(python 问题解决)
(依赖安装，cmake参数)
redhat安装opencv
一、直接cmake
问题：
- make[1]: *** [modules/python/CMakeFiles/opencv_python.dir/all] Error 2
- make[2]: *** [lib/cv2.so] Error 1
- 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
- tar xvf Python-2.7.12.tgz
- cd Python-2.7.12
- ./configure –shared-static
- make
- sudo Make install
二、安装依赖包
- 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
- cd opencv2.3.1
CMake配置
- 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
- make //编译，需要较长时间
[100%] Built target opencv_visualisation
编译成功
安装
- sudo make install
配置
- 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
