为什么本征无法编译？

Question

我正在尝试使用Eigen + LAPACK，以便提高某些算法的性能。但是，如果我按照https://eigen.tuxfamily.org/dox/TopicUsingBlasLapack.html

的说明进行操作，则无法编译

我尝试将<boost/thread/barrier.hpp>移到文件的开头，但这不能解决问题。我的Boost库是1.68，本征是3.3.7。我从编译器传递EIGEN_USE_LAPACKE作为定义的变量。它仅与bla成功链接。我通过检查生成的代码验证了这一点。

这是第一个头文件的开头；

#define EIGEN_USE_BLAS
//#define EIGEN_USE_LAPACKE

#include <boost/thread/barrier.hpp>
#include <Eigen/Dense>

错误是：
