运行Cuda SDK的deviceQuery的问题

本文介绍了运行Cuda SDK的deviceQuery的问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我昨天编译了sdk例子，我也跑了很少的例子。但是今天我试图通过发出./deviceQuery命令运行deviceQuery和〜/ NVIDIA_GPU_Computing_SDK / C / bin / linux / release文件夹，它显示：

./deviceQuery：加载共享库时出错：libcudart.so.4：无法打开共享对象文件：无此类文件或目录 解决方案

设置路径：p $ p>

CUDA环境

goto / etc / $ gksudo gedit环境

在这里你可以看到PATH =/ usr / local / sbin：/ usr / local / bin：/ usr / sbin：/ usr / bin：/ sbin：/ bin：/ usr / games

这样的东西，只是追加了以下内容

：/ usr / local / cuda / bin

保存并退出编辑器

重新载入路径

环境

现在设置LD_LIBRARY_PATH：（位于/ etc /目录本身）

$ gksudo gedit ld.so.conf.d / cuda.conf

（创建一个新文件）将以下文件粘贴到文件中

/ usr / local / cuda / lib64 / usr / local / cuda / lib

save并退出编辑器 reload LD_LIBRARY_PATH

$ sudo ldconfig pre>

现在运行示例。

I compiled the sdk examples yesterday and I ran few of them also. But today I am trying to run the deviceQuery and in the ~/NVIDIA_GPU_Computing_SDK/C/bin/linux/release folder by issuing ./deviceQuery command and it is showing:

./deviceQuery: error while loading shared libraries: libcudart.so.4: cannot open shared object file: No such file or directory

Can anybody help me out please?

解决方案

Set the path environment for CUDA

goto /etc/ $ gksudo gedit environment

There you can see PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

something like that,,, just append the following

:/usr/local/cuda/bin"

save and exit the editor

reload the path

source environment

now set LD_LIBRARY_PATH: (be in /etc/ directory itself)

$ gksudo gedit ld.so.conf.d/cuda.conf

(which creates a new file) paste following into the file

/usr/local/cuda/lib64 /usr/local/cuda/lib

save and quit the editor reload LD_LIBRARY_PATH

$ sudo ldconfig

Now run the samples.
