Ошибка при компиляции с g++ в OSX 10.9.1: неизвестное имя типа '__darwin_wctype_t' - программирование

Ошибка при компиляции с g++ в OSX 10.9.1: неизвестное имя типа '__darwin_wctype_t'

При компиляции даже базового кода (например, я присоединяю мир hello) в OSX 10.9.1 из командной строки с g++

#include <iostream>

int main() {std::cout << "Hello World";}

Я скомпилирую команду:

g++ hello.cc -o hw

Что генерирует следующие сообщения об ошибках:

Я ценю любой свет, который любой может пролить на это. Ни один из моих усердных googling ничего не сделал.

ОТВЕТЫ

Ответ 1

Не могли бы вы повторить попытку после добавления -I /usr/include как это

g++ hello.cc -o hw -I /usr/include

Я сделал тест на своем компьютере OSX 10.10.3 (Yosemite), и нашел что-то еще.

1) При компиляции с командой в моей ОС:

 g++ hello.cc -o hw

Нет сообщения об ошибке.

2) После нескольких опытов я нашел способ воспроизвести тот же самый вывод ошибки. Команда следующая:

 g++ hello.cc -o hw -I /usr/include/sys

Выход с сообщением об ошибке, подобным этому,

In file included from hello.cc:1:

typedef __darwin_wctype_t wctype_t;

3) Кроме того, вы можете найти более подробную информацию о компиляции с помощью команды:

g++ hello.cc -o hw -v

Затем вы можете проверить включенные файлы заголовков на выходе, как

Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn)

Ответ 2

У меня появилось подобное сообщение об ошибке на MacOS 10.9 с clang++ 3.9, поэтому я наткнулся на этот вопрос.

Оказывается, я забыл закрыть скобку объявления пространства имен в файле заголовка, который был включен до <iostream>. В моей настройке следующий код воспроизводит проблему:

namespace detail {
#include <iostream>

Это, очевидно, не проблема ОП, но я надеюсь, что это поможет другим.
