使用gettext链接器错误进行国际化 [英] Internationalise using gettext linker error

问题描述

您好我正在尝试使用gettext字符串提取程序开始国际化。



我已经创建了如下示例代码。但它未能建立。

Hi I am trying to start with internationalisation using gettext string extractor.

I have created sample code as follows. But it failed to build.

#include "SupportLanguage.hpp"
#include <iostream>
#include <locale.h>
#define _(STRING) gettext(STRING)

#include "libintl.h"
using namespace std;
class SupportLanguage {

public:    
    int x = 0;    
    void display();
};

void SupportLanguage :: display(){
    cout << " Hello World" << endl;    
    cout<< "Welcome" <<endl;    
    cout << gettext("How are you doing ?") <<endl;
}

int main(){
 
    SupportLanguage sl ;    
    sl.display();
    return 0;
}

错误消息：

Undefined体系结构的符号x86_64：

_libintl_gettext，引用自：
Supporttextu中的gettext（char const *）

ld：symbol（ s）找不到架构x86_64

clang：错误：链接器命令失败，退出代码为1（使用-v查看调用）

这里有什么问题？



谢谢

我几乎不明白这个问题。

What is the problem here?

I hardly understand the problem.

推荐答案

你不能以这种方式使用gettext。构造一些字符串对象并将其用作输入参数。

You cant use gettext in that manner. Construct some string object and use it as input param.

包含gettext.h后问题现在解决了。

The problem is solved now after including "gettext.h".
