由于没有libnvidia编码，因此正在运行NVENC sdk示例会出错 [英] running NVENC sdk sample get error because there is not libnvidia-encode
问题描述
当我要在centos 6.4上制作nvEncodeApp NVENC SDK示例时，出现此错误:
when I want to make nvEncodeApp NVENC SDK sample on centos 6.4 I got this error :
/usr/bin/ld: cannot find -lnvidia-encode
当我选中Make file时，此库的路径在这里:
when I checked Make file the path to this library was here :
-L/usr/lib64 -lnvidia-encode -ldl
我检查了/usr/lib64，但是那里没有任何libnvidia编码:
I checked /usr/lib64 but there is not any libnvidia-encode there:
该库将如何添加到该路径，这是什么库?
how this library will add to this path ,whats this library ?
使用nvidia-smi应该告诉您:
Using nvidia-smi should tell you that:

推荐答案
SDK中的自述文件表明需要R319或更高版本的驱动程序.如nvidia-smi所示，您的304.54驱动程序已经使用了将近一年，并且不符合要求.请在此处然后重试.
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.
