Hi During Ubuntu 'natty' cycle I am working on backporting armel cross compiler to 10.04 'lucid' and 10.10 'maverick' releases. I have a spec [1] for it and go though steps.
Cross compiler is built from two source packages: armel-cross-toolchain-base and gcc-4.5-armel-cross. There are two additional ones: gcc-4.4-armel-cross (may be dropped when gcc 4.6 get released) and gcc-defaults-armel-cross. For now 'natty' is using same versions as maverick but I am working [2][3][4] on updates. Next step is to get rid of update-alternatives use from packages as this is what gcc-defaults-armel-cross has to do. I have new version of this package ready [5] but it has to wait until I will drop u-a from toolchain packages (this can be tracked in bug 676454). Then next step will be providing backports for lucid and maverick releases. For now I have unsigned manually created repository for lucid [6]. Maverick has small update (in proposed) which fixes few bugs. To make backports I need first to patch all components (binutils, eglibc, gcc-4.5, linux) to have a way to build just *-source package from them (who wants libc6 upgrade in LTS?). I have patches [7][8][9][10] for it. I also need advice how to provide backported cross compiler packages. For now there are two ways: - Linaro maintainers PPA - ubuntu-backports repository First one requires less work as there is no cooperation required with Ubuntu backports team [11]. And there will be usually monthly updates as Linaro has montly releases which are taken by Ubuntu packaging (during development cycle) This week I will test lucid/maverick/natty builds of recent cross compiler and can provide packages for testing (no warranty that it works). Where do I need help: - review my gcc-4.[45]-armel-cross branches - review my patches in [7][8][9][10] - test my packages 1. https://blueprints.launchpad.net/ubuntu/+spec/other-linaro-n-cross- compilers 2. https://code.launchpad.net/~hrw/ubuntu/natty/gcc-4.4-armel-cross/1.37-for- review/+merge/41582 3. https://code.launchpad.net/~hrw/ubuntu/natty/gcc-4.5-armel-cross/1.41-for- review/+merge/41583 4. https://code.launchpad.net/~hrw/ubuntu/natty/armel-cross-toolchain- base/1.53-fixed/+merge/41577 5. https://code.launchpad.net/~hrw/ubuntu/natty/gcc-defaults-armel-cross/use- proper-symlinks/+merge/41040 676454. https://bugs.launchpad.net/ubuntu/+source/gcc-4.4-armel- cross/+bug/676454 6. https://wiki.linaro.org/WorkingGroups/ToolChain/CrossCompilerOnLucid 7. https://bugs.launchpad.net/ubuntu/+source/gcc-4.4/+bug/682650 8. https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/682648 9. https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/682646 10. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/682681 11. https://help.ubuntu.com/community/UbuntuBackports Regards, -- JID: h...@jabber.org Website: http://marcin.juszkiewicz.com.pl/ LinkedIn: http://www.linkedin.com/in/marcinjuszkiewicz _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
