I'm fine tuning the build of lilypond and they (lilypond devs) recommend building the documentation, which takes a long time, using "make -jx CPU_COUNT=x doc" where x is the cpu core count +1. When building online the "%{?jobs:-j%{jobs}}" macro expands to -j 4 but not being sure of these things, when I use just plain "make -j x" on my box it doesn't speed up the documentation build much whereas if I add "-j 3 CPU_COUNT=3" the build time is reduced from one and a half hours to half an hour approximately. Is there a way of duplicating this on line?
%jobs is set to the number of parallel compile jobs to use. It's independent of the number of actual cpus as %jobs is set when iceream is used too. That CPU_COUNT thing is a special feature of your Makefile I guess. You better don't use %jobs there as icecream is of no use for building the documentation.
I'll play with the CPU_COUNT= option, is there a way of getting the jobs= number to use in the spec file, that you know of?
Another question, using the openSUSE build script, I've tried to pass the option to rpmbuild "-bi --short-circuit" via RPM_BUILD_STAGE environment option and it gets rejected as invalid either because of the other options or because of the '-bi --short-circuit' '' quotes. If I'm not making a silly mistake when executing "export RPM_BUILD_STAGE=-bi\ --short-circuit" then I'll make an enhancement request.
--short-circuit won't work anyways I guess as the build script wipes %_topdir in each run. You'd have to chroot into the buildroot and call rpmbuild yourself: # vi $BUILD_ROOT/.build.command # chroot $BUILD_ROOT su -c /.build.command - abuild

This calls for an enhancement request, as build is a good way of simulating osc build to fine tune packages, it picks up things that plain rpmbuild doesn't, in fact I can even play with the script myself and submit it. There is nothing better to debug %install and %file section problems than rpmbuild -bx --short-circuit.
