I changed one option manually in a .config file in a separate objdir requiring make oldconfig. Then I ran make (without oldconfig) and got make[4]: *** [silentoldconfig] Error 1 make[3]: *** [silentoldconfig] Error 2 make[2]: *** No rule to make target `include/config/auto.conf', needed by `include/config/kernel.release'. Stop. make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 In the past make would always run oldconfig automatically. -Andi -- ak@xxxxxxxxxxxxxxx -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
