Hi,
#include <ddk/ntddk.h>
This finds ddk/ntddk.h ok but then fails with :
C:/Rtools/mingw_64/x86_64-w64-mingw32/include/ddk/ntddk.h:38:17: fatal
error: wdm.h: No such file or directory
It can't find wdm.h because that's alongside ntddk.h in the ddk directory.
It's only looking in include not include/ddk, I think.
I've been searching and reading the documentation and I believe I can
create a file Makevars.win with a line PKG_CPPFLAGS = -I<something>/ddk
Is that correct? What should <something> be? i.e. the location of
windows.h which it finds fine.
I'm using latest Rtools.exe 3.4 via AppVeyor.
Thanks, Matt
