Ubuntu14.04 64位+Python3.4环境下安装Opencv3.0的方法

#!/bin/bash
sudo apt-get update
sudo apt-get install python3-setuptools python3-dev -y
sudo easy_install3 pip
pip3 install numpy

sudo apt-get install build-essential -y
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev -y

cd ~
wget https://github.com/Itseez/opencv/archive/3.0.0.zip #注意这里不是 cd 3.0.0  , 而是 cd opencv-3.0.0
unzip 3.0.0.zip && cd opencv-3.0.0
mkdir build && cd build

cmake -D CMAKE_BUILD_TYPE=Release \
-D CMAKE_INSTALL_PREFIX=/usr/local  \
PYTHON3_EXECUTABLE=/usr/bin/python3 \
PYTHON_INCLUDE_DIR=/usr/include/python3.4 \
PYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.4m.so \
PYTHON3_NUMPY_INCLUDE_DIRS=/usr/local/lib/python3.4/dist-packages/numpy/core/include ..

# make -j
:表示在那个一时间内进行编译的任务数 ，如果-j 后面不跟任何数字，则不限制处理器并行编译的任务数,现在发现直接用make -j4 安装会失败
#所以还是用 make -j1 成功了
make -j1
sudo make install
