Nvidia cudnn installation on Fedora 22


Download the cuDNN archive

You'll need to have an Nvidia Developer account.

Nvidia's missing instructions

Assuming your CUDA installation is in /usr/local/cuda (which points to /usr/local/cuda-7.x, which is the default way that Nvidia installs on Fedora, at least) :

# Wherever you downloaded the .tgz to :
tar --no-same-owner --owner=root --group=root -xzf cudnn-7.0-linux-x64-v3.0-prod.tgz --directory=/usr/local

# Check the new files arrived in the right place
ls -l /usr/local/cuda-7.0/lib64/libcudnn*

# Make sure your compilers find them
ldconfig -vvvv
