Hey guys, Rico Tzschichholz has arranged enabling armhf (ARM with hardware support for floating-point instructions) builds for our Daily PPA! First binary builds, starting with Granite, should start appearing in the repository in a few hours.
According to Rico, this is the first non-Canonical PPA to receive armhf support. With our daily PPA frequently showing up at https://launchpad.net/ubuntu/+ppas as one of the 5 most updated PPAs, I'm afraid we're going to put quite a strain on Launchpad's builders! Perhaps Canonical are after some load testing? :) For armhf builds to work the Daily PPA has to be self-contained from now on because dependency PPAs don't have armhf builds for architecture-dependent packages. I've just run a round of deb-packaging branch updates with a script I hacked together for the occasion (can be viewed at http://pastebin.com/cSBEA0gh) to make all packages buildable on vanilla Precise. Packages that need valac 0.16 now explicitly ask for "valac-0.16" package and fall back to "valac" package v0.16 or greater, which should allow building them properly on vanilla Precise which defaults to valac-0.14. I wonder if we still need the dependency on https://launchpad.net/~vala-team/+archive/ppa if packages build OK without it. Does using the latest vala-0.16 from nemequ's PPA benefit the x86 architectures in any way? The other external dependency - https://launchpad.net/~nemequ/+archive/sqlheavy - is required by Postler. We could copy the sqlheavy package to Daily PPA and get rid of it, thus solving the problem, but I'm not a fan of copying frozen versions of third-party stuff into the PPA. ARM builds might also expose some portability issues that our apps might have. I'm not sure what shall we do about them just now; perhaps ignoring them and focusing on releasing Luna for x86 is the best approach because we're not going to get any decent ISOs for ARM anytime soon: partial support for supporting several hardware configurations with one kernel was landed only in Linux 3.7 while on Precise we're stuck with 3.2 for ARM. Also note that Testing and Stable PPAs are not yet armhf-enabled (I'm not sure why; if you really want to know you'll have to ask Rico). -- Sergey "Shnatsel" Davidoff OS architect @ elementary -- Mailing list: https://launchpad.net/~elementary-dev-community Post to : elementary-dev-community@lists.launchpad.net Unsubscribe : https://launchpad.net/~elementary-dev-community More help : https://help.launchpad.net/ListHelp
