Redefinition of as a different kind of symbol
提问by nishantkyal
I'm creating a simple C++ header file in my xcode ios project but getting error "Redifinition of 'foo' as a different kind of symbol".
我正在我的 xcode ios 项目中创建一个简单的 C++ 头文件，但收到错误“将‘foo’重新定义为不同类型的符号”。
Here's the code
这是代码
class foo
{
public:
char* getLabel(char* params);
};

Well, the error message is pretty self-explanatory, foois already defined in the same namespace, and you are trying to re-define it.
嗯，错误消息是不言自明的，foo已经在同一个命名空间中定义了，您正在尝试重新定义它。
The part "as a different kind of symbol" suggests that the existing foois something else rather than a class definition. Changing the name will most likely solve your issue. Another way would be to put your definition of foointo another namespace. And anyway I would not recommend you to name something as fooin a realproject, no matter how small it is ;)
“作为一种不同类型的符号”部分表明存在foo是别的东西而不是类定义。更改名称很可能会解决您的问题。另一种方法是将您的定义foo放入另一个命名空间。反正我不建议你命名的东西作为foo一个真正的项目，不管它是多么小;）
