It seems that I have messed things up. I forgot to install some dependencies of OpenCV on Ubuntu. To be specific, I want to install OpenCV on Ubuntu 14.04 with GUI support. I noticed that there is a package named gtk+-2.0 which is required by OpenCV. So I did
sudo apt-get install libgtk2.0-dev
or some thing like that. It installed alright. I also installed other dependencies specified here.
However, when I run cmake according to the tutorial, it says that
gtk+-2.0` not found
so OpenCV will be built without GUI support. Is there any environmental variable that I should set before I run cmake?
I can detect gtk+-2.0 by
pkg-config --modversion gtk+-2.0`
which outputs 2.24.23. Also, I remember adding some search path for gtk+-2.0, some thing like
/usr/lib/x86_64-linux-gnu/pkgconfig
Is there anything to do with this?
Thanks.

My suggestion is to clean up the build environment before continuing. make clean will not be sufficient. Remove all makefiles and start all over again.
I have just successfully installed OpenCV and ran a video file on Ubuntu 16.04 LTS. Let me know if I can be of further assistance.

I want to run Tesseract 4.0 or Tesseract 5.0 on my AWS Lambda function. So I have my docker file like so-
FROM public.ecr.aws/lambda/python:3.8
RUN mkdir app
# Copy function code
COPY / ${LAMBDA_TASK_ROOT}/app
# Install the function's dependencies using file requirements.txt
# from your project folder.
COPY requirements.txt .
RUN pip3 install -r requirements.txt --target ${LAMBDA_TASK_ROOT}
RUN rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
RUN yum -y update
RUN yum -y install tesseract
RUN yum install -y poppler-utils
# Set the CMD to your handler (could also be done as a parameter override outside of the Dockerfile)
CMD [ "app.com.emlAndMsgParser.mail_parser_test.getEmail_from_msg" ]
but when i do DockerBuild-"docker build -t qa-lambda ." on my terminal, it says Tesseract 3.0 version is getting installed. When i deploy this built Docker image to AWS Lambda,it also says Tesseract 3.0 is installed.
But I want Tesseract 4.0 or preferably Tesserct 5.0.
I tried changing the "RUN yum -y install tesseract" in my Dockerfile to "RUN yum -y install tesseract 5.0.0-alpha-320-g8dc3" and "RUN yum -y install tesseract -y" or "RUN yum -y install tesseract*".
But all of them are installing Tesseract 3.0.
Please can anyone tell me where I am going wrong?
I am a bit new to Tesseract, so any help is appreciated..thanks!
Having the same problem, I finally created a Dockerfile myself:

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
I have tried a lot of online posts to install opencv but they are not working for Ubuntu 16.04. May anyone please give me the steps to install openCV 2.4.13 on it?
There's a script I had made a while back, for installing the latest version of OpenCV (4.2 as of the last update to this answer)
Here's the link to it
https://github.com/rsnk96/Ubuntu-Setup-Scripts/blob/master/Build-OpenCV.sh
NOTE: For Ubuntu 16.10+, there are some minor dependency changes you will have to make. Have a look at the comments for the same.
Since you do not want to install opencv contrib, and you specifically want opencv 2.4.13, I have modified the script below. I would suggest you go through the script and understand what is happening before you execute it

P.S. Create a script file out of this and then just execute the script file, rather than copy-pasting it line by line into the terminal. You can do that by copying all of it, placing it in a file with the extension .sh, and then simply running that .sh file from the terminal using $ ./filename.sh
According to this source, from Ubuntu 16.04, you can now just do this to install OpenCV for Python2.7:
pip install opencv-python
or for python3:
pip3 install opencv-python
For more information, see here.
I tested this on my machine and it works, great stuff this :).
This is much easier than all other methods I have come across thus far.
sudo apt-get install build-essential cmake git pkg-config
sudo apt-get install libjpeg8-dev libtiff4-dev libjasper-dev libpng12-dev
sudo apt-get install libgtk2.0-dev
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
sudo apt-get install libatlas-base-dev gfortran
sudo apt-get install python2.7-dev
sudo pip install numpy
sudo apt-get install python-opencv
Then you can have a try:
$ python
Python 2.7.6 (default, Oct 26 2016, 20:30:19)
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv
>>> import cv2
If you have more than one opencv installation on your machine, now I tell you the most direct, effective and easy way to choose opencv version in python.
You can type the following command to check the current opencv version in python
import cv2
cv2.__version__
opencv path in python is set in system variable PYTHONPATH, you can echo this variable with echo $PYTHONPATH
If I want to use opencv3.x in python, then using vi or gedit open .bashrc in the home folder, add this content to the end
export PYTHONPATH=/home/ismart/ipa2/devel/lib/python2.7/dist-packages:/home/ismart/catkin_ws/install_isolated/lib/python2.7/dist-packages:/usr/local/opencv3.x/lib/python2.7/dist-packages

