    text
    copied!<p>I am looking for a complete i18n <code>gettext()</code> hello world example. I have started a script based upon <a href="http://oriya.sarovar.org/docs/gettext_single.html" rel="noreferrer">A tutorial on Native Language Support using GNU gettext</a> by G. Mohanty. I am using Linux and G++.</p> <p>Code:</p> <pre><code>cat &gt;hellogt.cxx &lt;&lt;EOF // hellogt.cxx #include &lt;libintl.h&gt; #include &lt;locale.h&gt; #include &lt;iostream&gt; #include &lt;cstdlib&gt; int main (){ char* cwd = getenv("PWD"); std::cout &lt;&lt; "getenv(PWD): " &lt;&lt; (cwd?cwd:"NULL") &lt;&lt; std::endl; char* l = getenv("LANG"); std::cout &lt;&lt; "getenv(LANG): " &lt;&lt; (l?l:"NULL") &lt;&lt; std::endl; char* s = setlocale(LC_ALL, ""); std::cout &lt;&lt; "setlocale(): " &lt;&lt; (s?s:"NULL") &lt;&lt; std::endl; std::cout &lt;&lt; "bindtextdomain(): " &lt;&lt; bindtextdomain("hellogt", cwd) &lt;&lt; std::endl; std::cout &lt;&lt; "textdomain(): " &lt;&lt; textdomain( "hellogt") &lt;&lt; std::endl; std::cout &lt;&lt; gettext("hello, world!") &lt;&lt; std::endl; } EOF g++ -ohellogt hellogt.cxx xgettext -d hellogt -o hellogt.pot hellogt.cxx msginit --no-translator -l es_MX -o hellogt_spanish.po -i hellogt.pot sed --in-place hellogt_spanish.po --expression='/#: /,$ s/""/"hola mundo"/' sed --in-place hellogt_spanish.po --expression='s/PACKAGE VERSION/hellogt 1.0/' mkdir -p ./es_MX/LC_MESSAGES msgfmt -c -v -o ./es_MX/LC_MESSAGES/hellogt.mo hellogt_spanish.po export LANG=es_MX ls -l $PWD/es_MX/LC_MESSAGES/hellogt.mo ./hellogt strace -e trace=open ./hellogt </code></pre> <p>The program compiles, the text is extracted, Spanish file is created, modified and binary created but hellogt still displays English. The trace shows no evidence of looking in the current working directory for es_MX nor any references to LC_MESSAGES directory.</p>
