Kbuild is supposed to support mixed targets. (%config and build targets) But "make all" did nothing if it was run with configuration targets. For example, $ LANG=C make defconfig all HOSTCC scripts/basic/fixdep HOSTCC scripts/kconfig/conf.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/zconf.lex.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf *** Default configuration is based on 'x86_64_defconfig' # # configuration written to .config # make: Nothing to be done for `all'. This commits allows "make %config all" and makes sure mixed targets are built one by one in the given order.
