c++ - 不能同时包含 Eigen 和 boost/regex

Question

我可以单独包含每个库，但是一旦我尝试同时包含它们，就会出现大量错误。我正在使用 Boost v1_55_0 和 Eigen v3.2.1。知道可能是什么问题吗？

我的包含看起来像这样:

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

我在下面粘贴了前几个错误，其中有 100 多个错误。

Boost 包括 C++11 std::array header array 但您的包含路径正在从 Eigen 中获取 Array header (显然已过时)。您必须在不区分大小写的文件系统上。

似乎包含 Eigen header 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/ header 目录的目录，而不是将 Eigen/ 目录放在包含路径上。
