Install mysql driver for qt in ubuntu

[DenisKormalev]

Yes we've installed only driver for qt. If you want to store databases at your computer you need to install both mysql-server and mysql-client. If you will connect to remote database you can install only mysql-client.

will it work if i install mysql server and client after installing mysql driver for qt? or if i install xamp then it will also work with qt. i am not using qt for web interface. i am using qt just to create desktop and mobile apps.

[DenisKormalev]

Yes it should work. For better compatibility install client with exactly same version as your installed dev packages.

[doforumda]

how would i know the version of my installed dev packages(by dev packages you mean which i installed for qt now).

and your reply "Yes it should work." means xamp will also work??

[DenisKormalev]

You SHOULD have mysql-server to be able to store and work with mysql databases at your computer.
Mysql-client is set of libraries and binaries which give access to mysql server (your or remote) for other applications or for you directly from console (mysql utility I'e mentioned before).
As I've seen earlier in thread you've installed mysql dev packages for mysql 5.0, so you need to install server and client versioned 5.0.

ok i created a db "testTwo" in xampp. that db is in opt/lampp/var/mysql/testTwo folder. Now if i want to use this db then will code in my qt will get this db automatically when i provide QSqlDatabase db->setDatabaseName("testTwo"); or i need to copy this db somewhere else to make it available for qt?

[DenisKormalev]

I've never worked with xampp, but if it has mysql server in it and this server is running then all should be ok.

[doforumda]

can you please check this thread i have some problem in loading mysql driver? "Your text to link here...":http://developer.qt.nokia.com/forums/viewthread/1208/

Yet can't install according to above.
Why I get

@***Unknown option -lmysqlclient_r”@

when running

@qmake “INCLUDEPATH+=/usr/include/mysql” “INCLUDEPATH+=/home/paul01/QtSDK/Desktop/Qt/4.8.0/gcc/include/Qt” “LIBS+=-L/usr/lib/mysql -lmysqlclient_r” mysql.pro@

and next errors after make :

Dear it is automatic giving in ubuntu...yesterday day installed it via ububtu software center and when I write the aboe code in console it gives me the followng output..
#include <QtSql>
int main(int argc,char * argv[])
{
QSqlDatabase db;
qDebug()<<db.drivers();
}
just added QT += sql in .pro file

Try OpenSUSE 11.4 and you will never find any problem ! Qt will be installed and well configured with KDE desktop :)

OpenSUSE 11.4 : http://software.opensuse.org/114/en

the sdk. It doesn't exist.[/quote]

My friend try go in Qt Tools>Options>QtVersions>In Autodetected chose you Qt compiler>Look down click on Qt version 5 Details. Now look you PLUGINS folder and go. In sqldrivers folder check file libqsqlmysql.so exist and ins not protected.
If u not have this file download form Ubuntu software center searching libqt5 for QT5 or liqt4 for QT4 and install later copy the installed file /usr/lib/x86_64-linux-gnu/qt5/plugins/sqldrivers for 64bits machine or /usr/lib/i386-linux-gnu/qt5/plugins/sqldrivers for 32bits machine. to you plugins proyect folder
Sorry for my english regars from Argentina
