[Qemu-devel] [Bug 1543057] Re: Warnings are treated as errors

[Peter Maydell]

(a) That warnings are treated as errors  is a feature, not a bug (it happens 
for development builds only)
(b) the definition of struct PCIDevice in include/hw/pci/pci.h starts with 
"DeviceState qdev;" so it's not clear to me how that error could be produced in 
the first place

I see the original submitter was using 2.2.50 -- I suggest using either
(a) a release build of QEMU or (b) current master. 2.2.50 will be from
somewhere on trunk between 2.2 and 2.3, so might quite possibly have had
a build bug that was quickly fixed subsequently.
