Testing CUDA in Ubuntu 16.04: /usr/bin/ld: cannot find -lnvcuvid

Question

I've followed the steps of the NVIDIA CUDA Installation Guide and I've installed CUDA without warning or errors.

Problems arrive when I try to compile the samples provided in the CUDA toolkit. Citing the dedicated section in the previous guide: "You should compile them by changing to ~/NVIDIA_CUDA-8.0_Samples and typing make".

The output includes this:

/usr/bin/ld: cannot find -lnvcuvid

After reading related questions "/usr/bin/ld: cannot find -lcudart" and this on Stack Overflow, I checked whether lnvcuvid exists and apparently the file is missing.

However, I don't know where to safely get the file from so I'm stuck. For what it's worth:

• nvcc is already added in PATH.
• In usr/local I have either cuda and cuda-8.0 folders. I'm not sure if this is normal.

Solution 1

I had the same issue, my solution is the same as the one of MLguy: make a symbolic link of libnvcuvid.so in /usr/lib/.

sudo ln -s /usr/lib/nvidia-367/libnvcuvid.so /usr/lib/libnvcuvid.so
sudo ln -s /usr/lib/nvidia-367/libnvcuvid.so.1 /usr/lib/libnvcuvid.so.1

Where nvidia-367 depends on your computer setup.

To adapt the command to your computer, this command might help: find /usr/ -name 'libnvcuvid.so'

Solution 2

The answer is provided in the post #17 here. I'm copy pasting for your convenience:

A lazy fix would be to run (for cuda 8.0):

find . -type f -execdir sed -i 's/UBUNTU_PKG_NAME = "nvidia-367"/UBUNTU_PKG_NAME = "nvidia-375"/g' '{}' \;

in ~/NVIDIA_CUDA-8.0_Samples/.
