Install mysql driver for qt in ubuntu
-
Make itself outputs all steps of build. It shows you all compiling and linking operations it runs.
If make was successfull it should create libqmysql.so file which you should place into plugins/sqldrivers folder
-
yes the libqmysql.so has been created and i copy it to the folder you specified. Now is it ready to use? can i start coding for in qt for mysql db?
-
Yes, all should be ok now. To check it just output content of
@
QSqlDatabase::drivers ()
@
QMYSQL should be there. -
thanks alot.
alittle more help will be appreciated. I have never used mysql in linux environment. I use it in windows by making web application in PHP. it is quit simple in windows because i just download wamp and install it and everything works perfectly i can create edit or delete databases and table through wamp very easily. i need alittle help here about how can i make database and tables in mysql in linux platform?
once again thanks alot for your help
-
You can either do it via console (by running mysql command) or you can install apache+php+phpmyadmin for web interface or you can install one of desktop GUI mysql clients.
-
well when i run mysql command it says this
@
the program "mysql" can be found in the following packages:
mysql-client-core-5.1
mysql-client-5.0
mysql-cluster-client-5.1
try sudo apt-get install <selected-package>
@which package should i install for creating databse
-
it depends on what server version do you have. You need client with same version.
-
Yes we've installed only driver for qt. If you want to store databases at your computer you need to install both mysql-server and mysql-client. If you will connect to remote database you can install only mysql-client.
-
Yes it should work. For better compatibility install client with exactly same version as your installed dev packages.
-
You SHOULD have mysql-server to be able to store and work with mysql databases at your computer.
Mysql-client is set of libraries and binaries which give access to mysql server (your or remote) for other applications or for you directly from console (mysql utility I'e mentioned before).
As I've seen earlier in thread you've installed mysql dev packages for mysql 5.0, so you need to install server and client versioned 5.0. -
ok i created a db "testTwo" in xampp. that db is in opt/lampp/var/mysql/testTwo folder. Now if i want to use this db then will code in my qt will get this db automatically when i provide QSqlDatabase db->setDatabaseName("testTwo"); or i need to copy this db somewhere else to make it available for qt?
-
I've never worked with xampp, but if it has mysql server in it and this server is running then all should be ok.
-
can you please check this thread i have some problem in loading mysql driver? "Your text to link here...":http://developer.qt.nokia.com/forums/viewthread/1208/
-
Yet can't install according to above.
Why I get@***Unknown option -lmysqlclient_r”@
when running
@qmake “INCLUDEPATH+=/usr/include/mysql” “INCLUDEPATH+=/home/paul01/QtSDK/Desktop/Qt/4.8.0/gcc/include/Qt” “LIBS+=-L/usr/lib/mysql -lmysqlclient_r” mysql.pro@
and next errors after make :

hope..it will help full -
Try OpenSUSE 11.4 and you will never find any problem ! Qt will be installed and well configured with KDE desktop :)
