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？

我的包括如下所示:

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

我正在粘贴下面的第一个错误,其中有超过100个.

Answer 1

Boost包含了C++ 11 std::array标题,array但你的include路径正在Array从Eigen中获取标题(显然是过时的).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>

请参阅" 入门"示例.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.
