[SOLVED] MySQL-Plugin for QT 5.3.1 under OsX 10.9

SGaist

macports and brew are package manager for OS X, install one of them, and from there install MySQL

babuschkainyouface

ok what i did
i downloaded: https://distfiles.macports.org/MacPorts/MacPorts-2.3.1-10.9-Mavericks.pkg

installed it
then i opened a terminal and entered:

xcode-select --install

after that i entered:

sudo port install qt5-mac-mysql56-plugin

but i still get the same error :

QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7

shall i do a

sudo port install mysql56

or

sudo port install mysql56-server

??

SGaist

With that command you installed the Qt 5 version from macport. So you probably have also MySQL 5.6 already installed

babuschkainyouface

sorry sgaist - is that a question? i am not sure ?

as mentioned before

i have a debian server running mysql community server

i got a macbook with QT 5.3.1 creator on it

i want to open a connection from the macbook to the mysql community server on the debian server

i am not sure if this is working ..

maybe it is better to start from the beginning
so which version of the QT 5 shall i download an install on my macbook ?

SGaist

@port installed | grep -i mysql@

You'll see what MySQL package you installed.

Probably located in /opt/local/lib/mysql56/mysql

babuschkainyouface

port installed | grep - i mysql

brought up this:

mysql56 @5.6.19_1 (active)
mysql56-server @5.6.19_1 (active)
mysql_select @0.1.2_0 (active)
qt5-mac-mysql56-plugin @5.3.1_0 (active)

in /opt/local/lib/mysql56/mysql
was:

libmysqlclient.18.dylib
libmysqlclient.a
libmysqlclient.dylib
libmysqlclient_r.18.dylib
libmysqlclient_r.a
libmysqlclient_r.dylib
libmysqld.a
libmysqlservices.a

SGaist

So you have what is need. No the only thing is that your plugin point to mysql55 and not mysql56.

Have a look at the install_name_tool command to change that in your plugin

babuschkainyouface

how do i change that ?

SGaist

By using the install_name_tool command

babuschkainyouface

can u tell me where do i find this tool and how do i use it?

never heard of that before .. still searching on google

SGaist

It's an OS X command line tool

There are several posts on this forum that mention it on problem similar to yours

babuschkainyouface

really i found lot of articles on google - but i really have no clue how to use that tool ..
can you maybe give me a hint please?
thanks in advance

SGaist

in a console write

@man install_name_tool@

Everything is explained

babuschkainyouface

ok i gave up ..
i tried nearly everything that is suggested on :
http://stackoverflow.com/questions/6282889/install-name-tool-does-nothing
or
http://qt-project.org/doc/qt-5/macosx-deployment.html

i could not make it work with the install_name_tool

so i changed the name of the mysql56 to mysql55 in /opt/local/lib

it seemes to work now - i hope it gives no problems ..

thanks for help, B

SGaist

Do you mean

@install_name_tool -change /opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib
/opt/local/lib/mysql56/mysql/libmysqlclient.18.dylib libqsqlmysql.dylib@

Didn't work ?

babuschkainyouface

thank you very much - as u know i am a starter but you helped me really out of that problem
