Just install libqt4-sql-mysql package if you use Qt from repository. If you use Qt built from sources, than you need to install mysql-dev headers and libraries and build mysql plugin from src/plugins/sqldrivers/mysql.

i followed steps in this url

http://prres.wordpress.com/2010/05/17/configure-mysql-database-driver-for-qt/ [prres.wordpress.com]

the first is done perfect but the second step is not working for me. when i do first line in second step it displays this

when i checked these directories “/usr/incluce/mysql” and “/usr/lib/mysql” it was present there after doing first steps

Looks like you’ve forgotten space and qt path in your command. For example in my system qt sources are in /usr/src/qt, so commands for me will be:

when i was installing qt creator it tells me this path /opt/sqt

You need not libraries, but sources. I don’t remember if they are distributing with Qt SDK. Look for folder src somewhere in /opt/qt

ok i found opt/qt and sub directories in it. Now when i run qmake command it says this

Looks like it can’t find mkspecs/features folder (with prf file describing this replace function).

any help what should i do now?

As a quick solution you can rebuild Qt library from source :)

Another way:
Look into your built Qt library for file mkspecs/features/qt_functions.prf. If it isn’t there copy this file from src folder, it should help I think.

“Failure to open file opt/qtsdk-2010.05/qt/src/plugins/sqldrivers/mysql/MakeFile”

I just saw this error today when I was trying to compile a Qt Example. Verify that you have writing permission in the /opt/qt folder.

hi i checked the file you specified. its here on my pc /home/qt/qt/mkspecs/qt_functions.prf.

so how can i run qmake command?

Where is your Qt instance located?

what do you mean qt instance??

can you tell me what do you mean by qt instance?

i changed file permissions now it displays this error
“qpluginbase.pri:10: Unknown Replace Function: qtLibraryTarget”
