    Default Re: Issue Installing QMYSQL Driver

    Hi, I need to use Mysql in Qt, so I found how to install the QMYSQL driver in this guide.

    I tried with the last version of MySQL Server (5.6), but when I tried to make, I got a lot of undefined errors, trying with older versions, I could finally build the libraries (I used mysql-noinstall-5.0.90-win32.zip) in the debug folder, and the libraries are qsqlmysqld4.dll and libqsqlmysqld4.a, when the guide says:

    Run make - this should build the qsqlmysql4.dll, libqsqlmysqld4.dll, qsqlmysql4.a and libqsqlmysqld4.a files in the %QTDIR%/plugins/sqldrivers directory.
    What's wrong?

    There's the build log:

    Qt Code: 
    1. C:\Qt\4.8.4\src\plugins\sqldrivers\mysql>qmake -o Makefile "INCLUDEPATH+=C:/Progra~2/MySQL/MYSQL-~1.90-/include" "LIBS+=C:/Progra~2/MySQL/MYSQL-~1.90-/lib/opt/liblibmysql.a"

    PD: I could build the libraries thanks to a guy who had the same problem and said that he solved it with MySQL 32bits, while 64bits broughts him problems. But as I said, I don't get the libraries which I need.

    I've installed Qt 4.8.4 SDK under Code::Blocks and Windows 7 Ultimate 64-bits.

    Sorry if bad english and sorry if there isn't the appropriate forum. Best regards.

    Default Re: Issue Installing QMYSQL Driver

    Well, I tried "make release" and now I get qsqlmysql4.dll and libqsqlmysql4.lib in the release folder, I copy them into plugins folder but Qt doesn't load it.

    the guides says what when I type "make" in the Qt command prompt, the libraries should appear in the plugin folder, but it doesn't, it only makes it on debug or release folder.

    There is my C:\Qt\4.8.4\plugins\sqldrivers folder:
    Qt Code: 
    1. 27/05/2013  06:34    <DIR>          .
    2. 27/05/2013  06:34    <DIR>          ..
    3. 26/11/2012  13:54             2.168 libqsqlite4.a
    4. 26/11/2012  13:54             2.178 libqsqlited4.a
    5. 27/05/2013  06:31             2.182 libqsqlmysql4.a
    6. 27/05/2013  06:29             2.192 libqsqlmysqld4.a
    7. 26/11/2012  13:53             2.178 libqsqlodbc4.a
    8. 26/11/2012  13:53             2.182 libqsqlodbcd4.a
    9. 26/11/2012  13:54           529.408 qsqlite4.dll
    10. 26/11/2012  13:54         1.898.887 qsqlited4.dll
    11. 27/05/2013  06:31            80.896 qsqlmysql4.dll
    12. 27/05/2013  06:29           782.587 qsqlmysqld4.dll
    13. 26/11/2012  13:53           164.352 qsqlodbc4.dll
    14. 26/11/2012  13:53           999.200 qsqlodbcd4.dll

    I tried to:
    Qt Code: 
    1. qDebug() << QSqlDatabase::drivers(); // returns me only ("QSQLITE", "QODBC3", "QODBC")
