I have problem when I use the cmake method to compile the caffe with the cudnn

[lji72]

ubuntu 15,4
cuda:7.0
cudnn: cudnn-linux64-6.5-v2

The problem are as follow:

cloud you tell me how to solve the problem?

Yes, the current master branch only supports cudnn v3. If you want to use cudnn v2, use an older commit.

Also, from https://github.com/BVLC/caffe/blob/master/CONTRIBUTING.md:

Please do not post usage, installation, or modeling questions, or other requests for help to Issues.
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.

Thank you.it works.

would you help me please？

I'm closing this thread since we're on a new version of cuDNN by now (v4 and soon v5).

@wqlw please try asking the mailing list for help with installation.

now my cudnn's version is v3,i am a new one .would you tell me what i do ? i shoule update the cudnn v5 or v4 please?@seanbell thanks

[seanbell]

For now, you should use v4. It will take a little while before v5 is merged in.

p.s. as of #4159 cuDNN v5 is API compatible, but we're not yet making use of its latest algorithms for further acceleration yet.
