Hi,

When I run make to build Caffe2, I got the error as following. (Environmemnt : Ubuntu 14.04, CUDA 8.0, CUDNN 5.1) Any suggestion would be helpful. Thanks.

Same issue here, has anyone solved it ?

Any updates on this issue? I am also facing the exact same problem.

I meet the issue, the caffe2 link to my system eigen instead of the one in third-party. It is same as the following: https://github.com/caffe2/caffe2/issues/1311
