我正在尝试按照此处提供的说明在 Visual Studio 2015 RC 中松散地构建 Facebook 愚蠢： https ://github.com/jbandela/folly/tree/vc11
我希望通过 2015 年扩展的 C++11 支持，我可能会比以前更轻松。我一直在以一个不错的剪辑解决问题，但我目前遇到了一组对我来说没有意义的编译错误。这是第一个错误的编译输出的顶部：
2>------ Build started: Project: folly, Configuration: Debug Win32 ------
2> pch.cpp
2> Unknown compiler version - please run the configure tests and report the results
2>c:\program files (x86)\microsoft visual studio 14.0\vc\include\xstring(26): error C2143: syntax error: missing ',' before '<'
2>c:\program files (x86)\microsoft visual studio 14.0\vc\include\xstring(26): error C2143: syntax error: missing ',' before '<'
这是它带给我该错误位置的来源，再次在 std 命名空间的 xstring 中：
template<class _Mystr>
class _String_const_iterator
: public _Iterator012<random_access_iterator_tag, // <---- line 26
typename _Mystr::value_type,
typename _Mystr::difference_type,
typename _Mystr::const_pointer,
typename _Mystr::const_reference,
_Iterator_base>
{
我收到的另一个错误示例：
C2039 'exception': is not a member of 'std' folly c:\program files (x86)\microsoft visual studio 14.0\vc\include\stdexcept 27
来源：
class logic_error
: public _XSTD exception
{
我很困惑这些和其他 219 错误是如何与 std 库本身相关的。我通常从 Linux/g++ 构建，所以我不熟悉 Visual Studio 构建环境。我可能做一些简单的错误。像这样的错误可能是什么原因？

添加更多信息。我在没有提升的情况下复制了这个，所以“未知的编译器版本”警告消失了。我还从编译中获得了更多输出：

无论是否启用预编译头选项，都会发生这些错误。
