I want to integrate OpenCV with qt creator and for that OpenCV 3.0 is required.
I have OpenCV 2.4.9 already installed and want to uninstall it completely as it is causing problems in some functions. I would also like to know whether OpenCV 3.0 can be installed in 32-bit Ubuntu 14.04?
I had a similar issue, but with version 2.4.8, I found this solution:
"So, to find all OpenCV libraries 1
$> sudo find / -name "*opencv*" -exec rm -i {} \;
The above command will find any file containing opencv in the name, and will prompt you to remove it. As always, be careful when deleting things manually! That will take a hell of long time. Next I figure out that since I installed from compiling opencv from the source and used
make install
to create the install manifest, and then I pretty simple to use
make uninstall
Yes indeed it for sure clean up itself. Now I have a clean system to install the lates opencv release."
Works for me.
sudo find / -name "*opencv*" -exec rm -R {} \; worked for me to prevent prompts
This may be an easier way to go:
sudo apt-get autoremove opencv-doc opencv-data libopencv-dev libopencv2.4-java libopencv2.4-jni python-opencv libopencv-core2.4 libopencv-gpu2.4 libopencv-ts2.4 libopencv-photo2.4 libopencv-contrib2.4 libopencv-imgproc2.4 libopencv-superres2.4 libopencv-stitching2.4 libopencv-ocl2.4 libopencv-legacy2.4 libopencv-ml2.4 libopencv-video2.4 libopencv-videostab2.4 libopencv-objdetect2.4 libopencv-calib3d2.4
sudo apt-get autoremove opencv-data I tried it with opencv 2.4.9 and ubuntu 14.04 , seems it delete everything I checked it with dpkg --get-selections | grep -v deinstall | grep opencv.
Use the synaptic package manager to remove all opencv libraries from your machine.
yes | sudo find / -name "*opencv*" -exec rm -i {} \;
is the command I used if long time process is to be skipped.
Essentially it was asked in the comment and I could not repply to comment due to reputaions <50 as I am unable to login my account.
Caution: The command contains sudo and it finds all the files with name opencv and deletes it. As the process:
sudo find / -name "*opencv*" -exec rm -i {} \;
prompts for your permission for deleting any file, it takes a lot time.
yes |
just automatically inputs yes for all prompts.
Caution: Its dangerous and only recommended for those who can bear any potential file loss! It was asked, so I answered.
This worked for me:
sudo apt remove libopencv*
