我正在寻找一个完整的i18n gettext()hello世界示例。我已经基于G. Mohanty 编写的使用GNU gettext的本机语言支持教程编写了一个脚本。我正在使用Linux和G ++。
gettext()
码:
cat >hellogt.cxx <<EOF // hellogt.cxx #include <libintl.h> #include <locale.h> #include <iostream> #include <cstdlib> int main (){ 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("hellogt", cwd) << std::endl; std::cout << "textdomain(): " << textdomain( "hellogt") << std::endl; std::cout << gettext("hello, world!") << 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
程序进行编译,提取文本,创建,修改和创建西班牙语文件,但是hellogt仍显示英语。跟踪没有显示在当前工作目录中查找es_MX的证据,也没有任何对LC_MESSAGES目录的引用。
cat >hellogt.cxx <<EOF // hellogt.cxx #include <libintl.h> #include <locale.h> #include <iostream> int main (){ setlocale(LC_ALL, ""); bindtextdomain("hellogt", "."); textdomain( "hellogt"); std::cout << gettext("hello, world!") << std::endl; } EOF g++ -o hellogt hellogt.cxx xgettext --package-name hellogt --package-version 1.2 --default-domain hellogt --output hellogt.pot hellogt.cxx msginit --no-translator --locale es_MX --output-file hellogt_spanish.po --input hellogt.pot sed --in-place hellogt_spanish.po --expression='/"hello, world!"/,/#: / s/""/"hola mundo"/' mkdir --parents ./es_MX.utf8/LC_MESSAGES msgfmt --check --verbose --output-file ./es_MX.utf8/LC_MESSAGES/hellogt.mo hellogt_spanish.po LANGUAGE=es_MX.utf8 ./hellogt
这是上面创建的文件的描述:
hellogt.cxx C++ source file hellogt Executable image hellogt.pot Extracted text from C++ source file (portable object template) hellogt_spanish.po Modified text for Spanish with translations added (using sed) es_MX.utf8/ LC_MESSAGES/ hellogt.mo Binary translated text for Spanish used at run-time
