我尝试构建SESHAT（手写数学表达式解析器）。而且我在下面遇到了这样的错误：
In file included from rnnlib4seshat/DataSequence.hpp:26:0,
from symrec.h:30,
from production.h:28,
from hypothesis.h:30,
from cellcyk.h:24,
from tablecyk.h:26,
from sample.h:27,
from symfeatures.h:32,
from symfeatures.cc:18:
rnnlib4seshat/Helpers.hpp:131:15: error: reference to ‘tuple’ is ambiguous
typedef const tuple<real_t&, real_t&, real_t&, real_t&>& TDDDD;
^~~~~
我在C编程方面没有太多经验。请帮助我解决此问题。
更新：这是Helpers.hpp文件的一部分

我发现类似的问题已提交到该项目的“问题”标签（https://github.com/falvaro/seshat/issues/16）。但这没有答案。看来作者不再维护这个项目了。所以我实际上需要您的帮助。非常感谢您，我的英语不好。
