make zImage报错
在官方给的ubuntu18交叉编译环境下，未改变任何配置，使用make zlmage后报错：forlinx@forlinx:~/workspace/allwinner/A40i/bsp/lichee/linux-3.10$ make zImage
scripts/kconfig/conf --silentoldconfig Kconfig
drivers/net/wireless/bcmdhd/Kconfig:50:warning: defaults for choice values not supported
***
*** Configuration file ".config" not found!

*** Please run some configurator (e.g. "make oldconfig" or

make: *** Error 2
make: *** No rule to make target 'include/config/auto.conf', needed by 'include/config/kernel.release'.Stop.
请大神帮忙解答一下，为什么会提示无线有问题？这块如何解决？
您出现这个问题的原因是，编译之前没有配置环境变量。另外手册中提到的编译内核的方法是
Linux 内核编译
# cd /root/workspace/allwinner/A40i/bsp/lichee/ #根据自己的环境切换
# ./build.sh -m kernel
