本文介绍了在Ubuntu 12.04 32位环境下编译Android 4.0.3包时遇到的_FORTIFY_SOURCE编译错误，并提供了详细的解决方案。通过修改源码目录下的HOST_linux-x86.mk文件，将HOST_GLOBAL_CFLAGS设置为HOST_GLOBAL_CFLAGS+=-U_FORTIFY_SOURCE-D_FORTIFY_SOURCE=0，可以解决该错误。

这两天在ubuntu12.04 32位上编译android4.0.3包，发现的如标题的错误。

错误打印如下：

host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp
<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
<built-in>:0:0: note: this is the location of the previous definition
cc1plus: all warnings being treated as errors
make: *** [out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/Main.o] Error 1

上网查了查，解决方法如下：

修改源码目录下/build/core/combo/HOST_linux-x86.mk文件：

将以下语句

HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0

修改为

HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0

ATTENTION:
There is a SPACE between the -U_FORTIFY_SOURCE and -D_FORTIFY_SOURCE
