Undefined reference to '_imp__SetupDiGetClassDevsW@16' error

[yson]

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..

first clean the project, qmake and rebuild it if doesn't worked then the library has some problems and is better to re-install it!

Hi alizadeh91,

Thanks for your response, but after clean, qmake, and rebuild the project, it still didn't work.
Then after re-install Qt, it's still error.. I already included setupapi.h. Did I missed something to include?
For additional info, I'm using a 64-bit platform. Is it possible that the error is related to that environment?

Thanks!

i'm afraid not!. can you build a simple example with your qt (without qt3support module)???

Hi,

I already fixed the problem..
After including setupAPI.lib path in the .pro file, no more error occurs.

Btw, thanks alizadeh91 for the responses. Very much appreciated.
