Ubuntu1604+CUDA8.0+CUDNN5.1+OpenCV3.3.1+OpenCV_contrib-3.3.1 安装说明

• 下载地址

opencv3.3.1 : https://github.com/opencv/opencv/archive/3.3.1.zip

opencv_contrib-3.3.1：https://github.com/opencv/opencv_contrib/archive/3.3.1.zip

 

• 安装依赖包

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 

sudo apt-get install build-essential qt5-default ccache libv4l-dev libavresample-dev libgphoto2-dev libopenblas-base libopenblas-dev doxygen openjdk-8-jdk pylint libvtk6-dev 

sudo apt-get install pkg-config

 

• 编译

unzip opencv-3.3.1.zip
unzip opencv_contrib-3.3.1.zip

cp -r opencv_contrib-3.3.1 ./opencv-3.3.1

 由于CUDA8.0 与 OpenCV3.3.1 一直冲突，找了很多资料，但是还是没有成功解决，所以这里我选择了关闭CUDA加速。报错如下：ERROR: cuda/cuda_compile_generated_gftt.cu.o

ERROR: opencv_cudaimgproc.dir/all failed

修改：CMakeLists.txt  ， 如下图所示：

进行cmake编译以及安装：

cd build

# 这里注意 OPENCV_EXTRA_MODULES_PATH的位置为绝对位置

sudo cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/home/wdong/developmentPackage/opencv-3.3.1/opencv_contrib-3.3.1/modules/ .. 


sudo make -j64

sudo　make install

 如下图所示，显示已经安装成功：

• 链接库共享

编译安装完毕之后，为了让你的链接库被系统共享，让编译器发现，需要执行管理命令ldconfig：

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

• 配置bash

sudo gedit /etc/bash.bashrc  


＃　在末尾添加
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig  
export PKG_CONFIG_PATH 


＃　保存，执行下面命令生效
source /etc/bash.bashrc 


＃　更新
sudo updatedb

• 测试

cd samples/cpp/example_cmake/
cmake .
make
./opencv_example
