如何跟踪C++ GNU xgettex执行？

嗨，我正在编写i18n在c + +中的示例代码。我参考了以下link。如何跟踪C++ GNU xgettex执行？

输出显示英文文本。这里有什么问题？

#include "start.hpp" 
#include <iostream> 
#include <locale.h> 
#include "/opt/local/share/gettext/gettext.h" 
using namespace std; 

int main(int argc, char *argv[]){ 

char* cwd = getenv("PWD"); 
std::cout << "getenv(PWD): " << (cwd?cwd:"NULL") << std::endl; 
char* l = getenv("LANG"); 
std::cout << "getenv(LANG): " << (l?l:"NULL") << std::endl; 
char* s = setlocale(LC_ALL, ""); 
std::cout << "setlocale(): " << (s?s:"NULL") << std::endl; 
std::cout << "bindtextdomain(): " << bindtextdomain("hello", cwd) <<   std::endl; 
std::cout << "textdomain(): " << textdomain("hello") << std::endl; 
std::cout << gettext("hello, world!") << std::endl; 

return 0;

}

$>克++ -o启动start.cpp

$> -d了xgettext开始-o start.pot start.cpp

$> msginit - no-translator -l es_MX -o start_es.po -i start.pot

创建start_es.po。

我打开使用poedit.app的start_es.po文件和翻译的文本，并保存

$>的mkdir -p ES/LC_MESSAGES

$>的msgfmt -c -v -o ./es/LC_MESSAGES/start.mo start_es.po

1已翻译的消息。

$>出口LANG = es_MX

$> ./start

有一个在代码而结合结构域的一个错误。我改变如下

std::cout << "setlocale(): " << (s ? s : "NULL") << std::endl; 
std::cout << "bindtextdomain(): " << bindtextdomain(“start", cwd)<< std::endl; 
std::cout << "textdomain(): " << textdomain(“start") << std::endl;

以下跟踪帮助我找到了。

dhcp-140:Debug UserName $ sudo dtruss -f -t open ./start 
getenv(PWD): /Users/UserName/WorkPlace/lang/DerivedData/lang/Build/Products/Debug 
getenv(LANG): NULL

bindtextdomain():
