The system show you that you havn't Qt plugin for MySQL (you have SQLite) so try to build your own Qt MySQL plugin from https://qt-project.org/doc/qt-5.0/qtsql/sql-driver.html#qmysql

PS
I suppose you're using Qt5

anubhav87

Yes I am using Qt5

Try to use the mentioned steps above and don't forget to read documentation page I've linked it to you :)

Hi,
I am running below mentioned command

qmake "INCLUDEPATH+=/usr/local/include" "LIBS+=-L/usr/local/lib -lmysqlclient_r" mysql.pro
make

but it is saying
Cannot find file: mysql.pro

where will i get mysql.pro

mbnoimi

Where you've installed Qt5 on your machine?

anubhav87

My Home Folder (Linux Mint 14.0)

But i am still struggling with mysql.pro file where is this

mbnoimi

OK, try to do the following (considering installation directory is /home/usename/Qt5.0.2):

@usename@usename-pc ~ $ sudo apt-get install tasksel
usename@usename-pc ~ $ sudo tasksel install LAMP
usename@usename-pc ~ $ sudo tasksel install libmysqlclient-dev
usename@usename-pc ~ $ cd /home/usename/Qt5.0.2/5.0.2/Src/qtbase/src/plugins/sqldrivers/mysql
usename@usename-pc ~ $ /home/usename/Qt5.0.2/5.0.2/gcc_64/bin/qmake "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/x86_64-linux-gnu -lmysqlclient_r" mysql.pro
usename@usename-pc ~ $ make
usename@usename-pc ~ $ make install@

First of all, Could you please put the log inside code format.

give me the output of the following:
@cd ~
find ./ -name "mysql.pro"@

anubhav87

I find query.txt located on my desktop it gives the correct location but for mysql.pro it return nothing

username@username ~ $ find ./ -name "query.txt"
./Desktop/query.txt
username@username ~ $ find ./ -name "mysql.pro"
username@username ~ $

It seems that you didn't install Qt into your home directory. Try to run find where Qt installed.

anubhav87

Below is the path where i have installed my qt
/home/myusername/Qt5.0.0

mbnoimi

Try to download recent Qt installer (currently 5.0.2) , through installation wizard choose all available components (it has Qt' source code). Then:

@cd ~
find ./ -name “mysql.pro”@
