ubuntu装软件包

查找包

aptitude search pkgName

pkgName可以有多个（空格分隔）

ffmpeg

sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-next 
sudo apt-get update 
sudo apt-get install ffmpeg

编译安装opencv和opencv contrib 以及python接口

罗嗦版：http://www.cnblogs.com/zjutzz/p/6714490.html

mkdir -p ~/work/gitdown
cd $_
git clone https://github.com/opencv/opencv
git clone https://github.com/opencv/opencv_contrib
cd opencv
mkdir build
cd build

期间容易出现ippicv等第三方包下载不下来的情况。找到对应的.cmake文件，把下载地址拼接出来自行下载，注意替换掉md5的hash值。下载的文件放到<opencv_root>/.cache目录下，例如：

新编译出来的cv2.so位于/usr/local/opencv-git-master/lib/cv2.so

sudo apt-get remove python-opencv
sudo ln -sf /usr/local/opencv-git-master/lib/python2.7/dist-packages/cv2.so /usr/lib/python2.7

或者设定PYTHONPATH也可以

编译安装protobuf3.2

apt装的protobuf是2.5版本. pip装的protobuf是3.2版。 使用了python layer的网络，如果用tools/caffe.cpp编译出的工具build/caffe来执行网络，会报protobuf版本问题，需要protobuf-cpp的版本装3.2版

编译装protobuf3.2

卸载apt的protobub

sudo apt-get remove --purge libprotobuf-dev

如果你是ubuntu-desktop用户，那你的桌面有可能被误删。立即安装（不要重启）：

sudo apt-get install ubuntu-desktop -y
sudo apt-get install unity -y
sudo apt-get install compiz-gnome -y
sudo apt-get install libcompizconfig0 -y

静态编译protobuf（产生libprotobuf.a而不是.so文件，否则caffe编译会报错）

sudo apt-get install autoconf automake libtool curl make g++ unzip
cd ~/work/gitdown
git clone https://github.com/google/protobuf
git checkout -b 3.2.x origin/3.2.x
cd protobuf

vim configure

修改2658行和2661行，引号里面都换成"-fPIC"

./autogen.sh
./configure --disable-shared
make -j8
sudo make install

sudo ldconfig

重新编译caffe

cd ~/work/caffe-BVLC
make clean
make -j8
make pycaffe

android-studio

真机调试：需要先设定udev的规则。

exfat无法挂载？

sudo apt-get install exfat-utils

flash

sudo apt-get install flashplugin-installer
