Ubuntu 14.04 LTS (Trusty Tahr) 64 bits安装opencv3.0.0beta

获取源码

官网下载（http://opencv.org/)

gitclone
git@github.com:Itseez/opencv.git（前提是你安装了git）

解压opencv；tarzxvf ××××.tar.gz
或者 unzip×××.zip

安装相关依赖库

sudoapt-get -y install libopencv-dev build-essential cmake gitlibgtk2.0-dev pkg-config python-dev python-numpy libdc1394-22libdc1394-22-dev
libjpeg-dev libpng12-dev libtiff4-devlibjasper-dev libavcodec-dev libavformat-dev libswscale-devlibxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-devlibv4l-dev libtbb-dev libqt4-dev libfaac-dev libmp3lame-devlibopencore-amrnb-dev libopencore-amrwb-dev
libtheora-devlibvorbis-dev libxvidcore-dev x264 v4l-utils unzip

安装依赖库的时候我遇到的问题是有库不能正常安装报错如下：

libcogl15: Depends: libegl1-mesa-drivers

解决办法是采用命令：

sudoapt-get install -f

libegl1-mesa-drivers

我个人的理解是这个依赖性酷不能正常安装应该都可以采用这种方式尝试

必须保证所有的依赖库正常安装才能进行下一步的安装过程

编译opencv

cdopencv-3.0.0-beta

mkdir build

cd build

cmake -DCMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -DWITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -DWITH_QT=ON -D WITH_OPENGL=ON ..

make -j $(nproc)

sudo makeinstall

收尾

sudo/bin/bash -c 'echo "/usr/local/lib" >/etc/ld.so.conf.d/opencv.conf'

sudo ldconfig

测试

编译opencv自带历程

cdopencv/opencv-3.0.0-alpha/samples/

sudo cmake .

sudo make -j$(nproc)

cdcpp/

./cpp-example-facedetect../data/lena.jpg

./cpp-example-houghlines ../data/pic1.jpg
