1.安装opencv:

 
a.opencv所依赖的一些包:(部分lib已安装,如需要安装通过yum install libpng,或者自行下载,相关软件放入软件包,此步骤可先省略)
yum install -y pkgconfig  libpng  zlib libjpeg  libtiff cmake
 
b.cmake安装(opencv官方建议cmake最好在cmake-2.8.x以上):
cmake-2.8.9.tar.gz
tar –zxvf cmake-2.8.9
cd cmake-2.8.9
./configure –-prefix=/usr/local/cmake
make && make install
cp -r /usr/local/cmake/bin/ /usr/bin/
 
c.下载安装:
wget http://aarnet.dl.sourceforge.net/project/opencvlibrary/opencv-unix/2.4.2/OpenCV-2.4.1.tar.bz2
tar –xvf OpenCV-2.4.1.tar.bz2
cd OpenCV-2.4.1
(确认cmake必须安装)
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/opencv .
make && make install
 
d.环境变量配置:
vim /etc/ld.so.conf
最后一行加入
/usr/local/opencv/lib/
e.复制到系统目录:
cp -r /usr/local/opencv/include/ /usr/local/include/
 
f.生效:
ldconfig
 
 
g++ `pkg-config opencv --libs --cflags opencv` drawing.c -o drawing
$ ./drawing
