安装cuda 8.0后无法运行CUDA示例
我按照这里的步骤在ubuntu 16上安装了cuba8.0。
然后执行确认测量。 在那之后，我运行make并碰撞到如下的错误：
$make ... nvcc warning : The 'compute_20', 'sm_20', and 'sm_21' architectures are deprecated, and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning). /usr/bin/ld: cannot find -lnvcuvid collect2: error: ld returned 1 exit status Makefile:381: recipe for target 'cudaDecodeGL' failed make[1]: *** [cudaDecodeGL] Error 1 make[1]: Leaving directory '/home/cocadas/Workspace/NVIDIA_CUDA-8.0_Samples/3_Imaging/cudaDecodeGL' Makefile:52: recipe for target '3_Imaging/cudaDecodeGL/Makefile.ph_build' failed make: *** [3_Imaging/cudaDecodeGL/Makefile.ph_build] Error 2 然后，我检查了系统的信息

那么，我还能尝试什么呢？
样本的makefile具有错误的nvidia-xxx版本号。 替换为： sed -i "s/nvidia-367/nvidia-375/g" `grep "nvidia-367" -r ./ -l`并尝试重新制作。
我在这篇文章中使用了方法： cuda-sample-build-error 。 我想你只需要在UBUNTU_PKG_NAME = "nvidia-375"替换正确的gpu驱动程序版本，你可以在
… / NVIDIA_CUDA-8.0_Samples / 3_Imaging / cudaDecodeGL / findgllib.mk文件
根本原因是链接器找不到libnvcuvid和make文件的驱动程序版本应为375（如post所示）。 因此，请在文件夹中使用以下命令：
~/NVIDIA_CUDA-8.0_Samples/$find . -type f -execdir sed -i 's/UBUNTU_PKG_NAME = "nvidia-367"/UBUNTU_PKG_NAME = "nvidia-375"/g' '{}' \;
这可能是特定于9.0版本，但它看起来像最新的脚本查询您通过dpkg安装的驱动程序。 如果您安装了多个，它看起来像是在找到第一个找到的，这往往是旧版本。
我只需通过以下方式卸载一些较旧的驱动程序（不再使用它们）：
# NOTE: your driver versions may vary sudo apt-get remove nvidia-367 sudo apt-get remove nvidia-375
