[data base] mariadb install for python

Env:

Ubuntu 14.10
python 2.7

Commands:

import MySQLdb needs
apt-get install python2.7-mysqldb

import mysql.connector as mariadb needs
http://dev.mysql.com/downloads/connector/python/

[opencv] install

主題: opencv install

很難安裝, 筆記一下

Ubuntu 14.10

- pre install QT4

apt-get install qt4-default libqt4-dev qtchooser qt4-designer

- git clone opencv

git clone https://github.com/Itseez/opencv.git

cd opencv

mkdir release

cd release

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

sudo make

sudo make install

成功

MAC OS Yosemite 10.10.4

直接brew install opencv會有問題

- 一樣要先裝QT, 但要brew要多下"build-from-source"的option

brew install qt --build-from-source

- git clone opencv（這邊就和上面一樣)

失敗...
