c++ - 从 boost 1.38 升级到 1.39 导致我对 boost::algorithm::split 的调用无法编译

Question

我使用的是 Boost 1.38，我刚刚升级到 1.39。升级破坏了以下代码:

std::vector<std::wstring> consoleParser::loadStringsFromFile(const std::wstring &fileName)
{
    std::vector<std::wstring> files;
    std::wstring fileString(loadFileAsString(fileName));
    boost::algorithm::split(files, fileString, boost::is_any_of(L"\r\n'\"")); //Error on this line
    return files;
}

关于导致失败的原因有什么想法吗？我的编译器有用地发出以下内容:

Answer 1

您的编译失败，因为发出了一个新的警告 ( boost::detail::addr_impl_ref<T>' : assignment operator could not be generated )，并且您的设置被设置为将警告视为错误。从this来看和 this ，这确实是 Boost 1.39.0 和 VS2008 的问题。

后一个链接提供了修复该问题的补丁。它应该在 Boost 1.40.0 中得到修复。

另一种方法是暂时禁用“将警告视为错误”标志。
