<![CDATA[Unable to find drivers for msyql.]]>Hello,

I have successfully compiled QMYSQL drivers, and can load them on a machine where Qt is installed. When I copy my executable and the required dlls to another computer however (where Qt is not installed), I get driver not loaded. Here is what is copied to client's computer during install, which should be everything that is necessary:

app_folder
-->myApp.exe
-->libmysql.dll, qsqlmysql4.dll, qsqlmysqld4.dll, qtsql4.dll, qtsqld4.dll, qtcore4.dll, qtcored4.dll, qtgui4.dll, qtguid4.dll.

In the pro file I simply link to drivers using:
LIBS += "libmysql.lib"
LIBS += "qsqlmysqld4.lib"

Both are in the project directory.

Any suggestions would certainly be helpful.

It turns out, that on the client's machine, qsqlmysqld4.dll needs to reside in a subdirectory of the application's executable directory, called sqldrivers, like so:

app_folder
myApp.exe
libmysql.dll, others
sqldrivers (folder)
qsqlmysqld4.dll

Putting it there solved it.