also, I used "aptitude install libopencv-dev", but it did not work. So I don't know how to finished this problem.
The packages in the official repos are outdated, don't use them. This is what I use to install OpenCV, should work for you too.

I've installed the boost libraries on Linux Mint 12 using the command sudo apt-get install libboost-dev libboost-doc, which installs the default version available in the repositories. However, the project I have to do needs the 1.44 version of boost. How do I uninstall the default (current) version 1.46 and install 1.44?
I couldn't find the documentation on the boost website to install boost from the .tar.gz package.
Boost can installed by two ways
Deb package
wget and install manually
In some case we might have installed by both type which can cause version error. Lets see how to uninstall both.
sudo apt-get update
# to uninstall deb version
sudo apt-get -y --purge remove libboost-all-dev libboost-doc libboost-dev
# to uninstall the version which we installed from source
sudo rm -f /usr/lib/libboost_*
Then we need to install other dependencies if they are not met
sudo apt-get -y install build-essential g++ python-dev autotools-dev libicu-dev libbz2-dev
Lets download the boost version which we need from the link. I am downloading the 1.54 version. Then untar and install it.
# go to home folder
cd
wget http://downloads.sourceforge.net/project/boost/boost/1.54.0/boost_1_54_0.tar.gz
tar -zxvf boost_1_54_0.tar.gz
cd boost_1_54_0
# get the no of cpucores to make faster
cpuCores=`cat /proc/cpuinfo | grep "cpu cores" | uniq | awk '{print $NF}'`
echo "Available CPU cores: "$cpuCores
./bootstrap.sh # this will generate ./b2
sudo ./b2 --with=all -j $cpuCores install
Now let's check the installed version
cat /usr/local/include/boost/version.hpp | grep "BOOST_LIB_VERSION"
You will see something like below
// BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION
#define BOOST_LIB_VERSION "1_54"
Version 1.54 of boost is installed
That's it, it worked for me. Let me know if you face any issues.
You can uninstall with
apt-get --purge remove libboost-dev libboost-doc
Download the package you need from boost website, extract and follow "getting started" instructions found inside index.html in the extracted directory.
Tested working Ubuntu 20.04 Use my script to uninstall your older version of boost in ubuntu 20.04 and follow rams instructions above
#!/bin/bash
sudo apt-get -y --purge remove libboost-all-dev libboost-doc libboost-dev
echo "clear boost dir"
sudo rm -r /usr/local/lib/libboost*
sudo rm -r /usr/local/include/boost
sudo rm -r /usr/local/lib/cmake/*
sudo rm -f /usr/lib/libboost_*
sudo rm -r /usr/include/boost
Downgrade your boost version. I'm not familiar with Mint, but assuming it is deb-based, you can do:
apt-cache show libboost-dev
to see all installable version and install a specific version with
sudo apt-get install libboost-dev=1.42.0.1
There are also convenience packages for the major boost versions:
sudo apt-get install libboost1.44-dev
As #savamane wrote you can uninstall it with
apt-get --purge remove libboost-dev libboost-doc
Another suggestion to install the .deb packages as suggested here. (Download the one fitted for your architecture though).
For still supported distros, you can simply search for the package at the distributions at http://packages.ubuntu.com/. For example libboost-system1.46.1 can be found in under the precise -> Libraries tab.
For unsupported distros, there is still a chance to find them at
http://archive.ubuntu.com/. For example can libboost-all-dev_1.40.0.1_amd64.deb be found in
http://archive.ubuntu.com/ubuntu/pool/universe/b/boost-defaults/.
This is how you install a specific Boost version:
cd boost_1_54_0/
./bootstrap.sh --with-libraries=atomic,date_time,exception,filesystem,iostreams,locale,program_options,regex,signals,system,test,thread,timer,log
sudo ./b2 install
