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。
