Source: anna Section: debian-installer Build-Depends: debhelper (>= 5.0.22), dpkg-dev (>= 1.7.0), libdebconfclient0-dev (>= 0.46), libdebian-installer4-dev (>= 0.41)
Fetch and install cross compiling libraries (XXX Need to test mrvn tool)
sudo apt-cross -a armel -f -i libdebconfclient0 sudo apt-cross -a armel -f -i libdebconfclient0-dev sudo apt-cross -a armel -x libdebian-installer4 -x libdebian-installer-extra4 -f -i libdebian-installer4-dev sudo apt-cross -a armel -f -x libc-bin -x libc-dev-bin -i libc6-dev sudo apt-cross -a armel -f -x libc-bin -i libc6 E: sudo apt-cross -a armel -f -x libc-bin -x libc-dev-bin -i dpkg-dev ( I do not think you really need dpkg-dev to be able to cross-compile the package )
