    Ok, i was googling the problem. I get the error in the Makefile.Release in line 65:

    @{......\sql\drivers\mysql}.cpp{.obj\release}.obj::
    $(CXX) -c $(CXXFLAGS) $(INCPATH) -Fo.obj\release\ @<<
    $<
    <<@

    I get the error in line "<<"

    I add before "<<" a tab, so "\T<<". After I fired the mingw32-make command I still got the same problem. It seems to me that the Make.Release and Make.Debug files are generated each time if I do the mingw32-make command.

    Where can I set this behavior?

    First thing to do is to delete that folder content and restart

    I have the same problem "Makefile.Release:65: *** missing separator"
    and i looked in Makefile.Release and didn't find missing separator)
    There were my steps:

    1. create folder [tempMySQL] with include and lib folders from mysqlserver folder
      It's look like this
      c:\qt\qt5.3.1\tempMySQL

    2. open mingw console and go to "C:\Qt\Qt5.3.1\5.3\Src\qtbase\src\plugins\sqldrivers\mysql"

    3. qmake "INCLUDEPATH+=C:\Qt\Qt5.3.1\tempMySQL\include" "LIBS+=C:\Qt\Qt5.3.1\tempMySQL\libmysql.lib" mysql.pro

    4. mingw32-make

    I didn't build Qt5.3.1 by myself, i just download
    Qt 5.3.1 for Windows 32-bit (MinGW 4.8.2, OpenGL, 737 MB) (Info) from here

    And when i worked with Qt 4.8.4 with VS2010 i didn't have a problem.
    I got all those steps then i describe above and it build and worked wihout any problem

    And of course i add mingw to PATH

    Is libmysql.lib the static MySQL client lib ?

    libmysql.lib it's static library. I got it from .../MySQL/MySQL Server 5.6/lib
    maybe i don't understand your question?

    Yes you understood it well. The thing is, on windows, static libraries and import libraries have the same extension but don't work the same. And furthermore, you can't mix mingw and MSVC libraries like that.

    Look at this "wiki entry":http://www.qtcentre.org/wiki/index.php?title=Building_the_QMYSQL_plugin_on_Windows_using_MinGW

    For the steps to use MinGW

    The same result(((...

    BUT:
    I found that i have MySQL drivers with official build of QT5.3.2))) I have no idea why i didn't see it in first time and spent much time trying to build this drivers)).
    And firstly it didn't work too. Finally i put libmysql.dll into ...\Qt5.3.2\5.3\mingw482_32\bin and it works.!

    I think that problem with my own building of these drivers is that i have VS10, VS12, and MinGW compiler on one OS.... When i'll have free time, maybe in this everning i'll try to build it by mingw on virt. mach with Win7 without another compilers

    Remark: i don't have an idea why - but reimp util from MINGW Utils works only in old version (0.3)

    Hello All,
    I do as following:
    C:\Qt\Qt5.1.1\5.1.1\Src\qtbase\src\plugins\sqldrivers\mysql>qmake "INCLUDEPATH+=C:\mySQL\include" "LIBS+=C:\mySQL\lib\libmysql.lib" mysql.pro

    C:\Qt\Qt5.1.1\5.1.1\Src\qtbase\src\plugins\sqldrivers\mysql>mingw32-make

    And go outpu like that:
    C:\Qt\Qt5.1.1\5.1.1\Src\qtbase\src\plugins\sqldrivers\mysql>mingw32-make

    Hi,

    Looks like your not linking to the MySQL library.

    LIBS+=-LC:/mySQL/lib -lmysql

    should be the correct syntax

    I know this is a very very old topic, but nonetheless somebody might benefit from this:

    I was able to compile the mysql driver like this:

    • Using Win10 home 64-bit
    • Installed QT 5.15.0 64-bit (mingw)
    • Installed mysql server 8.0.14 (located in C:\Program Files\MySQL\MySQL Server 8.0) and Connector C++ 8.0.15 (located in C:\Program Files\MySQL\Connector C++ 8.0. B. Both are 64-bit.
    • Started QT and opened C:\Qt\5.15.0\Src\qtbase\src\plugins\plugins.pro

    Modify mysql.pro like this (mind the forward slashes this was the last culprit why it didn't work here!):

    TARGET = qsqlmysql

INCLUDEPATH +='C://Program Files//MySQL//MySQL Server 8.0//include'
DEPENDPATH += 'C://Program Files//MySQL//MySQL Server 8.0//include'
LIBS += 'C://Program Files//MySQL//MySQL Server 8.0//lib//libmysql.lib'

HEADERS += $$PWD/qsql_mysql_p.h
SOURCES += $$PWD/qsql_mysql.cpp $$PWD/main.cpp

#QMAKE_USE += mysql

OTHER_FILES += mysql.json

PLUGIN_CLASS_NAME = QMYSQLDriverPlugin
include(C:\Qt\5.15.0\Src\qtbase\src\plugins\sqldrivers\qsqldriverbase.pri)
    • In QT Creator rightclick on the folder "mysql" and select "Build mysql"
    • Make sure to do above in both release and debug

    I found the files I needed in:
    C:\Qt\5.15.0\Src\qtbase\src\plugins\build-sqldrivers-Desktop_Qt_5_15_0_MinGW_64_bit-Debug\plugins\sqldrivers
    C:\Qt\5.15.0\Src\qtbase\src\plugins\build-sqldrivers-Desktop_Qt_5_15_0_MinGW_64_bit-Release\plugins\sqldrivers
