Lib OpenCV 4 Deb

This repository contains CMake with CPack build project for the OpenCV 4 library. It was created to accomodate the library packaging using the debian packaging system.

Usage

Updating the Source Code

• Initialize and update the opencv submodule.

  $ git submodule init
  $ git submodule update

• Move to the opencv directory, pull the latest update, and checkout to the latest release tag.

  $ cd opencv
  $ git pull
  $ git checkout <latest-release>

• Change some variables value as follow:
  • Change the value of CPACK_DEBIAN_PACKAGE_VERSION variable to match with the source code release version.
  • Increase the value of CPACK_DEBIAN_PACKAGE_RELEASE variable if there is changes related to the debian packaging with the same source code release version. else reset it to 1.

Building the Library

• Create a build directory and move to it.

  $ mkdir build
  $ cd build

• Configure the Makefile rules with the following options.

  $ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr ..

• Build the library.

  $ make

  Note: you could speed up the build process with specifying the job count parameter using -jn where n is number of the jobs. (example: $ make -j4)

• Create debian package using cpack.

  $ cpack
