[opensuse-buildservice] building xz requires xz
Come on, building xz requires xz ? I used to build xz on a bunch of old targets so that OTHER packages that required xz would find it, but now they all fail because the Base:build/xz I branched from changed to use xz-<version>.tar.xz as it's source file. xz itself cannot sanely buildrequires xz! (wasn't any explicit buildrequires either, just an assumption that tar would handle a .tar.xz, because the failure was only in the build logs "tar: file does not appear to be a tar archive", not a requires/buildrequires resolver message.) -- bkw -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

I maintain a project for many targets where xz and tar is only built if it's needed to let it work with xz compressed sources. You could aggregate the packages from there https://build.opensuse.org/project/monitor/home:rudi_m:bldchn
xz itself cannot sanely buildrequires xz!
You also need gcc to build gcc, or coreutils for coreutils. Of course in this case I also find it pity that xz sources were not fixed generally for all standard distros on OBS.

It depends whether tar -xf bla.tar.xz or xz -dc bla.tar.gz | tar -xf - which is AFAIR not the same on all distro. On some distros (e.g. CentOS_CentOS-5) you only need to update tar and not xz, as you see in my home:rudi_m:bldchn project. cu, Rudi -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

See https://build.opensuse.org/request/show/203465 - hope it will be accepted. Regards Michal Vyskocil

I think the difference here is that the very old gcc of the oldest distribution is still enough to start to bootstrap gcc. While xz just does not exist at all in the old distros. Yes, bootstraping is needed for many packages, but it is good when it can be avoided. -- Adrian Schroeter email: adrian@suse.de SUSE LINUX GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 21284 (AG Nürnberg) Maxfeldstraße 5 90409 Nürnberg Germany -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

The self-dependency is quite obvious: xz upstream choose to compress their tar ball with xz itself. Not sure how user friendly that is. (Good for testing, maybe.) OBS cannot unpack this, unless xz is installed.

Their idea is not to require installation of exactly 'itself', but to require any older (hopefully existing) version. I'd suggest, to recompress the xz-tarball in gz format, just like we do with the bzip2 tarball. That should help with most bootstrap issues. It might not help with a full source bootstrap, as the gzip2-tarball is then again xz compressed, thus entering a cyclic dependency. cheers, JW- -- o \ Juergen Weigert paint it green! __/ _=======.=======_ <V> | jw@suse.de back to ascii! __/ _---|____________\/ \ | 0911 74053-508 say #263A!__/ (____/ /\ (/) | _____________________________/ _/ \_ vim:set sw=2 wm=8 SUSE LINUX Products GmbH, GF: Jeff Hawn, J.Guild, F.Imendoerffer, HRB 16746 (AG Nuernberg), Maxfeldstrasse 5, 90409 Nuernberg, Germany SuSE.

Why do you claim that? Upstream does provide gzipped, bzip2ped and xzipped tarballs, so it was pure maintainer's decision to pickup xz archive. BTW: I have already submitted request for a change, which uses http://tukaani.org/xz/xz-5.0.5.tar.gz, just not yet accepted. Regards Michal Vyskocil

Thanks, My stuff is all building again. -- bkw -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org
