[Mingw-users] undefined reference to 'GUID_DEVINTERFACE_DISK' from ld

[mwesten <mw...@ve...>]

Hi - I'm using Qt 4.6.3 with MinGW on Win32 to compile a program which calls 
SetupDiGetClassDevs with a ClassGuid of GUID_DEVINTERFACE_DISK and cannot 
get it to link.  I have added -lsetupapi to link with that library, but the 
error remains.  What am I doing wrong?  Thanks!
