A cross build (mingw32 on debian) also results in this linker error. The reason is quite simple: tap.o (which provides tap_get_vhost_net) is only build for posix systems, but not for windows: Makefile.objs:net-nested-$(CONFIG_POSIX) += tap.o Changing this does not help because tap.c does not compile for win32 without errors. Either these errors have to be fixed, or don't call tap_get_vhost_net when compiling for win32. Stefan
