本文解决了Ubuntu 11.10使用GCC4.6.1时出现的_FORTIFY_SOURCE重定义错误，通过修改HOST_linux-x86.mk文件中的配置来解决。

error: "_FORTIFY_SOURCE" redefined [-Werror]

 
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

 

此处编译错误是由于ubuntu 11.10采用了GCC4.6.1导致的。

解决方法：

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

解决方案 我认为版本3的g ++自动定义了_GNU_SOURCE。错误的第三行对此提供了支持，该错误指出第一个定义是在命令行上完成的（-D_GNU_SOURCE可见nary a ）： <command-line>: error: this is the location of the previous definition 如果您不想要它，#undef则将其作为编译单元的第一行。但是，您可能需要它，在这种情况下，请使用： #ifndef _GNU_SOURCE #define _GNU

gcc可以用' -W'开始的选项请求许多特定的警告. 反之, 每个特定的警告选项也有一个以“- wno -”开头的否定形式来关闭警告; 具体选项参见: Warning Options - Using the GNU Compiler Collection (GCC)其中, 2个选项值得注意: -w 关闭所有warning, 而 -Werror 将所有warning视为error.前者-w关闭所有warning自然需要慎用.后者-Werror有些公司项目为了引起对warning的重视, 默认开启即不允许有
