Boost Librairies中的编译失败(program_options)

今天我重建了我的C ++应用程序并且编译失败了。但是没有任何改变。第一个错误发生在我的类List中,它继承自std::vector(私有继承):

template<typename T> void List<T>::append(const T& value)
{
    push_back(value);
}

我必须在std::vector<T>::之前添加push_back(value);,因为编译器没有找到声明。我真的不知道它为什么会发生,但是有了g ++的更新,我现在在Arch Linux上使用C ++ 11使用g ++ v4.7.0(预发行版)。

我修复了这个问题,但现在,真正的问题是,由于Boost库program_options中存在问题,我无法编译应用程序的其余部分。我将库包含在:

#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...

谢谢!

我怀疑你被gcc 4.7中模板实例化的两阶段查找规则的变化所困扰。

如果没有源代码,我无法提供更实用的建议,但是gcc4.7 changes(C ++章节)给出了两个阶段查找的描述并建议了一些代码更正。
