OpenCV 3.0 Trouble with Installation

I need OpenCV3.0 since it supports some new functions which I need. I used the following code for installation (I had successfully installed OpenCV 2.4.9 using this code. But for OpenCV 3.0, while doing the cmake section, some error pops up due to mismatch of MD5 checksum)

mkdir OpenCV
cd OpenCV
echo "Removing any pre-installed ffmpeg and x264"
sudo apt-get -qq remove ffmpeg x264 libx264-dev
echo "Installing Dependenices"
sudo apt-get -qq install libopencv-dev build-essential checkinstall cmake pkg-config yasm libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils ffmpeg
echo "Installing OpenCV" $version
unzip OpenCV-3.0.zip #i manually installed opencv3.0 zipfile for linux from https://github.com/Itseez/opencv/archive/3.0.0-alpha.zip
cd opencv-3.0.0-alpha
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
make -j2
sudo checkinstall
sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
echo "OpenCV 3.0 ready to be used"

When I execute the cmake command, I encounter errors. The output is shown below:

-- Configuring incomplete, errors occurred!

Why are the checksums different? Is it because OpenCV3.0 needs another version of ippicv? I understand that the error comes while downloading ippicv_linux_20140513.tgz (in the 3rd party, ippicv folder).

Can someone help me out here? Any help would be appreciated!

PS. I want to use OpenCV3.0 with Python. OpenCV2.4.9 was working well until I tried to remove it. I actually deleted every file with the name "opencv" from my system. I didn't know how to uninstall it the proper way.

To install OpenCV 3.2.0 on Ubuntu 16.04:

Required Packages:

$ sudo apt-get install build-essential
$ sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
$ sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

Download OpenCV:

$ sudo apt-get install wget
$ wget -O opencv-3.2.0.tar.gz https://github.com/opencv/opencv/archive/3.2.0.tar.gz
$ wget -O ippicv_linux_20151201.tgz https://raw.githubusercontent.com/opencv/opencv_3rdparty/81a676001ca8075ada498583e4166079e5744668/ippicv/ippicv_linux_20151201.tgz

Install OpenCV:

$ sudo apt-get install tar
$ tar xf opencv-3.2.0.tar.gz
$ mkdir -p opencv-3.2.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e
$ cp ippicv_linux_20151201.tgz opencv-3.2.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/ippicv_linux_20151201.tgz
$ cd opencv-3.2.0
$ mkdir build
$ cd build
$ cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
$ make -j7
$ sudo make install

Just follow the following procedure for Ubuntu 14.04

STEP 1 :-

To install the dependencies required for OpenCV, just run the following command:

sudo apt-get -y install libopencv-dev build-essential cmake git libgtk2.0-dev pkg-config python-dev python-numpy libdc1394-22 libdc1394-22-dev libjpeg-dev libpng12-dev libtiff4-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev libtbb-dev libqt4-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils unzip

STEP 2 :-

Download the latest version of OpenCV

wget https://github.com/Itseez/opencv/archive/3.0.0-alpha.zip
unzip opencv-3.0.0-alpha.zip

STEP 3:-

Install Open CV

cd opencv-3.0.0-alpha
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

Note : If you get the hash mismatch error, then download the file ippicv_linux_20140513.tgz manually from sourceforge

After downloading the file extract the contents to the ippicv folder in the opencv-3.0.0-alpha folder.

Now add the option -D WITH_IPP=OFF to the before cmake command.

Then execute the following commands :

make -j $(nproc)
sudo make install

STEP 4:-

Finishing installation

Now some final touches :

sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig

After the complete process execute

sudo apt-get update

and then reboot your system.

Now you have a working installation of OpenCV.

Follow the steps...

First Remove openjdk

sudo apt-get autoremove openjdk-*-jre

and install new jdk with following commands

sudo rm /var/lib/dpkg/info/oracle-java7-installer*
sudo apt-get purge oracle-java7-installer*
sudo rm /etc/apt/sources.list.d/*java*
sudo apt-get update
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Now installing the OpenCV

1. install basic development environment

sudo apt-get install build-essential cmake pkg-config

2.install opencv dependencies. ubuntu 13.04 ships with opencv, which is close enough to pull in most of the needed dependencies.

sudo apt-get build-dep libopencv-dev

3.additional dependencies for java support

sudo apt-get install default-jdk ant

4. compile opencv

tar xzvf opencv-2.4.6.1.tar.gz

cd opencv-2.4.6.1

mkdir build; cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON ..make

sudo make install

There you go....

Simply download the problematic file yourself from here: http://sourceforge.net/projects/opencvlibrary/files/3rdparty/ippicv/

Then place that file in the folder where it would have been downloaded to:

<your opencv build>/3rdparty/ippicv/downloads/<your os and version>

notice that the "your os and version" folder name indicates the file you need to download from sourceforge.

This worked for me with OpenCV 3.1 on Ubuntu 14.04.

I guess there is a dependency problem with ippicv. You need to turn WITH_IPP and INSTALL_CREATE_DISTRIB on. Rebuild it and update the links.

cmake -DWITH_IPP=ON -DINSTALL_CREATE_DISTRIB=ON . && make -j $(nproc) && make install
