[SOLVED]Trying to build mysql driver in Qt 5.1.0 and MySQL 5.6

morker

Thanks for your post's!

I got an issue if I want to build my driver. I'm using qt 5.3 and mysql 5.6 (mysql-5.6.20-win32).

I added mysql.pro to qt creator and add the following two lines to the .pro file:

@
LIBS += C:/mysql/mysql-5.6.20-win32lib/libmysql.lib
INCLUDEPATH += C:/mysql/mysql-5.6.20-win32/include
@

I got the following errors if i want to compile the mysql project:

C:\mysql\mysql-5.6.20-win32\include\mysql_com.h:320: error: C2146: Syntaxfehler: Fehlendes ';' vor Bezeichner 'fd'

C:\mysql\mysql-5.6.20-win32\include\mysql_com.h:320: error: C4430: Fehlender Typspezifizierer - int wird angenommen. Hinweis: "default-int" wird von C++ nicht untersttzt.

C:\mysql\mysql-5.6.20-win32\include\mysql_com.h:320: error: C2146: Syntaxfehler: Fehlendes ';' vor Bezeichner 'fd'

C:\mysql\mysql-5.6.20-win32\include\mysql_com.h:320: error: C4430: Fehlender Typspezifizierer - int wird angenommen. Hinweis: "default-int" wird von C++ nicht untersttzt.

C:\work\build\qt5\qtbase\src\sql\drivers\mysql\qsql_mysql.cpp:44: error: C1083: Datei (Include) kann nicht ge”ffnet werden: "QtSql/private/qsqldriver_p.h": No such file or directory

Many thanks for your help!

Hi and welcome to devnet,

Did you first build Qt 5 yourself ?

morker

Hi SGaist,

yes I built qt5 by my self. I also tried to build the drivers with the following commands (see http://qt-project.org/doc/qt-4.8/sql-driver.html#how-to-build-the-qmysql-plugin-on-windows):

cd C:\work\build\qt5\qtbase\src\plugins\sqldrivers\mysql

qmake "INCLUDEPATH+=C:\mysql\mysql-5.6.20-win32\include" "LIBS+=C:\mysql\mysql-5.6.20-win32\lib\libmysql.lib" mysql.pro

mingw32-make

If I do the "mingw32-make" command I got the following errors:

C:\work\build\qt5\qtbase\src\plugins\sqldrivers\mysql>mingw32-make
mingw32-make -f Makefile.Release all
mingw32-make[1]: Entering directory 'C:/work/build/qt5/qtbase/src/plugins/sqldri
vers/mysql'
Makefile.Release:65: *** missing separator. Stop.
mingw32-make[1]: Leaving directory 'C:/work/build/qt5/qtbase/src/plugins/sqldriv

mingw32-make[1]: Leaving directory 'C:/work/build/qt5/qtbase/src/plugins/sqldriv

Makefile:40: recipe for target 'release-all' failed
mingw32-make: *** [release-all] Error 2

SGaist

You're on windows either escape the backslashes or since you are using Qt use the unix notation i.e. forward slashes

morker

I'm working on a windows machine. You can see in my post that I'm setting the INCLUDEPATH and the LIBS with \

What means this error exactly:

Makefile.Release:65: *** missing separator. Stop.

SGaist

I know you are, and I already wrote the options you have:

escape the \ so in practice use \
Since you are using Qt use /

Second option is cleaner.

morker

Sorry for that stupid questions. I'm using the QT 5.4.0 64-bit for Desktop (MSVC 2013) command line.

I got the same errors if I'm setting the paths like:

qmake "INCLUDEPATH+=C:\mysql\mysql-5.6.20-win32\include" "LIBS+=C:\mysql\mysql-5.6.20-win32\lib\libmysql.lib" mysql.pro

or:

qmake "INCLUDEPATH+=C:/mysql/mysql-5.6.20-win32/include" "LIBS+=C:/mysql/mysql-5.6.20-win32/lib/libmysql.lib" mysql.pro

or does it mean that I have to set the slashes in the Makefile.Release instead of \ to /

Many thanks.

morker

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?

SGaist

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

Dark2011

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:

create folder [tempMySQL] with include and lib folders from mysqlserver folder
It's look like this
c:\qt\qt5.3.1\tempMySQL
open mingw console and go to "C:\Qt\Qt5.3.1\5.3\Src\qtbase\src\plugins\sqldrivers\mysql"
qmake "INCLUDEPATH+=C:\Qt\Qt5.3.1\tempMySQL\include" "LIBS+=C:\Qt\Qt5.3.1\tempMySQL\libmysql.lib" mysql.pro
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

Dark2011

remark: when i build this driver for Qt4.8.4 and VS2010 i used nmake, of course)

SGaist

Is libmysql.lib the static MySQL client lib ?

Dark2011

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

SGaist

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

Dark2011

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:

What Im doing wrong?

SGaist

Hi,

Looks like your not linking to the MySQL library.

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

should be the correct syntax

Peter Van Grieken

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
