完整的错误信息如下：@H_301_2@

zzh@ubuntu14:~/gem5/x86Dist/linux-2.6.28.4$ 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

然后我就根据提示安装ncurses@H_301_2@

zzh@ubuntu14:~/gem5/x86Dist/linux-2.6.28.4$ sudo apt-get install ncurses

This may mean that the package is missing,has been obsoleted,or
is only available from another source

E: Package 'ncurses' has no installation candidate

试过apt-get update、apt-get upgrade等都没有解决问题，后来搜索了一圈，是要安装下面这个，才解决问题：@H_301_2@

zzh@ubuntu14:~/gem5/x86Dist/linux-2.6.28.4$ sudo apt-get install libncurses5-dev

问题解决~~~这样就可以执行make menuconfig了@H_301_2@
