ubuntu亲测安装opencv和成功解决Makefile:160: recipe for target 'all' failed make: *** [all] Error 2

1.因为项目需要，我安装的是opencv3.0.0，从github上面下载的opencv包

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

　　git clone https://github.com/Itseez/opencv_contrib.git　　#opencv_contrib可以省略，不过安装上更全，有足够的时间的话，建议安装．

两个都下载完以后，将opencv_contrib放到opencv文件夹下面，并安装依赖项：

sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
将上面依赖性安装成功以后，进入到opencv目录下，在终端输入命令　
mkdir build；
cd build;
接下来就可以准备编译了．

cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..

　报了这样的错误Makefile:160: recipe for target 'all' failed make: *** [all] Error 2

 网上说存在一些冲突因为我电脑装了ａｎａｃｏｎｄａ，所以换条命令：

　cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_SHARED_LIBS=OFF -D WITH_OPENMP=ON -D ENABLE_PRECOMPILED_HEADERS=OFF ..

这样就成功了．．．

接下来执行make -j8或make -j4

编译完毕之后执行　sudo make install

以后步骤就完成了．仅供大家参考
