Повысьте ошибки «назначение местоположения только для чтения» и «отсутствие функции сопоставления для вызова» (новая установка)

Я просто пробовал библиотеки Boost и столкнулся с ошибкой.

Код просто: 

#include <string>
#include <iostream>  
#include "/usr/include/boost/algorithm/string.hpp";
#include "/usr/include/boost/algorithm/string/erase.hpp";

using namespace std;
using namespace boost;
using namespace boost::algorithm;
using namespace boost::string;


int main()
{
    erase_all(" ","the quick brown fox");
    return 1;
}

Когда я его скомпилирую, я получаю массивный блок текста, в котором следующие две строки, которые я считаю полезными: 

/usr/include/boost/algorithm/string/detail/find_format_all.hpp:249: error: no matching function for call to âerase(const char [2], const char*&, const char*)â

и 

/usr/include/boost/algorithm/string/detail/replace_storage.hpp:98: error: assignment of read-only location

Я пробовал простой пример Boost с веб-сайта Boost, и он работает, но, несмотря на множество хлопот и поиска, я не могу понять, почему эта функция erase_all не будет работать. У меня такое ощущение, что это недостающее включение, но я не могу понять, какое именно.

Может кто-нибудь пролить свет на это?

Полный вывод ошибки:

Кроме того, что вы неправильно вводите входные данные в boost :: erase_all, невозможно достичь того, чего вы пытаетесь достичь.

То, что вы ввели в качестве параметров, является неизменным массивом байтовне может быть изменено с помощью Boost.

Это должно работать: 

std::string input("The quick brown fox");
boost::erase_all(input, " " );
std::cout << input << std::endl; // hopefully prints Thequickbrownfox

У вас есть аргументы транспонированные, и входная строка должна быть неконстантной.

Изменить: 

int main()
{
    erase_all(" ","the quick brown fox");
    return 1;
}

на: 

int main()
{
    char s[] = "the quick brown fox";

    erase_all(s, " ");
    return 0;
}
...
