I have a matrix of various qemu.git#stable-x.y that build against xen.git#staging*. Since some months qemu.git#stable-2.x fails to build against xen.git#staging. qemu-2.10+ works with staging. To me it is not clear how to fix this failure:
qemu-2.9-20170907T112512.4cd42653f5/include/hw/xen/xen_common.h:61:16: warning: implicit declaration of function 'xc_map_foreign_bulk'
qemu is built with the various compat flags like :-DXC_WANT_COMPAT_MAP_FOREIGN_API=1. I think this should give access to that function. But for some reason the missing function is wrapped further in xenctrl_compat.h.
Is qemu-2.x supposed to define XC_BUILDING_COMPAT_MAP_FOREIGN_API? Commit 3248691679 ("tools: Refactor foreign memory mapping into libxenforeignmemory") in xen.git indicates that just XC_WANT_COMPAT_MAP_FOREIGN_API would be needed.
