That's because debian/rules needs to be cross-build-aware and the source package you're using as a test evidently isn't. There is no implicit support for cross-building; debian/rules is a makefile and needs to be written in a way that the correct options are passed to configure to support cross-building, whether that's via a helper such as dh7 or cdbs, or written out by hand in debian/rules (as would seem to be required for the 'hello' source package). I would recommend using an actual base package as a test case for cross-building, as these are much more likely to be set up for it already - whereas toy packages such as 'hello' would not be. > There's also a warning from dpkg-architecture which I don't really > understand. > dpkg-architecture: warning: Specified GNU system type > arm-linux-gnueabi does not match gcc system type i486-linux-gnu. That warning is output whenever dpkg-architecture is called with a -a option; you should obviously ignore it when cross-building. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
