However, debian/rules does: DEB_HOST_ARCH := $(shell dpkg-architecture -qDEB_HOST_ARCH) and does not define any other architecture variables. We should probably include /usr/share/dpkg/architecture.mk in debian/rules instead. Ben. -- Ben Hutchings Unix is many things to many people, but it's never been everything to anybody.
