I hope to have LTS 32+64 bit packages in the repo by May or June. Some background: Sage is a large open source tree. Many upstream projects combined. Sage uses buildbot/buildslave network to build, and builds easily with one make due to strictly controlling the versions. Debianization is a hard problem due to having to separate out each component and having the right version (and sometimes customizations/patches) in Debian. The project is underway for a few years already. It was actually done in 2008 or so, but out of date almost immediately, then orphaned. It has restarted a few years later. I made a PPA to * have an easy way (in the sysadm sense) to install in the meantime * get automatic updates via apt * add a desktop icon The PPA does not really "build" sage but treats the open source upstream tree, once it is built and distributed on sagemath.org, as a binary package, i.e. simply copying the files into place in /usr/*. The buildslave network is community run, e.g. AIMS provides the 64bit 12.04 buildslave. There is no 12.04 32bit buildslave for a while now, which is why I had to discontinue that in the PPA. I hope to expand the AIMS provided buildslaves to 4: 12.04 and 14.04 both 32bit and 64 bit. Then I can "repackage in debs" those for the PPA. For non-LTS I just copy the last LTS binary into the non-LTS space, that seems to work fine. The community does provide a later non-LTS binary on sagemath.org. The rules file has no targets as everything is in the install/links files. The rules file basically says to build nothing (because it is already built). In the meantime, your 32bit12.04 LTS option is to build from source. You get no auto-updates, or desktop icon (you can easily create) but you get modular upgrades with sage -upgrade (only the components which change get downloaded and rebuilt). For example: sudo apt-get build-dep sagemath-upstream-binary cd sage-X.Y make Our delay is due to other institutional duties/academic calendar, and wanting to put the buildslaves on a 14.04 LTS server with LXC guests for the four instances. We've built a prototype to get familiar with LXC, and can get back to this after 14.04 releases. Regards, Jan References Proper fix; underway: https://wiki.debian.org/DebianScience/Sage http://people.debian.org/~thansen/debian-sage-status.html Upstream 32bit packages (only Ubuntu 13.04) http://www.mirrorservice.org/sites/www.sagemath.org/linux/32bit/index.html Those come from buildslave network, see no 12.04 32bit: http://build.sagemath.org/sage/waterfall Then I "repackage" for PPA: https://launchpad.net/~aims/+archive/sagemath Note 13.04 is end-of-life already. LTS is much more useful, and I can "copy pacages" on launchpad (the PPA platform) to the following non-LTS releases, and they seem to work fine. http://fridge.ubuntu.com/2014/01/28/ubuntu-13-04-raring-ringtail-end-of-life-reached-on-january-27-2014/ https://wiki.ubuntu.com/LTS -- .~. /V\ Jan Groenewald /( )\ www.aims.ac.za ^^-^^ -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
