I tried searching for any previous discussions of this class or any other rationale, but even the commit itself doesn't provide much explanation for it... Phil, Do you mind giving a short description of this peculiar rm_old_work class? :) Thanks. -- Denys > > > And I think more people have different "tmp/" part e.g. default would be > > > "tmp-eglibc/" (thanks to TCLIBCAPPEND > > > meta/conf/distro/defaultsetup.conf:TMPDIR .= "${TCLIBCAPPEND}"), but "work" is > > > quite common. > > > > > > meta/conf/bitbake.conf: > > > WORKDIR = "${TMPDIR}/work/${MULTIMACH_TARGET_SYS}/${PF}" > > > meta-shr/classes/rm_old_work.bbclass: > > > WORKDIR = "${TMPDIR}/work/${MULTIMACH_TARGET_SYS}/${PN}/${PF}" > > > meta-micro/classes/rm_old_work.bbclass: > > > WORKDIR = "${TMPDIR}/work/${MULTIMACH_TARGET_SYS}/${PN}/${EXTENDPE}${PV}-${PR}" > > > > > > Cheers, > > > > > > > > > > > >> Regards, > > > > >> Kai > > > > >> > > > > >>> If get WORKDIR in this way, I'll update the script with no argument > > > > >>> because the argument is useless to identify the WORKDIR. > > > > >>> > > > > >>> Regards, > > > > >>> Kai > > > > >>>> since you already call into bitbake in the script in question. > > > > >>>> > > > > >>>> Cheers, > > > > >>>> > > > > >>>> Richard > > > > >>>> > > > > >>>> > > > > >>> > > > > >>> _______________________________________________ > > > > >>> bitbake-devel mailing list > > > > >>> bitbake-devel@lists.openembedded.org > > > > >>> http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/bitbake-devel > > > > >> > > > > >> _______________________________________________ > > > > >> bitbake-devel mailing list > > > > >> bitbake-devel@lists.openembedded.org > > > > >> http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/bitbake-devel > > > > > > > > > > -- > > > Martin 'JaMa' Jansa jabber: Martin.Jansa@gmail.com > > > > > > > > > _______________________________________________ > > > bitbake-devel mailing list > > > bitbake-devel@lists.openembedded.org > > > http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/bitbake-devel > > > > -- > Martin 'JaMa' Jansa jabber: Martin.Jansa@gmail.com
