Ubuntu12.04配置NVIDIA cuda5.5經驗帖

之前配過一遍都忘光了，現在要重新配一遍真是好難過。。。特此記錄參考網站以便查閱。

=============

環境：Ubuntu 12.04+Cuda5.5

1. 判斷安裝環境：

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.

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

2. 下載鏡像：

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

下run好了

3. 安裝必要的庫

sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-devlibxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev

4. 刪除已有nvidia，拉黑名單

sudo apt-get remove --purge nvidia*sudo nano /etc/modprobe.d/blacklist.conf

blacklist.conf加入

lacklist amd76x_edacblacklist vga16fbblacklist nouveaublacklist rivafbblacklist nvidiafbblacklist rivatv

5. Ctrl+Alt+F1, 登陸後安裝

sudo service lightdm stopchmod +x cuda_5.5.22_linux_64.runsudo ./cuda_5.5.22_linux_64.run

Cuda5.5整合了toolkit，sdk和driver, 所以安裝的時候一路同意下來就好了

6. 得到以下安裝結果

    Driver:   Installed
    Toolkit:  Installed In /Usr/Local/Cuda-5.0
    Samples:  Installation Failed. Missing Required Libraries.

也就是SDK安裝失敗，這個官方手冊上也提到瞭解決方案。

7. 單獨安裝SDK

解壓sdk：

sh cuda_5.5.22_linux_64.run -extract=/path/to/extract/dir/

到根目錄下的/path/to/extract/dir/去找cuda-samples_5.5.22_*******.run, 安裝

sh cuda-samples_5.5.22_*******.run

8. Path配置：

$sudo gedit etc/profile或~/.bashrc

export PATH=$PATH:/usr/local/cuda-5.5/binexport LD_LIBRARY_PATH=/usr/local/cuda-5.5/lib64:/lib

使之生效：

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

還有一種裝sdk的方法見http://askubuntu.com/questions/338907/how-to-install-cuda-5-5-under-ubuntu-12-04-lts-64-bit

9. 驗證

見官網http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html#verify-installation

10. Cuda Hello World:

此外附上其他配置參考：

1. theano+python模組

（Ubuntu 12.04內建python不用裝，但要注意系統裡很多模組依賴python，沒事不要隨便刪！！！）

PS：CSDN新加的驗證碼功能好坑爹啊，人眼都看不清！試了6次才發出去。。。
