OpenCV multiple version on Linux ENV script of setting

来源：程序员人生发布时间：2016-07-27 09:09:28 阅读次数：2438次

I have multiple version of OpenCV, 2.4.13 and 3.1.0, on my Ubuntu 14.04.4 LTS. The developted applications depends on either one. To keep all the OpenCV versions, I wrote a script to set corresponding environment.

The body of my script is showing below:

#!/bin/bash

CV_PREFIX=/usr/local/opencv

if [ $# -eq 0 ] ; then
  echo "Usage : setcv.sh 2.4.13 or setcv.sh 3.1.0"
else
  if [ $1 != 2.4.13 -a $1 != 3.1.0 ] ; then
    echo "wrong version"
  else
    echo Setting for OpenCV-$1
    cp ${CV_PREFIX}/$1/lib/pkgconfig/opencv.pc /usr/local/lib/pkgconfig/opencv.pc
    cp ${CV_PREFIX}/OpenCV-$1.conf /etc/ld.so.conf.d/
    ldconfig
  fi
fi

You can run it with sudo

and you have to create two files: OpenCV⑵.4.13.conf and OpenCV⑶.1.0 to set the path of runtime libraries of the specified OpenCV.

For example:

/usr/local/opencv/2.4.13/lib

Have fun!
