cuDNN linking trouble

[Philip H]

Hey guys,

I have installed CUDA 7.0 and it's working (according to nvidia-smi and deviceQuery).

Then, I downloaded cuDNN (cudnn-6.5-linux-R1 to be precise) to a local directory and added the following to my ~.bashrc:

export LD_INCLUDE_PATH=$LD_INCLUDE_PATH:/usr/wiss/haeusser/libs/cudnn-6.5-linux-R1

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/wiss/haeusser/libs/cudnn-6.5-linux-R1

export PATH=/usr/wiss/haeusser/libs/cudnn-6.5-linux-R1:$PATH

In the Makefile.config I added

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/wiss/haeusser/libs/cudnn-6.5-linux-R1

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/wiss/haeusser/libs/cudnn-6.5-linux-R1

Still, when I run make all I get

To me, it looks like cuDNN can't be found sowhow or there's a mismatch of versions ...

Does anyone have a hint for me?

Thank you!

Philip

Okay, I solved the problem. For some reason it was a bad idea to put the links to the .bashrc. In case anyone has the same problem, just comment that reference out and you should be fine for compiling :-)

[yuangd]

"just comment that reference out" , would you please tell me how to do in details? thank you

[Philip Häusser | PH1L.tv]

Just make sure that for compiling, you reference cudnn in the Makefile.config (as described) but you don't have any links in your .bashrc. If you've never changed your .bashrc you should be fine.

I have the same issue while trying to build the latest version of caffe ( I have built a previous one in the past) and that does not work and I do not understand why it would in the first place.
