This is cross image-creation, not cross-building. If the _cross-building_ part of this is important to punters then we don't yet have a very good answer (not everything in the developer image will crossbuild directly from the archive yet), although we are getting there as multiarch, and sbuild-with-cross-support mature. But in general most people who think they want to cross-build everything are wrong :-) In fact they really just want to cross-build a few things that they build over and over, and getting most of the system as binaries is just fine. I'm interested to hear of counter-examples (the main one being complier improvements/options which one wants to apply across the board). Another thing to note is that if the people asking for 'embedded linaro linux' want smaller images we could run our packages through the emdebian-grip tools to get smaller packages/images. (typically 2/3rds size). I'm not sure anyone has got round to trying this, not least because now everyone has SD-card based systems disk space mostly stopped being an issue. no..

Agreed Debian/Ubuntu are binary distros and there is no mileage in trying to occupy that space when other distros already do it well. But still Linaro offers Android stack that is in between or in another category... Making it relatively painless to rebuild or cross-rebuild your package-set debian-style is a useful goal, but not supporting loads of different package config options - that is something a source-based distro can do so much better. We do plan to support minimal builds for bootstrapping purposes which might be useful in this regard, but that's not really what it's for. k thanks for the clarification KA Wookey -- Principal hats: Linaro, Emdebian, Wookware, Balloonboard, ARM http://wookware.org/ ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

+++ Kalle Vahlman [2012-02-21 11:06 +0200]: 2012/2/21 Amit Kucheria amit.kuche...@linaro.org Well minimal is all I care... not buildroot. But I would expect it to be 20M in size. Does that make sense or am i speaking gibberish :-) ? Doesn't the nano flavour take care of this? Nano rootfs is 33M compressed tarball which expands to 95M. That's small, not embedded ;) quite. You can get a debian-based distro down to about 56MB uncompressed: http://www.emdebian.org/grip/index.html (using the grip bloat-removal tools), or 90Mb without (corresponds to 'nano'). To go smaller you need to scrap the upgradable-in-place aspect. In the past we made emdebian crush which around 20Mb, using a busybox base and a great deal of package modification. So it is possible to make a debian-based image this small, but it is not a sustainable thing without changes in Debian/Ubuntu to support a busybox base. Nobody is really working on this because there are so many other ways to achieve an image of this size which, frankly, make more sense.

To go smaller you need to scrap the upgradable-in-place aspect. Generally, embedded system uses NAND and JFFS2 and it can provide ~50% compression ratio which makes 90MB to be ~45MB (or 56MB to be ~28MB). These are already small. For system not using NAND but eMMC for example, a few hundred MiB is not a big deal. In both cases, leaving pkg system in rootfs may be a better idea for its benefits.

Linaro embedded Linux distro?
During ELC a few people asked me if Linaro had something bigger than nano and smaller than Ubuntu that they could use to build stuff. Of course I said Android, but a lot of people actually want a regular Linux platform where they can easily recompile what they need to hack on, add their own libs and scripts and generally work in an embedded, cross build way. I know there's OpenEmbedded and I've heard of something called livebuild. Does anyone have anymore info? This class of users is arguably the largest class of people using these boards so creating something targeted at them would allow them to get all the benefits of Linaro in a easy to use fashion. -- Zach Pfeffer Android Platform Team Lead, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

We provide 6 Ubuntu based images that we can consider as profiles. It's easy to customize or build your own image that will better fit your use case or requirements. In our case, we use live-build [1] which allow to put your customization on top of our images [2] or even from scratch. Tom has written a wiki page [3]. The page needs some update (I'm willing to help) to add upcoming armhf images and latest live-build with cross support. It is worth mentioning that you need a Debian/Ubuntu host (distribution supporting live-build). Anyway, if there's an audience for customizing Linaro Ubuntu images, we can provide tutorials.

This is cross image-creation, not cross-building. If the _cross-building_ part of this is important to punters then we don't yet have a very good answer (not everything in the developer image will crossbuild directly from the archive yet), although we are getting there as multiarch, and sbuild-with-cross-support mature. But in general most people who think they want to cross-build everything are wrong :-) In fact they really just want to cross-build a few things that they build over and over, and getting most of the system as binaries is just fine. I'm interested to hear of counter-examples (the main one being complier improvements/options which one wants to apply across the board). Another thing to note is that if the people asking for 'embedded linaro linux' want smaller images we could run our packages through the emdebian-grip tools to get smaller packages/images. (typically 2/3rds size). I'm not sure anyone has got round to trying this, not least because now everyone has SD-card based systems disk space mostly stopped being an issue. People using 'proper flash' still care. Wookey Would there be a buildroot like setup?

Debian/Ubuntu are binary distros and there is no mileage in trying to occupy that space when other distros already do it well. Making it relatively painless to rebuild or cross-rebuild your package-set debian-style is a useful goal, but not supporting loads of different package config options - that is something a source-based distro can do so much better.
