MySQL "libs & include" module not found

_Mark_

Hi!
I'm reading the documentation about how to use MySQL in Qt5 applications:

http://doc.qt.io/qt-5/sql-driver.html#qmysql

It says:

You need to get the MySQL installation files. Run SETUP.EXE and choose "Custom Install". Install the "Libs & Include Files" Module.

But I cannot find this module in the MySQL installation! I downloaded the last version of the community release.
Am I missing something obvious?

NetZwerg

For Windows:
Download the MySQL Server or the libmysqlclient c connector
When using the connector you can easily take the zip-only and extract this to some temporary directory.

You need to link against the libmysql.dll by having INCLUDEPATH set to include the mysql.h directory and LIBS set to include (-L) the lib-path and the library to link against (-l).

cd %QTDIR%/src/qtbase/src/plugins/sqldrivers/mysql
qmake "CONFIG+=release" "INCLUDEPATH+=C:/temp/mysqlconnector/include" "LIBS+=-LC:/temp/mysqlconnector/lib" "LIBS+=-llibmysql" mysql.pro
(n|mingw32-)make
(n|mingw32-)make install

For Linux:
Install the apropriate header files for your linux destribution.

Thank you! With your hints I successfully compiled the plugins, which are place into:

C:\Development\Qt\5.5\mingw492_32\plugins\sqldrivers

Now I'm facing the common issue of "QMYSQL driver not loaded but available". I read tons of thread about this but I'm asking some clarification about.

I checked the db server is up (from MySQL Workbench I can connect)
in the pro file of my test app I set:

QT += sql

this is my connection code:

    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
    db.setHostName("localhost");
    db.setPort(3306);
    db.setDatabaseName("test");
    db.setUserName("root");
    db.setPassword("");
    qDebug() <<  db.open();

in the documentation I cannot find the page where are described the requisites, like which libs to link with, etc...

EDIT:
the error is present only in debug mode1 In release it connect successfully! Anyway I have also qsqlmysqld.dll in the plugins folder.
