I really need a faster machine, you provided the answer at this point: - make_tags_O: cd . && make -f Makefile O=/tmp/tmp.xfRz6THR6o DESTDIR=/tmp/tmp.y0nuN0Fr9n tags - make_cscope_O: cd . && make -f Makefile O=/tmp/tmp.O6phQXHU4z DESTDIR=/tmp/tmp.5mdMeF1pH2 cscope - tarpkg: ./tests/perf-targz-src-pkg . - make -C <kernelsrc> tools/perf - make -C <kernelsrc>/tools perf Almost there :-) - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
