命名空间编译问题 [英] Namespace compilation issues

问题描述

我是 Visual Studio 的新手(我使用的是 2005 版).我遇到了无法弄清楚的命名空间问题.

I am new to working in Visual Studio (am using version 2005). I am running into a problem with namespaces that I am not able to figure out.

我正在尝试创建一个静态库，稍后将链接到应用程序.

I am trying to create a static library which I will link to an Application later.

所以，我有一个包含以下代码的 XXX.h 文件

So, I have a XXX.h file with the following code

#ifndef _XXX_X_H
#define _XXX_X_H

namespace LLL_NWK
{
   void lllInit();
}
#endif

我在 XXX.c 中包含了 XXX.h，代码如下

I include XXX.h in XXX.c and the code looks like

#include "XXX.h"

using namespace LLL_NWK;

void lllInit()
{
}

但是，当我构建库时遇到以下错误

However, when I build the Library I encounter the following errors

error C2061: syntax error : identifier 'LLL_NWK'
error C2059: syntax error : ';'
error C2449: found '{' at file scope (missing function header?)
error C2059: syntax error : '}'

我无法找出此错误的原因.希望得到一些帮助和指点.

I am unable to figure out the cause of this error. Would appreciate some help and pointers.

推荐答案

首先，using namespace LLL_NWK 在这里是不合适的.您正在声明和定义namespace LLL_NWK 的void lllInit() outside 函数.您需要将定义放在命名空间内，可以这样做:

First, using namespace LLL_NWK is not appropriate here. You are declaring and defining a function void lllInit() outside of namespace LLL_NWK. You need to place the definition inside of the namespace, which can be done like this:

void LLL_NWK::lllInit()
{
}

或者像这样:

namespace LLL_NWK
{
   void lllInit()
   {
   }
}

其次，确保将代码编译为 C++.
