Install and Configure OpenCV in Code Blocks

First install dependency packages

Install Code Blocks IDE

sudo apt-get install codeblocks

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

Optional packages

sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

Clone the latest OpenCV from github

git clone https://github.com/opencv/opencv.git

Compile and Install

cd ~/opencv
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make

For using with QT and OpenGL and for sample code snippets use this cmake

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 ..

 

sudo make install

Now open CodeBlocks.Now go to settings –>compiler
Under the compiler settings tab select the other options tab and copy the following command into the pane.

`pkg-config opencv --cflags`

Now open the Linker Settings Tab and copy the following command int the other linker options pane:

`pkg-config opencv --libs`

Click OK to save the settings.

Happy Hacking 🙂
