QMYSQL driver not loaded on Ubuntu

[SGaist]

You have the version 18 and not the 16.

So two solutions here:

1. find the version 16
2. build the Qt MySQL plugin yourself with this version of the client library (best)

Sorry , but can you help me for find or build qt mysql plugin ?
I run this command : root@Gigabyte-Z68P-DS3:/opt/Qt5.2.0/5.2.0/Src/qtbase/src/plugins/sqldrivers/mysql# qmake "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/mysql -lmysqlclient_r" mysql.pro

I think my command is not true ! in QT 5.2 any folders and roots is different...

[SGaist]

did you call make after that ?

[A Former User]

I run first this command : root@Gigabyte-Z68P-DS3:~# cd /opt/Qt5.2.0/5.2.0/Src/qtbase/src/plugins/sqldrivers/mysql

after :

root@Gigabyte-Z68P-DS3:/opt/Qt5.2.0/5.2.0/Src/qtbase/src/plugins/sqldrivers/mysql# qmake "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/mysql -lmysqlclient_r" mysql.pro
qmake: could not find a Qt installation of ''
root@Gigabyte-Z68P-DS3:/opt/Qt5.2.0/5.2.0/Src/qtbase/src/plugins/sqldrivers/mysql#

Are you sure you are using the right qmake ?

Also, why are you developing as root ?

root@Gigabyte-Z68P-DS3:~# dpkg --get-selections | grep qmake

I don't see any Qt related dev package

[A Former User]

How can I install Qt related dev package ?

[SGaist]

IIRC you can install qt5-default then the same qt5 packages with a trailing -dev in the name

[A Former User]

See now i installed qt dev package :

Description: Qt 5 development defaults package
Qt is a cross-platform C++ application framework. Qt's primary feature is its rich set of widgets
that provide standard GUI functionality.

This package sets Qt 5 to be the default Qt version to be used when using development binaries like
qmake. It provides a default configuration for qtchooser, but does not prevent alternative Qt
installations from being used.

Ok...

Yes... please see again an error:

root@Gigabyte-Z68P-DS3:/opt/Qt5.2.0/5.2.0/Src/qtbase/src/plugins/sqldrivers/mysql# qmake "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/mysql -lmysqlclient_r" mysql.pro

Project ERROR: addExclusiveBuilds() requires at least two arguments

[SGaist]

Since you installed Qt 5.2 Why didn't you use the qmake from that Qt rather than the one from the system ?

[A Former User]

Well , I want to build mysql plugin for Qt 5.2 !
I get error message : QMySQL driver not found loaded.

I try test with a minimal code :

Main :

@
#include <QCoreApplication>
#include <QtSql/QSqlDatabase>
#include <QtSql>
#include <QDebug>

//remplacer l'affichage par la commande cout
#define q2c(string) string.toStdString()

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
   db.setHostName("localhost");
   db.setDatabaseName("qtdatabase");
   db.setUserName("root");
   db.setPassword("");
   bool ok = db.open();

return a.exec();

}
