附录2：CentOS7配置OpenCV3.0.0 for Linux 64Bit
1、说明：
1、系统：CentOS 7
2、软件：opencv-3.0.0.zip
3、下载地址：codeload.github/opencv/opencv/zip/3.0.0
4、本次安装，系统采用root登录，若使用普通用户登录，请务必在进行所有终端操作之前，切换到root权限状态，但是不保证不会出错；即，每打开一次终端，先输入su root，回车后输入root密码再按回车，然后进行终端操作
5、本方法仅供参考
2、安装依赖包（重要）
终端输入：yum install cmake gcc gcc-c++ gtk+-devel gimp-devel gimp-devel-tools gimp-hel
p-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
按回车，期间会有提示是否继续，需要确认继续
注：如果不安装上述依赖包，到最后调用opencv时会出错，如下： 
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow,................... 
此时只能将编译好的opencv删除再重新编译，即将/usr/local/lib和/usr/local/include/中的有关的删除 
mv /usr/local/lib/libopencv* 
mv -fr /usr/local/include/opencv 
mv -fr /usr/local/include/opencv2 
然后再重新编译opencv.
3、安装/更新CMake
下载最新版本的cmake-3.6.文件进行编译
下载地址：/cmake/resources/software.html
将其复制到/usr/local目录下面，并在该目录中右键打开终端
终端输入：tar -zxvf cmake-3.6.按回车
rm -rf cmake-3.6.
cd cmake-3.6.0
./configure
make
make installnullsbrawl15赛季
mv cmake-3.6.0 cmake
if then的用法输入：vi /etc/profile
在尾部添加
PATH=/usr/local/cmake/bin:$PATH
export PATH
注意：不要将冒号写成分号，要不然各种命令行都不能用
输入：source /etc/profile按回车使修改生效
输入：echo $PATH按回车查看PATH值有没有添加刚刚的路径
输入：cmake -version按回车查看cmake版本
注意：cmake安装成功之后再安装opencv
socket什么意思中文翻译成4、安装OpenCV
下载opencv-3.0.0.zip，放于/usr/local/目录下，在该目录中右键打开终端
输入：unzip opencv-3.0.0.zip
cd opencv-3.0.0
isnumberfind函数的使用方法
注：此过程中可能出现错误，参考下方错误处理
make
make install
5、添加路径
打开终端，输入find / -name "opencv.pc" -type f按回车centos和ubuntu，出现如下内容
/usr/local/lib/pkgconfig/opencv.pc
/usr/local/opencv-3.0.0/unix-install/opencv.pc
继续输入：cp usr/local/opencv-3.0.0/unix-install/opencv.pc /usr/lib64/pkgconfig/按回车
6、错误处理：
placeholder onlyCmake过程中可能出现如下错误：
“CMake Warning at 3rdparty/ake:54 (message):
  ICV: Local copy of ICV package has invalid MD5 hash:
  0103b909e19ca9c6497a7ae696c16480 (expected:

处理方法：
下载文件
sourceforge/projects/opencvlibrary/files/3rdparty/ippicv/ippicv_/download
覆盖掉
/usr/local/opencv-3.0.0-beta/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b/目录下的文件即可
7、OpenCV安装到此结束
