ncurses是字符终端下屏幕控制的基本库。可能很多新开发的程序都不使用了，不过如果要编译一些老程序，还经常遇得到。

Building Android: error: “_FORTIFY_SOURCE” redefined [-Werror]If you are building an old version of android probably you’ll have this error
host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp
:0:0: error: “_FORTIFY_SOURCE” redefined [-Werror]
:0:0: note: this is the location of the previous definition
cc1plus: all warnings being treated as errors
To fix this, edit build/core/combo/HOST_linux-x86.mk and replace:
HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0
with
HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0
And that’s it.
