ubuntu12.04 64bit 编译kernel（或者make menuconfig）源码时出现如下错误：
HOSTLD scripts/kconfig/mconf
scripts/kconfig/mconf.o: In function `show_help':
mconf.c:(.text+0x811): undefined reference to `stdscr'
scripts/kconfig/mconf.o: In function `main':

scripts/kconfig/lxdialog/checklist.o: In function `print_arrows':

安装libncurses5-dev可以解决
sudo apt-get install libncurses5-dev
ubuntu12.04 64bit 编译android源码时出现如下错误：
host Executable: cmu2nuance (out/host/linux-
x86/obj/EXECUTABLES/cmu2nuance_intermediates/cmu2nuance)
/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/adb_intermediates/adb] Error 1
make: *** Waiting for unfinished jobs....

安装libncurses5-dev:i386可以解决
sudo apt-get install libncurses5-dev:i386
==>那么就出现了一个共存性的问题：这两个程序任意时刻只能装一个，不能共存，所以编译时需注意。
如何解决这个共存性的问题呢？
解决办法如下：
安装如下指令安装：
sudo apt-get install lib32ncurses5-dev
