opencv2在centos6.5上开发

博客写的有点乱,一般都是工作中遇到的问题,做一下笔记

1) 因为之前opencv是在centos7上开发调试的.突然发现服务器是cents6.x的.只能移植

centos 直接使用

pip install pyopenssl
yum install opencv opencv-core -y
yum install gtk+-devel gtk2-devel -y
yum install python-devel -y

2) centos 6.x安装opencv2.4.9

下载 :

http://heanet.dl.sourceforge.net/project/opencvlibrary/opencv-unix/2.4.9/opencv-2.4.9.zip

解压缩到目录opencv-2.4.9,编译:

yum install cmake -y

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_NEW_PYTHON_SUPPORT=NO .

make

编译之后,可以发现 opencv-2.4.9/lib目录下有好多东西

make install

其他: 为下一步做好准备:

1.配置

新建文件 /etc/ld.so.conf.d/opencv.conf

在文件中添加  /usr/local/lib

保存之后执行配置

sudo ldconfig

2.环境变量配置

sudo vim /etc/bashrc

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

保存之后执行

source /etc/bashrc

具体可以参考: http://www.cnblogs.com/changingivan/archive/2013/01/17/2864076.html[/code] 3) 从centos7环境的/usr/include目录下,把opencv和opencv2的头文件目录拷贝至centos6.x的/usr/include目录下

可以参考:

http://blog.csdn.net/unixor/article/details/10894455

4) 因为开发的so库是提供给python的,所以需要安装python-devel.

但是python的运行环境是2.7,安装python2.7 编译.

下载:

https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz

解压缩

xz -d Python-2.7.12.tar.xz
会生成文件Python-2.7.12.tar

继续解压缩
tar xvf Python-2.7.12.tar

编译,安装(注意include文件夹下面有个Python2.7目录,如果没有,可以从centos7上复制)

./configure

make

make install

5) 编译项目源代码

g++ `pkg-config opencv --libs --cflags opencv` -fPIC -c -I/usr/include/python2.7 -I /usr/lib/python2.7/config 添加自己的cpp源代码以及h头文件

6) 测试验证

使用python脚本测试.

一切ok

备注: 编译opencv / 安装opencv / 编译python源码, / 安装python

涉及到了头文件, g++编译.

最后依赖的文件写成Makefile (有一些.a文件可能是多余的,没有去验证)

只需要在需要使用的环境,执行make,自动安装到lib64目录里面.
