安装 cuda 8.0 后无法运行 CUDA 示例

我按照以下步骤在 ubuntu 16 上安装了 cuba8.0这里。

然后执行确认测量。之后，我运行 make 并遇到如下错误：

$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

然后我查看了系统的信息

环境

$ printenv PATH
/usr/local/cuda-8.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin:/home/cocadas/Program/android-studio/bin

$ echo $LD_LIBRARY_PATH
/usr/local/cuda-8.0/lib64:/usr/local/cuda-8.0/lib64

操作系统

$ uname -m
x86_64

$ uname -r
4.4.0-64-generic

其他的

$ lspci |grep -i nvidia

那么，我还能尝试什么？

答案1

示例的 makefile 中的 nvidia-xxx 版本号有误。请用：替换它们 sed -i "s/nvidia-367/nvidia-375/g" `grep "nvidia-367" -r ./ -l` ，然后尝试重新 make。

答案2

我使用了这篇文章中的方法：cuda-示例-构建错误。我认为你只需要替换正确的 gpu 驱动程序版本UBUNTU_PKG_NAME = "nvidia-375"，你可以在

.../NVIDIA_CUDA-8.0_Samples/3_Imaging/cudaDecodeGL/findgllib.mk 文件

答案3

根本原因是链接器找不到 libnvcuvid，并且 make 文件的驱动程序版本应为 375（如帖子中所示）。因此，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' '{}' \;

答案4

这可能只限于 9.0 版本，但最新的脚本似乎会查询您通过 dpkg 安装了哪个驱动程序。如果您安装了多个驱动程序，它似乎会 grep 第一个找到的驱动程序，这往往是较旧的版本。

我只需要通过以下方式卸载一些较旧的驱动程序（不再使用）：

# NOTE: your driver versions may vary

sudo apt-get remove nvidia-367
sudo apt-get remove nvidia-375
