redhat安装opencv

一、直接cmake

问题：

1. make[1]: *** [modules/python/CMakeFiles/opencv_python.dir/all] Error 2
2. make[2]: *** [lib/cv2.so] Error 1
3. libpython2.7.a(abstract.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC

解决：

You need to reinstall python with shared and static way.

Firstly, download Python source file again.

and then..

重新安装python

1. tar xvf Python-2.7.12.tgz
2. cd Python-2.7.12
3. ./configure –shared-static
4. make
5. sudo Make install

二、安装依赖包

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

三、生成make文件并安装

1. cd opencv2.3.1

CMake配置

1. cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local -DBUILD_NEW_PYTHON_SUPPORT=NO 。

　　//这里可能提示line44错误。 进去Cmakelist.txt，把第44行注释掉

　　// 注意NO后面为空格+. 必不可少。

Build files have been written to :/****表示cmake成功

编译

1. make //编译，需要较长时间

[100%] Built target opencv_visualisation

编译成功

安装

1. sudo make install

配置

1. vim /etc/ld.so.conf.d/opencv.conf   //创建pkg-config配置文件

/usr/lib   //添加配置文件/usr/lib/pkgconfig/opencv.pc位置

或者是/usr/local/lib //位置一定要正确
