linux下安装opencv3.2并生成java使用库和jar

1、下载opencv压缩包：

在官方github上有各版本源码包的下载地址：https://github.com/opencv/opencv_contrib/tags

wget https://github.com/opencv/opencv/archive/3.2.0.tar.gz

2、安装相关依赖环境

yum install cmake gcc gcc-c++ gtk+-devel gimp-devel gimp-devel-tools gimp-help-browser zlib-devel libtiff-devel libjpeg-devel libpng-devel gstreamer-devel libavc1394-devel libraw1394-devel libdc1394-devel jasper-devel jasper-utils swig python libtool nasm

#安装ant环境，生成jar必须

yum install ant

3、解压opencv

tar -zxvf opencv-3.3.0.tar.gz
cd opencv-3.3.0

4、编译opencv

mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/opencv ..

5、安装

make -j7 
make install

# 生成opencv放在usr/local/opencv目录下。

[root@localhost opencv]# ls
bin include lib share

# 完成后看是否在/usr/local/opencv 中生成子文件。进入share/OpenCV/java子目录中

并查看是否存在文件：libopencv_java320.so和opencv-320.jar

[root@localhost java]# ls
libopencv_java320.so opencv-320.jar

# 存在说明opencv环境安装完成。

生成的opencv-320.jar和window下开发环境一样，使用开发环境打的包就可以。

libopencv_java320.so需要在java代码中配置加载路径。使用opencv时候，需要先加载。
