从boost 1.38升级到1.39导致我的调用boost :: algorithm :: split不编译

Question

我使用Boost 1.38，并且我刚升级到1.39。升级打破了以下一段代码：

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; 
} 

任何想法是什么导致失败？我的编译器发出有益如下：

Answer 1

由于发出新警告（boost::detail::addr_impl_ref<T>' : assignment operator could not be generated），您的编译失败，并且您的设置被设置为将警告视为错误。从this和this来看，这确实是Boost 1.39.0和VS2008的问题。

后一个链接提供了修补问题的补丁。它应该在Boost 1.40.0中修复。

另一种方法是暂时禁用“将警告视为错误”标志。

Answer 2

如果我切换到警戒水位4和设置警告视为错误矿山打破了。 尝试更改这些设置。

Answer 3

我真的不喜欢“警告视为错误”对于这种原因，但你可以这样做：

#pragma warning (disable:4512) 

上面addressof.hpp任何#include行。
