[SOLVED] undefined reference to GUID_DEVINTERFACE

undefined reference to GUID_DEVINTERFACE_XXX

I am trying to use GUID_DEVINTERFACE_DISK (or _FLOPPY... etc) in function SetupDiGetClassDevs, but g++ still don't build because of an undefined reference.

I have linked to with SetupAPI and incuded nstddstor.h as requiered (http://msdn.microsoft.com/en-us/library/windows/hardware/ff545824%28v=vs.85%29.aspx).

I saw that including initguid.h may resolve the problem, but it doesn't for me.

Also, when I try affecting a GUID variable as GUID g = GUID_DEVINTERFACE_DISK; and if I put my mouse on GUID_DEVINTERFACE_DISK, eclipse shows me where is it defined (nstddstor.h), but after compiling, it still doesn't work.

Any solutions ?

Solution

I don't have the Windows DDK handy and so I can't verify it but a user on another forum reports that it works by including initguid.h before ntddstor.h, so the following might work:

#include <initguid.h>
#include <ntddstor.h>
#include <Setupapi.h>

// Code copied from:

int main(void) {
    HDEVINFO hDevInfo;
    hDevInfo = SetupDiGetClassDevs(&GUID_DEVINTERFACE_VOLUME,
        NULL, NULL, DIGCF_PRESENT | DIGCF_INTERFACEDEVICE);
}
