Basically, I would do: make ppc44x_defconfig make oldconfig cp .config arch/powerpc/configs/ppc44x_defconfig make distclean I did this for a number of configs. Then I went back and tried to build ppc44x_defconfig again and I got this result: [jwboyer@localhost linux-2.6]$ make ppc44x_defconfig HOSTCC scripts/basic/fixdep HOSTCC scripts/basic/docproc HOSTCC scripts/kconfig/conf.o HOSTCC scripts/kconfig/kxgettext.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/lex.zconf.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o scripts/kconfig/lex.zconf.c:1628: warning: ‘input’ defined but not used HOSTLD scripts/kconfig/conf [jwboyer@localhost linux-2.6]$ make oldconfig scripts/kconfig/conf -o arch/powerpc/Kconfig # # using defaults found in /boot/config-2.6.25.13-104.fc9.ppc64 # There was no .config file present after the initial 'make ppc44x_defconfig', so it defaulted to using something in /boot. I'm a bit baffled here, but that seems to be common to any newly updated defconfig I've done. Was there a change to Kconfig recently that won't copy the defconfig file to .config if there are no symbol changes or something like that? josh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
