在ubuntu12.04 64位操作系统上运行32位opencv

版本说明：

OS：ubuntu12.04 64bit

Opencv：2.4.8

目标：

在ubuntu12.04 64位操作系统上运行32位opencv。

问题：

    在64位ubuntu上编译opencv得到的时64位版的。网上找了很多方法都没解决。

解决办法：

   在ubuntu12.04 32位版本上编辑opencv，然后将编译后的文件拷贝到64位ubuntu上运行。缺少的32位依赖包可以通过getlibs工具下载安装。

 

具体步骤：

1、32位ubuntu 上编译opencv

1、安装依赖包：

 

sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg62-dev libtiff4-dev cmake libswscale-dev libjasper-dev

 

 

2、然后下载openCV的源码包并解压出来，进入解压出来的目录

 

cd  ~/opencv
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..然后安装
make
sudo make install

 

 

3、安装完毕后，会在/usr/local/bin和/usr/local/lib目录下出现如下文件

 

hadoop@ubuntu32bit:/$ ll /usr/local/bin/

4、将opencv的可执行文件和库文件备份。

 

sudo mkdir opencv-2.4.8-i386
sudo mkdir opencv-2.4.8-i386/bin
sudo mkdir opencv-2.4.8-i386/lib
sudo cp /usr/local/bin/opencv* opencv-2.4.8-i386/bin
sudo cp /usr/local/lib/libopencv* opencv-2.4.8-i386/lib

 

 

 

5、将opencv-2.4.8-i386拷贝到64位ubuntu环境下。

2、64位ubuntu下部署32位软件

1、在ubuntu64位环境下安装32位兼容环境和getlibs

 

apt-get install ia32-libs getlibs

 

 

 

2、通过getlibs下载opencv依赖的32位库文件

  

sudo getlibs  -p  libavcodec-dev libavformat-dev libjpeg62-dev libtiff4-dev  libswscale-dev libjasper-dev

 

 

然后依赖的库文件加入到系统共享中

sudo vi /etc/ld.conf.

 

include /etc/ld.so.conf.d/*.conf
/usr/lib32/i386-linux-gnu/

  sudo ldconfig

3、sudo getlibs  opencv_createsamples  

 

hadoop@ubuntu05:~/bin$ sudo getlibs  opencv_createsamples

libdirac-encoder0
libgsm1
libopenjpeg2
libschroedinger-1.0-0

Continue [Y/n]? 

  

4、等在依赖的库下载完毕后，将动态库加入系统共享中

 

sudo vi /etc/ld.conf.

 

include /etc/ld.so.conf.d/*.conf
/usr/lib32/i386-linux-gnu/
/usr/lib32

 

 

sudo ldconfig

 

至此64位ubuntu 上运行32位opencv的环境依赖库安装完毕。

5、部署32位opencv

 

sudo cp opencv-2.4.8-i386/bin/* /usr/local/bin
sudo cp –r opencv-2.4.8-i386/lib /usr/local/lib/openvc

 

    sudo vi /etc/ld.so.conf 增加如下内容

/usr/local/lib/opencv  

   sudo ldconfig
