Qsqldatabase: qmysql driver not loaded appears when QT is connected to MySQL.

Qsqldatabase: qmysql driver not loaded

Qsqldatabase: available drivers: qsqlite

Solution: Check whether libqsqlmysql. So has been installed.

[Test1 @ localhost ~] $ Locate libqsqlmysql. So

/Var/Cache/abrt-DI/usr/lib/debug/usr/lib/qt4/plugins/sqldrivers/libqsqlmysql. So. Debug

I have not installed it on my system. Install the qt-mysql.i686 below.

[Root @ localhost test1] # Yum install qt-mysql.i686

Installing:

Qt-MySQL i686. 7.4-7. fc14 updates 67 K

[Root @ localhost test1] # updatedb

[Test1 @ localhost ~] $ Locate libqsqlmysql. So

/Usr/lib/qt4/plugins/sqldrivers/libqsqlmysql. So

/Var/Cache/abrt-DI/usr/lib/debug/usr/lib/qt4/plugins/sqldrivers/libqsqlmysql. So. Debug

Call in the program

Qdebug () <qcoreapplication: librarypaths ();

You can see the path of the QT Search Library. No/usr/lib/qt4/plugins/

There are two ways to solve this problem:

1. Add the path of libqsqlmysql. So to the library path:

Qcoreapplication: addlibrarypath ("/usr/lib/qt4/plugins /");

2. Directly copy libqsqlmysql. So to the search path of QT.

[Test1 @ localhost ~] $ CP/usr/lib/qt4/plugins/sqldrivers/libqsqlmysql. So qtsdk/desktop/QT/4.8.1/GCC/plugins/sqldrivers/
