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

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

C++

#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;
}

Error Message:

Solution 1

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

Thanks for the reply, I tried creating a string object as follows

string str = “Create Object";

string tempStr(str);

changed the print statement as

cout << gettext(tempStr) <<endl;

but Xcode(Mac IDE) says “ No matching function for gettext”

it seems as syntax error.

Solution 2

The problem is solved now after including “gettext.h”.
