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
fiYou 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/libHave fun!
