Question

正如主题所说，我使用GCC 4.7.2编译我的C项目，它显示如下错误：

ext_kernel/ext_kernel.a(align.o):(.eh_frame+0x13): undefined reference to `__gcc_personality_v0'
kernel/kernel.a(os_core.o): In function `OS_TaskStatStkChk':
/mnt/G10/dcs1/newp/Heros_dev/kernel/os_core.c:1195: undefined reference to `_Unwind_Resume'
kernel/kernel.a(os_core.o): In function `OS_TCBInit':
/mnt/G10/dcs1/newp/Heros_dev/kernel/os_core.c:1352: undefined reference to `_Unwind_Resume'
kernel/kernel.a(os_core.o):(.eh_frame+0x343): undefined reference to `__gcc_personality_v0'

然后我检查并修改我的代码，我发现错误源代码如下：

void func()
{
   char str1[10];
   printf("");
}

只有当我声明一个复杂的数据类型（如数组，结构等）并调用函数时，才会发生此错误。但是当我使用gcc单独编译C文件时，不会发生此错误。我使用的gcc如下：

linux是Ubuntu 12.04。

使用gcc编译时未定义引用`_Unwind_Resume'和'__gcc_personality_v0'
