如何修复错误：未知的类型名称'namespace' [英] how to fix error: unknown type name ‘namespace’

问题描述

#ifndef UNO_ACTION_ 
#define UNO_ACTION_
namespace Uno
{
namespace Game
{
    class Game;
}
} // namespace

namespace Uno
{
namespace Action
{
using ::Uno::Game::Game;

class Action
{
public:
    virtual bool isDisposeable() = 0;
    virtual void takeAction(Game* game) = 0;
    virtual ~Action() {}
};

}
}
#endif

在ubutun 12.04上编译这些代码，并返回错误集：

I compile these code on ubutun 12.04 and it return to set of error:

action.h:4:1: error: unknown type name ‘namespace’
action.h:4:15: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’ token
action.h:8:1: error: unknown type name ‘namespace’
action.h:8:15: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’ token

我不知道如何解决这些错误。

I don't know how to solve these errors.

推荐答案

听起来你正试图用C编译器编译你的C ++代码。尝试使用 g ++ 而不是 gcc ，并为您的文件提供C ++扩展，例如 .cpp （而不是 .c ）。

It sounds like you're trying to compile your C++ code with a C compiler. Trying using g++ instead of gcc and giving your file a C++ extension such as .cpp (rather than .c).
