd /opt/Qt5.2.1/5.2.1/gcc_64/plugins/sqldrivers

then we can find some files

Use the command below to check library

$ ldd libqsqlmysql.so

if you find the problem libmysqlclient_r.so.16 => not found it may be the library-dependency problem.

After I did a little research on the Internet, there is a way would be easy.

$ cd /usr/lib/x86_64-linux-gnu

if you find libmysqlclient_r.so.18,

$ cp libmysqlclient_r.so.18 libmysqlclient_r.so.16
