Frage

when I want to make nvEncodeApp NVENC SDK sample on centos 6.4 I got this error :

/usr/bin/ld: cannot find -lnvidia-encode

when I checked Make file the path to this library was here :

-L/usr/lib64 -lnvidia-encode -ldl

I checked /usr/lib64 but there is not any libnvidia-encode there:

how this library will add to this path ,whats this library ?

Using nvidia-smi should tell you that:

Lösung 2

The readme files in the SDK indicate that an R319 or newer driver is required. Your 304.54 driver as indicated by nvidia-smi is almost a year old and does not meet the requirement. Please update to the latest linux driver for your VGX K1 GPUs here and try again.

In my case I had to create a symlink from /usr/lib/nvidia-367/ to /usr/lib/x86_64-linux-gnu/

sudo ln -sv /usr/lib/nvidia-367/libnvidia-encode.so /usr/lib/x86_64-linux-gnu/libnvidia-encode.so
