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 () <

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/
