src/caffe/layers/cudnn_relu_layer.cu(19): error: identifier "activ_desc_" is undefined

After fix cudnn5 error, this error occured, and can not figure out why? Any suggestions?

I come across the same error, did you solve the problem?

The code used a quite old version of CUDA 7. You may want to setup cuda 7 or 8 to run the code. Newer cuda version is not tested.
