进入内核目录，编译内核，执行make menuconfig时，提示如下：
*** Unable to find the ncurses libraries or the
*** required header files.
*** 'make menuconfig' requires the ncurses libraries.
***
*** Install ncurses (ncurses-devel) and try again.
***
scripts/kconfig/Makefile:202: recipe for target 'scripts/kconfig/dochecklxdialog' failed
make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
Makefile:520: recipe for target 'menuconfig' failed
make: *** [menuconfig] Error 2

2.. 根据错误提示解决：apt-get install ncurses-devel ，再次出现错误：
E: Unable to locate package ncurses-devel
3. 出现上面的原因是因为系统里面缺少libncurses 库，那就安装一下：sudo apt-get install libncurses-dev
4.再次make menuconfig ，成功：
