Hi,

I'm a newbie here! I'm currently coding for IOCTL.
Need help to find solution in the following errors.

Undefined reference to '_imp__SetupDiGetClassDevsW@16'
Undefined reference to '_imp__SetupDiEnumDeviceInterfaces@20'
Undefined reference to '_imp__SetupDiGetDeviceInterfaceDetailW@24'
Undefined reference to '_imp__SetupDiGetDeviceRegistryPropertyW@28'
collect2: Id returned 1 exit status

I used QT version 4.8.1 for Desktop and
I already tried to add QT += qt3support in .pro file, but it didn't work.

Any help will be very much appreciated.
Thanks..
