用MKL语言编译Eigen3

Question

在Ubuntu1.1与我正在进行的Ubuntu16上的C++项目的集成工作中...我想包括对MKL和64位整数的支持。在实例化一个直接调用MKL的模板结构时，我在Eigen库中遇到了编译问题：

我必须从Eigen3中移除对MKL的支持吗？

任何帮助都将不胜感激。

免责声明:我曾经是一名EasyBuild开发人员。

在EasyBuild中，我们可以构建支持MKL的Eigen3，所以这应该是可行的。

我们的一位贡献者似乎已经了解到，对于eigen3，您需要将'signature_of_eigen3_matrix_library‘文件复制到您用于包含的路径中，请参阅https://github.com/hpcugent/easybuild-easyblocks/blob/master/easybuild/easyblocks/e/eigen.py
