MySql Problem

[vishesh]

Hi,

I have Qt Application which is connected with MySql. In my machine its works fine.
But when i run it in a fresh machine Windows XP where QT and MySQL is not installed, the connection is not established with mysql. I added libmySQL.dll. Still it is not connected. Whether I need to add any other .dll?

Can please somebody tell me what i should do to make it work.

Do you have MySQL installed?

Do you have MySQL installed?

To clarify, this question means: "Did you copy the mysql client dll (from MySQL installation) to the target machine?"

I added libmySQL.dll. Still it is not connected.

Where did you place that DLL? It should be in the same directory where your executable is. Also check with Dependency Walker whether it doesn't need any additional DLLs.

Do you have qmysql.dll plugin (or whatever it's called) in sqldrivers subdirectory in the directory where your executable is?

[wysota]

To summarise, your directory tree should look like this:

yourapplicationbinary.exe
libmysql.dll (or whatever it is called)
qt-mt.dll
sqldrivers\
   +-------- qsqlmysql3.dll (or whatever it is called)

yourapplicationbinary.exe
libmysql.dll (or whatever it is called)
qt-mt.dll
sqldrivers\
   +-------- qsqlmysql3.dll (or whatever it is called)

To copy to clipboard, switch view to plain text mode 

Alternatively libmysql.dll and qt-mt.dll might be in your WINDOWS\System directory.

Thanks to everyone.

If MySql is installed in that machine, then it works fine.
