The majority of an Emdebian rootfs for ARM [0] is now built using the composite method but it isn't ready for use - yet. You can see the status using edos-debcheck [1]: $ apt-cross -u -m http://www.emdebian.org/emdebian/ $ edos-debcheck -explain -failures busybox base-files cdebconf dpkg apt libstdc++ libc6 base-passwd initscripts login module-init-tools passwd sysvinit sysv-rc libgcc1 libpopt0 < ~/.dpkg-cross/unstable/lists/www.emdebian.org_emdebian_dists_unstable_main_binary-arm_Packages | grep depends This gives: apt (= 0.6.46.4em1) depends on libapt-inst--6-1.1 {NOT AVAILABLE} base-files (= 4em1) depends on awk {mawk (= 1.3.3-11em1)} base-passwd (= 3.5.11em1) depends on libgcc1 (>= 1:4.1.1-12) {NOT AVAILABLE} busybox (= 1:1.1.3-4em1) depends on libgcc1 (>= 1:4.1.1-12) {NOT AVAILABLE} cdebconf (= 0.115em1) depends on libc6 (>= 2.5) {NOT AVAILABLE} dpkg (= 1.13.25em1) depends on libc6 (>= 2.5) {NOT AVAILABLE} initscripts (= 2.86.ds1-38em1) depends on libc6 (>= 2.5) {NOT AVAILABLE} libpopt0 (= 1.10-3em1) depends on libgcc1 (>= 1:4.1.1-12) {NOT AVAILABLE} login (= 1:4.0.18.1-7em1) depends on libpam-modules (>= 0.72-5) {NOT AVAILABLE} module-init-tools (= 3.3-pre4-2em1) depends on libc6 (>= 2.5) {NOT AVAILABLE} passwd (= 1:4.0.18.1-7em1) depends on libc6 (>= 2.5) {NOT AVAILABLE} sysvinit (= 2.86.ds1-38em1) depends on libc6 (>= 2.5) {NOT AVAILABLE} That kind of information will gradually migrate into a webpage similar to the toolchain status pages [2] which themselves will be getting edos-debcheck output in due course. So, libc6 needs a refresh, the apt build appears to be broken, we need libgcc1 cross-built from gcc-4.1 (which gets confusing when gcc-4.1 is itself part of the cross-building toolchain) and pam needs a fix [2a]. Not sure what the fix is for base-files, I suspect it may simply be a changed dependency in debian/control. Not to mention that this rootfs hasn't been tested and there may well be problems hidden in the as yet unexecuted binaries. Underlying these issues are a few bugs in emdebian-tools, specifically when updating from an existing emdebian build to an updated Debian revision. Please feel free to report these to the Debian BTS, especially if you have a patch. Check the TODO in emdebian-tools SVN for notes on other problems. [2b] This is an area that I knew was not complete but it's hard to test when there were no packages that could be updated. ;-) Anyone fancy helping with gcc-4.1 and libc6? The main problem with libc6 is size - the current emdebian package (2.3.6.ds1-9em1) has a size of: 9.08Mb download, 26.20Mb installed [3]. That compares to the Debian version (2.3.6.ds1-13) {testing} which has a size of: 3755.8kb download 8960kb installed [4]. Ouch! I'm sure it's a stripping issue but I can't find where it is going wrong. The apt-breakage is also related to libc6 - the cross-build is not identifying a libc6 version string correctly when generating the package name for what should be: libapt-pkg-libc6.3-6-3.11 or similar. If there are bugs in the Debian packages that complicate or prevent cross-building, please report those in the Debian BTS too - so far I've had good success with such bug reports. The rootfs is my main priority until DebConf and emdebian-tools (and possibly apt-cross) will need fixes to get a usable rootfs that can be updated as the Debian packages update. Other bugs (like the cdrom/no internet access problem) will take a bit of a back seat whilst this is going on. The best way to improve the emdebian-tools documentation, the Emdebian website and the contents of the Wiki is for more people to use the tools to build a rootfs and the basic packages for GPE, then raise wishlist bugs with ideas on what is missing from the docs or create new pages or new content in the Wiki. Please also report outdated pages either on the website or the Wiki. Note that this rootfs has *no perl* dependency - perl has problems cross-building currently anyway [2a] - only dpkg-dev would require perl and that isn't part of a rootfs. cdebconf [5] takes the place of debconf. cdebconf has been built without Gtk - it may be worth seeing if cdebconf can be split to support a separate gtk frontend. There appears to be support because a gtk-udeb is available. [6] This (and the newt frontend) could then be installed after the rootfs is working to provide a nice GUI interface to 'debconf' for the user. There are lots of other packages to build for a more "expansive" rootfs but I'm concentrating on the most limited busybox one - at least until it starts to work! ;-) Also, there are packages in the Emdebian target repository that are not part of any rootfs - some of these can be updated or their missing dependencies built. Simply omit the list of packages in the above edos-debcheck command to get a full list of dependencies for the entire repository. These packages are intended to support GPE in Emdebian on ARM. I had hoped to have GPE available by DebConf but that was always ambitious. :-) [0] http://wiki.debian.org/EmdebianRootfs [1] http://packages.debian.org/testing/devel/edos-debcheck [2] http://www.emdebian.org/toolchains/unstable.html [3] http://www.emdebian.org/packages/search.php?arch=arm&distro=unstable&package=libc6 [4] http://packages.debian.org/testing/libs/libc6 [5] http://www.emdebian.org/packages/search.php?arch=arm&distro=unstable&package=cdebconf [6] http://packages.debian.org/testing/debian-installer/cdebconf-gtk-udeb [2a] http://wiki.debian.org/EmdebianGuide [2b] http://buildd.emdebian.org/svn/browser/current/host/trunk/emdebian-tools/trunk/TODO -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
