Question

如何在linux系统centos下通过Eclipse配置opencv

Answer 1

1、安装依赖包(很重要）
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
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.
2、安装/更新CMake
为什么要安装或者更新cmake呢，下面说明所chǔ问题：
（1）下载
在OpenCV官网http://sourceforge.net/projects/opencvlibrary/files/ 下载所需版本
拷贝到/usr/local/路径之下
（2）tar -xvf OpenCV-2.4.8.tar.bz2 解压
（3）cd OpenCV-2.4.8 进入目录
（4）yum install cmake 直接从网上安装cmake

（5） cmake CMakeLists.txt
