不能同时包含Eigen和boost / regex

Question

我可以单独包含每个库，但是当我尝试同时包含它们时，我会遇到大量错误。我正在使用Boost v1_55_0和Eigen v3.2.1。 知道问题可能是什么吗？

我的包含如下：

#include <boost/regex.hpp>
#include <Eigen>

我粘贴下面的前几个错误，其中有超过100个错误。

Answer 1

Boost包含C ++ 11 std::array标题array，但您的包含路径正在从Eigen中获取Array标题（显然已过时）。您必须位于不区分文件的文件系统上。

似乎包含Eigen标头的正确方法是：

#include <Eigen/Eigen>

例如参见Getting Started sample。您应该修改包含路径以使用包含Eigen/头目录的目录，而不是将Eigen/目录放在包含路径上。
