嵌入式Linux之我行——配置内核时出现“ncurses-devel”错误

嵌入式Linux之我行，主要讲述和总结了本人在学习嵌入式linux中的每个步骤。一为总结经验，二希望能给想入门嵌入式Linux的朋友提供方便。如有错误之处，谢请指正。

通常在安装完Linux系统后，在编译kernel使用make menuconfig时，可能会出现如下错误：

*** Unable to find the ncurses libraries or the
*** required header files.
*** 'make menuconfig' requires the ncurses libraries.
***
*** Install ncurses (ncurses-devel) and try again.
***
make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error 2

出现该错误的原因是：在使用menuconfig时需要ncurses库的支持，而该库包含ncurses和ncurses-devel两个包，大部分情况ncurses包会跟随系统安装好，而ncurses-devel包根据安装系统时你的选择。可以使用命令查看他们有没有安装：

#rpm -q ncurses
#rpm -q ncurses-devel

如果安装好了会显示类似如下：
ncurses-5.6-16.20080301.fc9.i386
ncurses-devel-5.6-16.20080301.fc9.i386

如果没安装则可使用yum命令直接在线安装(注意要求联网):

[root@localhost linux-2.6.34]# yum install ncurses

安装完成后在试make menuconfig，错误排除了。

[root@localhost linux-2.6.34]# make menuconfig

OK！
