Deploy qt desktop app 'Driver not loaded'
-
Hi, I'm new in the forum ...
Recently I have been developing an QT desktop application, using mysql drivers and MSVC 2017 x64.
I use this configuration to add libmysql.lib to mysql 5.7 driver (I use Laragon MYSQL DB 64 bits)
Mysql driver from : https://dev.mysql.com/downloads/mysql/5.7.html
Code generate from qt add library
win32:CONFIG(release, debug|release): LIBS += -LC:/Users/Adrian/Desktop/mysql-5.7.26-winx64/lib/ -llibmysql
else:win32:CONFIG(debug, debug|release): LIBS += -LC:/Users/Adrian/Desktop/mysql-5.7.26-winx64/lib/ -llibmysqldWith the qtcreator that conf work fine, but when I deploy my project I have problems with the mysqldriver
I use this comand to deploy : 'windeployqt myapp.exe ' and 'windeployqt . '
I've been looking for a solution, but I'm going 2 days and nothing happend.
I tried : add .lib and .include dir in Environment Variables, add libmysql.dll and others dll in C:/Windows and paste .lib mysql to D:\Programas\QT\5.12.3\msvc2017_64\plugins\sqldrivers and also in my release/sqldrivers after the deploy
Sorry, my english is no so good
-
I found the solution:
#include "controlador.h" #include "qmessagebox.h" controlador::controlador() { } static QSqlDatabase con=conexion().conecta();
to
usuario controlador::logear(acceso ac) { usuario us= usuario(); QSqlDatabase con=conexion().conecta(); QSqlQuery query(con);
#include "vistas/login.h" #include <QApplication> int main(int argc, char *argv[]) { QApplication::libraryPaths(); QApplication a(argc, argv); login w; w.show(); return a.exec(); }
https://forum.qt.io/topic/66480/deploy-on-windows/14
I think because static db conection, windeployqt work fine
-
Hi and welcome to devnet,
First and very important thing: NEVER put anything in "C:/Windows", that's a pretty bad thing to do that can have major consequences on your installed software.
You should only need to copy the MySQL dll(s) in the same folder as your application.
-
I meant in the same folder as your executable.
-
I change mysql version to 8.0, using workbrench to create the database. Using c++ conector
Add mysqlcppconn.lib
copy and paste this dll in executable folder
copy and paste this dll in executable folder /sqldrivers
But, I had mysql driver not loaded
Also I tried to connect using ODBC Mysql
The conection between the database work fine, but I can't execute query like 'SELECT ID_usuario,nombre,apellido,dni,telefono,correo,cargo,direccion FROM usuario WHERE user = :user and pass = :pass; ', all return -1 in query.size, is the same code that I used in qmysql , query.lastError().text() return empty
-
You can set the
QT_DEBUG_PLUGINS
environment variable to check what is going on with them. -
@SGaist Yes, I add QT_DEBUG_PLUGINS = 1 in qtcreator system enviroment
When I deploy my app with windeploy and run in qtcreator (is equal to open .exe app) release

The very first object you must create is a QCoreApplication (or QQuiApplication/QApplication) otherwise the required internals won't be initialised.
-
@SGaist Do you mean to main.cpp?
This is my main.cpp
#include "vistas/login.h"
#include <QApplication>int main(int argc, char *argv[])
{
QApplication a(argc, argv);
login w;
w.show();return a.exec();
}
If change to QCoreApplication
#include "vistas/login.h"
#include <QCoreApplication>int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
login w;
w.show();return a.exec();
}
QWidget: Cannot create a QWidget without QApplication
16:27:10: The program has unexpectedly finished.
16:27:10: The process was ended forcefully.
16:27:10: D:/Proyectos/Proyecto_Restaurante_Qt/build-restaurante_tunqui-Desktop_Qt_5_12_3_MSVC2017_64bit-Release/release/restaurante_tunqui.exe crashed. -
The ODBC failure you had was because of a missing QCoreApplication based object.
Your current error comes from the fact that you are trying to show a widget while you created only a QCoreApplication. Qt widgets requires a QApplication object.
-
@SGaist I don´t understand , do you mean this error to QODBC?
QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers:
QSqlDatabase: an instance of QCoreApplication is required for loading driver plugins
"Driver not loaded Driver not loaded"This is QMYSQL error when I deploy my app and run. QTCreator gives me a better error report instead of opening my .exe app
Sorry if I also confused him by using 2 drivers
-
QMYSQL work fine with qtcreator, but no after deployment
-
QODBC only open database in qtcreator , but no work SELECT (I use the same queries for both)
Conection file conexion.cpp
#include "conexion.h" conexion::conexion() { } QSqlDatabase conexion::conecta() { /*QSqlDatabase db; db = QSqlDatabase::addDatabase("QMYSQL"); db.setHostName("localhost"); db.setUserName("root"); db.setPassword(""); db.setDatabaseName("tunqui_restaurante");*/ QSqlDatabase db = QSqlDatabase::addDatabase("QODBC"); db.setDatabaseName("Driver={MySQL ODBC 8.0 ANSI Driver};Server=localhost;DATABASE=tunqui_restaurante;"); db.setUserName("root"); db.setPassword(""); if (db.open()){ qDebug() << "true"; } else { qDebug() << db.lastError().text(); } return db; }

int main(int argc, char *argv[]) { QApplication a(argc, argv); // <--- HERE login w; w.show(); return a.exec(); }
-
@jsulm said in Deploy qt desktop app 'Driver not loaded':
int main(int argc, char *argv[])
{
QApplication a(argc, argv); // <--- HERE
login w;
w.show();return a.exec();
}
I don't understand. What should it be there?
If I change QApplication for QCoreApplication = QWidget: Cannot create a QWidget without QApplication
Sorry I'm newbie using the QMySQL driver and libmysql.dll
The problem is after deploying my desktop app.
-
@AdrianN17 said in Deploy qt desktop app 'Driver not loaded':
QApplication
instead of QCoreApplication.
-
@AdrianN17 If you have "Cannot create a QWidget without QApplication" error with QApplication, then you're creating QWidget based class instance somewhere before QApplication instance is created. You need to check that. Do you have any static objects?
-
@jsulm I only was tested using a QCoreApplication instead QApplication :
@SGaist said in Deploy qt desktop app 'Driver not loaded':
The very first object you must create is a QCoreApplication (or QQuiApplication/QApplication) otherwise the required internals won't be initialised.
Because I have that problem when I deploy and execute my app:
QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers:
QSqlDatabase: an instance of QCoreApplication is required for loading driver plugins
"Driver not loaded Driver not loaded"Because so far, I only had that error doing the test. The only problem really is with QMysql driver not loaded
Excuse me if I confused you
-
@AdrianN17 said in Deploy qt desktop app 'Driver not loaded':
I only was tested using a QCoreApplication instead QApplication
Again: if you're using widgets in your app you have to use QApplication.
And if you then have that error message then please check whether or not you're creating any QWidget based objects before QApplication or post whole code here, so we can check. Else I can't help you. -
