运行Cuda SDK的deviceQuery的问题

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 editorreload LD_LIBRARY_PATH
$ sudo ldconfig
Now run the samples.
