Not sure, what you mean? What is 'package'? Are you trying to populate $SYSROOT? You might be able to do that from binary packages, using debootstrap or multistrap. > With cross-build dpkg-support: > ============================== > Set up where the cross tools and target headers, libraries and > executables are located. > cd package > DEB_BUILD_GNU_TYPE=$BUILD DEB_HOST_GNU_TYPE=$TARGET dpkg-buildpackage -b > That will create .debs to be installed on the target box or in $SYSROOT. Actually, not all packages support cross compilation, you might need to check, proper way would be by setting -a$ARCH flag. So, dpkg-buildpackage -b -ahurd-i386 (+extra flags) > The gnat issue is related but separate from the above description.
