Linux内核编译的问题总结

make menuconfig显示错误“Your display is too small to run Menuconfig!

如果在终端执行 make menuconfig ,显示错误：
Your display is too small to run Menuconfig!
It must be at least 19 lines by 80 columns.
make[1]: *** [menuconfig] Error 1
make: *** [menuconfig] Error 2
表示终端窗口太小。解决办法可以是把终端窗口适当的调大（或是直接最大化）就行了

 

cc1: error: unrecognised debug output level "dwarf2"

cc1: error: unrecognised debug output level "dwarf2"

make[1]: *** [usr/initramfs_data.o] 错误 1

make: *** [usr] 错误 2

解决办法：把Makefile中的段注释掉就行

ifdef CONFIG_DEBUG_INFO

CFLAGS += -g

AFLAGS += -gdwarf2

endif

 

make uImage出错

"mkimage" command not found - U-Boot images will not be built
安装sudo apt-get install uboot-mkimage就好 

如果还提示错误，尝试sudo apt-get update,提示无法下载，说明你没联网
