Hi Dmitry,

I disagree. Just because we have rte_windows.h to properly plug Windows SDK

Hi Nick,
Thanks for detailed explanation. It can be reproduced even without DPDK:
#include
#include
int
main(int argc, char **argv) {
return (int)&GUID_DEVCLASS_NET;
}
This links with clang, but not with MinGW-w64. AFAIK, it should not link,
because INITGUID is not defined. @DmitryM, @Nat
Build OS is Windows 10 2004
I can't seem to reproduce the link error you've mentioned (I'm building
hello_world on master).
can you share more information on how to reproduce it? (MinGW version, build
env variables, build OS).
Thanks,
Tal.
Hi Tal,
Sure - latest MinGW-w64 (v8.0.0 I believe, but the versioning isn't

Hi Nick,

Linking with the 'pci' driver when building with MinGW on
Windows fails with undefined symbol 'GUID_DEVCLASS_NET'.
This occurs because devguid.h is included in rte_windows.h
before INITGUID is defined.
Resolved by moving the include of devguid.h after the definition
of INITGUID.
