ubuntu14.04+cuda7.0环境变量配置

环境：Ubuntu 14.04(台式机)+Cuda7.0

1. 判断安装环境：

The setup of CUDA development tools on a system running the appropriate version of Linux consists of a few simple steps:

• Verify the system has a CUDA-capable GPU.
• Verify the system has a supported version of Linux.
• Verify the system has gcc installed.

见官方配置手册：http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html

2. 下载镜像：

https://developer.nvidia.com/cuda-downloads

下run好了

3.关闭X server

ctr+alt+F1进入文本编辑界面

sudo /etc/init.d/lightdm stop

进入到安装目录之下(.run所在目录)

1. chmod +x cuda_7.0.28_linux.run  
2. sudo ./cuda_7.0.28_linux.run
   

一路确定,yes输过去

Driver:   Installed
    Toolkit:  Installed In /Usr/Local/Cuda-5.0
    Samples:  Installed

sudo /etc/init.d/lightdm start

ctr+alt+F7回到图形界面

8. 环境变量,Path配置：

$sudo gedit /etc/profile或~/.bashrc

1. export PATH=$PATH:/usr/local/cuda-7.0/bin  
2. export LD_LIBRARY_PATH=/usr/local/cuda-7.0/lib64:/lib  

使之生效：

source /etc/profile（对应profile）或sudo ldconfig（对应bashrc）

成功

usr/local/cuda-7.0/libnsight 下的nsight就是集成开发环境
