Hello guys !! I want to upgrade my opencv2.4.9 to opencv3.0 because of the features of opencv 3.0 . When i am installing opencv3.0 directly then i ended up with some HASH MISMATCH error. I think it is due to i didn't uninstall previous version ! I would be thankful if you will help me in the same. Thanks !

OpenCV 3.0.0 beta is not the last version, it will be improved, IMHO it is not completed especially the features. I have just installed it like here and just added the version in the CMakeLists.txt as follows:

find_package(OpenCV 3.0.0)

After I have done the sudo make install I had all the .a and .so that I needed for OpenCV 3.0.0 (and the ones for 2.4.9, but this did not lead to errors). I vage Ubuntu 14.04 LTS

Hi thdrksdfthmn ! I followed this tutorial to install opevcv and stuck with error just before "sudo make install" .

Errors are given in this link.

maybe using sudo find / -name "opencv" then sudo rm ... or maybe using sudo apt-get remove ... or autoremove is better see this
