今天我重建了我的 C++ 应用程序,但编译失败了。什么都没有改变。第一个错误是在我的类List
中,它继承自std::vector
(私有继承)这里:
template<typename T> void List<T>::append(const T& value)
{
push_back(value);
}
我之前必须添加std::vector<T>::
,push_back(value);
因为编译器没有找到任何声明。我真的不知道为什么会这样,但是 g++ 有一个更新,我现在在 Arch Linux 上使用 C++11 使用 g++ v4.7.0(预发行版)。
我解决了这个问题,但现在真正的问题是,由于 Boost library 中的问题,我无法编译应用程序的其余部分program_options
。我包括图书馆:
#include <boost/config.hpp>
#include <boost/program_options/detail/config_file.hpp>
#include <boost/program_options/parsers.hpp>
错误:

与我的 List 类相同的错误......</p>
谢谢!
