Uninstall OpenCV 3.0.0 from Ubuntu14.04

I want to use surffeature with opencv3.0.0 on Ubuntu, but I didn't install opencv_contrib at first. When I tried to install opencv_contrib, it failed. So I intend to uninstall opencv3.0.0, and reinstall it with opencv_contrib. I just delete the build file which was built during the installing opencv3.0.0. Then I type :

make uninstall

in terminal. It failed again, the error information is :

CMake Error at cmake_uninstall.cmake:20 (MESSAGE): Problem when removing "/usr/local/include/opencv2/cvconfig.h"

I found I should type :

make uninstall

instead of remove build file, but it's already done.

I installed opencv3.0.0 with the following instruction

sudo apt-get install build-essential
sudo apt-get install  git libgtk2.0-dev libavcodec-dev libavformat-dev  libtiff4-dev libswscale-dev libjasper-dev    
sudo apt-get install pkg-config   
cmake .    
mkdir build    
cd build    
cmake -D WITH_IPP=OFF ..    
make ..  
sudo make install  
cd /etc/ld.so.conf.d 
sudo /bin/bash -c 'echo "/usr/local/lib" /etc/ld.so.conf.d/opencv.conf' 

sudo ldconfig -v 

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

What should I do now ?

You have to use sudo, as the file belongs to the system and you don't have access to it by default. Try:

sudo make uninstall

It worked for me.

I delete all the opencv files, including source file and installed file under /usr/local, finally re-install opencv
