    And what do you get if your run ldd on Qt's mysql plugin ?



  • I don't understand ! I,m new on Qt ...
    Of course I use XAMPP for testing MySQL Database.

    my code for test on console app :

    @
    #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"); // This is the line I got error
       db.setHostName("localhost");
       db.setDatabaseName("qtdatabase");
       db.setUserName("root");
       db.setPassword("");
       bool ok = db.open();
    
    return a.exec&#40;&#41;;
    

    }

    @

    return this errors :

    QSqlDatabase: QMYSQL driver not loaded
    QSqlDatabase: available drivers: QSQLITE QSQLITE2 QMYSQL QMYSQL3 QPSQL7 QPSQL

    but with this code :

    @
    #include <QCoreApplication>
    #include <QtSql/qsql.h>
    #include <QtSql/qsqldatabase.h>
    #include <QtSql/QSqlError>
    #include <QtSql/QSqlQuery>
    #include <QDebug>

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

    QStringList drivers = QSqlDatabase::drivers();
        for(int i = 0; i < drivers.count(); i++)
            qDebug() << drivers.at(i);
    
    return a.exec(&#41;;
    

    }

    @

    return this output:

    "QMYSQL","QMYSQL3" and ...

    Qt's MySql plugin is call libqsqlmysql.so, call ldd on it and check that it can find all dependencies



  • [quote author="SGaist" date="1388524196"]Qt's MySql plugin is call libqsqlmysql.so, call ldd on it and check that it can find all dependencies[/quote]

    what is your mean of ldd ? I have libqsqlmysql.so file in below address :

    /opt/Qt5.2.0/5.2.0/gcc_64/plugins/sqldrivers


  • Lifetime Qt Champion

    ldd is a little utility that lists the dependencies of an executable/dynamic library



  • [quote author="SGaist" date="1388526680"]ldd is a little utility that lists the dependencies of an executable/dynamic library[/quote]

    How can I check this option ? This is installed utility on OS or Qt ?
    Please give me more information about this.
    How to call ldd?

    I now install Qt on Windows for check my problem but now show error for load..

    "here":http://bit.ly/1l2bNYY

    Did you install MySQL on Windows ? Do you have the MySql dll somewhere accessible in your PATH ?

    Yes I have it on below path :

    C:\Program Files\MySQL\MySQL Server 5.6
    and
    C:\Program Files (X86) \MySQL\MySQL Server 5.6

    and on Linux ubuntu too

    On Windows I use of qt-windows-opensource-5.2.0-mingw48_opengl-x86-offline.exe and qt-windows-opensource-5.2.0-msvc2012-x86_64-offline.exe

    but I don't know why doesn't work :(


  • Lifetime Qt Champion

    You didn't answer the questions:
    What does ldd return ?

    Is the MySql dll folder in your PATH variable ? Or at least in the PATH environment variable in the run section of the Project panel in Qt Creator ?



  • For Windows...

    MySql dll folder :
    I have libmysql.dll and libmysql.lib and mysqlclient.lib here C:\Program Files\MySQL\MySQL Server 5.6\lib

    and I have qsqlmysql.dll and qsqlmysqld.dll and other files in here :

    C:\Qt\Qt5.2.0-MG\5.2.0\mingw48_32\plugins\sqldrivers
    and
    C:\Qt\Qt5.2.0\5.2.0\msvc2012_64\plugins\sqldrivers



  • and For Linux about ldd :

    root@Gigabyte-Z68P-DS3:~# ldd /bin/date
    linux-vdso.so.1 => (0x00007fff31d72000)

    and about MySQL plugin folder and files:

    in here :

    /opt/Qt5.2.0/5.2.0/gcc_64/plugins/sqldrivers .... I have libqsqlmysql.so


  • Lifetime Qt Champion

    I know where your dlls are. If using 64bit, the question is: is "C:\Program Files\MySQL\MySQL Server 5.6\lib" contained in the PATH environment variable in the Run section on the Project panel in Qt Creator ?

    I didn't ask you to run ldd on /bin/date but on your Qt 5.2.0 libqsqlmysql.so

    OMG! NO...
    Sorry ! I forget PATH environment variable !!! now my problem is sloved on Windows by add PATH environment variable for Mysql :)

    but for linux ?! can you give me more information ?


  • Lifetime Qt Champion

    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)

    did you call make after that ?

    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.

    Did you retry to run qmake now ?



  • [quote author="SGaist" date="1389256104"]Did you retry to run qmake now ?[/quote]

    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


  • Lifetime Qt Champion

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



  • 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&#40;&#41;;
    

    }

    @

    and .pro :
