随手记3

安装g++之后，进入/NVDIA_GPU_Computing_SDK/C文件夹：

sudo make

发现报错，还要继续安装

参考下文：http://forums.nvidia.com/index.php?showtopic=171590

具体过程：

The CUDA group（This isn't necessary, but it's a good way to handle directly modifying the files in /usr/local/cuda.）

$ groupadd cuda

$ gpasswd -a <user> cuda

$ chgrp -R cuda /usr/local/cuda

$ chmod -R 775 /usr/local/cuda

where <user> is your non-root user account.（写用户名，不加尖括号）。

The .bashrc file（随手记2中修改的是/etc/profile，同理修改）：

There are a few variables needed for everything to go smoothly. These can be exported to the session (using export, but I prefer to make them permanent). Using <insert your favorite text editor here>, add the following lines to the end of the file ~/.bashrc

export PATH="/usr/local/cuda/bin:$PATH"

export LD_LIBRARY_PATH="/usr/local/cuda/lib64:/usr/local/cuda/lib:$LD_LIBRARY_PATH"

export CPLUS_INCLUDE_PATH="/usr/local/cuda/include"

export LIBRARY_PATH="/usr/lib/nvidia-current"

随手记2中已加前两行，此处加上后两行就好了。

（此处黄色高亮的部分不需要修改，依照随手记2中加上前两行就足够了，在随手记5中提到rollback此处，否则报错，费时费力，后悔。。。）

A few extra packages（安装一些很麻烦的包，sudo apt-get install ***，耐心挨个装）：

I installing found these packages were necessary to compile, however you may already have some/all of them installed.

(Fixes "cannot find -lXi" error)：

libxext-dev

libxi-dev

x11proto-xext-dev

(Fixes "cannot find -lXmu" error)：

libice-dev

libsm-dev

libxt-dev

libxmu-headers

libxmu-dev

(Fixes "cannot find -lglut" error)：

freeglut3-dev

libglut3-dev

再试一下sudo make，还是不行，报错：

/usr/bin/ld: cannot find -lGL
collect2: ld returned 1 exit status

费解了，还要继续装：
