我们在更新CentOS或者Ubuntu的内核时，执行make menuconfig可能看如这样的错误：
*** Unable to find the ncurses libraries or the
*** required header files.
*** ‘make menuconfig’ requires the ncurses libraries.
***
*** Install ncurses (ncurses-devel) and try again.
解决办法如下：
CentOS：
yum install -y ncurses-devel
Ubuntu：
sudo apt-get install ncurses-dev
