原来使用的ubuntu 11.10系统由于误操作，导致系统崩溃，重新安装了ubuntu 11.10；

在编译内核的时候，提示如下错误：

dingq@wd-u1110:~/hwsvn/2sw/1prj_linux/pdu/kernel/linux-2.6.30$ make menuconfig

 *** 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

解决办法：

1. 根据提示，需要安装ncurses-devel的库，但是，通过命令

sudo apt-cache search ncurses-devel  

查不到任何信息；

通过命令

sudo apt-cache search ncurses  

查到N多信息；

光是以libncurses开头的就有这么多：

libncurses-gst - Ncurses bindings for GNU Smalltalk

libncurses-ruby - Transitional package for ruby-ncurses

libncurses-ruby1.8 - Transitional package for ruby-ncurses

libncurses-ruby1.9 - Transitional package for ruby-ncurses

libncurses-ruby1.9.1 - Transitional package for ruby-ncurses

libncursesada-doc - Ada binding to the ncurses text interface library: documentation

libncursesada1 - Ada binding to the ncurses text interface library: shared library

libncursesada1-dbg - Ada binding to the ncurses text interface library: debug symbols

libncursesada1-dev - Ada binding to the ncurses text interface library: development  

2. 放狗搜一下，看到说只要安装libncurses5-dev就够了。

sudo apt-get install libncurses5-dev  

安装完毕之后再运行make menuconfig就可以了。

问题解决。
