Current SVN (r410) holds a fairly complete set of emdebian-tools
scripts and I'm preparing for a 0.0.2 release and upload to Debian
unstable.
i.e. it needs testing!
:-)
Does anyone fancy being co-maintainer in Debian?
The result of emdebian-tools is that a new Emdebian developer should
only need to do:
$ sudo apt-get install emdebian-tools
$ emsetup --verbose --simulate
# check that the output is acceptable, nothing changed yet.
$ emsetup
If ~/.dpkg_cross/cross_compile isn't fully configured yet, (hint in the
manpage), then emsetup requests the use of --arch to determine the
target architecture:
$ emsetup -v -s --arch m68k
# check that the output is acceptable, nothing changed yet.
$ emsetup -a m68k
I'm thinking that a wishlist bug against dpkg-cross could be handy so
that dpkg-cross maybe uses debconf to ask the user for a default target
architecture. emdebian-tools can't configure cross_compile itself
because that conffile belongs to dpkg-cross.
I considered (and spent hours experimenting with) debconf for
emdebian-tools but in the end, it failed to meet the need - principally
because I couldn't find a way for debconf to a) update the (locked)
apt-get package list after inclusion of a new repository and b) install
packages from that repository where the package list has to be
generated from other debconf input (namely the chosen target
architecture). Hence, a new script: emsetup.
Doing it this way also means there are no dependencies on the installed
toolchain packages - instead the scripts handle checking for the
toolchain at runtime.
So we have a potential two step process, with an advisory to make it
three.

Description: emdebian crossbuilding tool set
A collection of scripts to ease cross-building Debian packages for
Emdebian, reducing package size, separating translations into
individual files and handling dependencies.
.
emsetup : Check your system for cross-build support and determine some
defaults for other emdebian-tools scripts. Run this first, using the
simulate option to see what changes may be needed.
.
emchain : Toolchain builder for cross compiling. If a pre-built
toolchain is not found or not available, emchain can build a custom
toolchain for your needs using the current Debian version of gcc.
.
em_make : Emdebianise a Debian package. Creates suitable changelog
entries, omits certain debhelper scripts from debian/rules and
maintains a patchset for emdebian. Removes all documentation and udeb
packages from debian/control.
.
emlocale : Moves all translations out of the Debian package(s) and into
individual locale packages, allowing the embedded user to only install
the translations that are relevant to that system. First run is via
em_make, subsequent runs update the list of available translation
packages.
.
emdebuild : Emdebian version of debuild that handles cross-building the
emdebianised tree. Requires a suitable cross-building toolchain to be
installed for the requested architecture, e.g. gcc-4.1-arm-linux-gnu,
available from the emdebian tools repository via emsetup or built for
your particular configuration using emchain.
.

A demo arch _all.deb for 0.0.2 is in my apt repository:
http://linux.codehelp.co.uk/packages/pool/main/e/emdebian-tools/
There'll be some more updates and corrections before it's actually
released in emdebian SVN (with --svn-tag) and then uploaded to the
Debian new queue. I'm currently waiting for the ITP bug number.
Future versions of emdebian-tools may include more scripts / tools -
including possibly empath.
