![]() ![]() Minimum required CMake version has been raised to 3.5.1. OpenCV is now C++11 library and requires C++11-compliant compiler.There have been a lot of bug fixes and other changes in these versions. You need to give an appropriate name to it as VideoSilicing.h.OpenCV released OpenCV-3.4.4 and OpenCV-4.0.0 on 20th November. To create CPP Header File, Select ( File->New->File) and select Header File.To add CPP code in Xcode, you need to follow more steps: Later on, you can use Objective-C code in Swift language via objective-c bridging header. OpenCV code will be done in CPP and you will have to make wrapper of CPP code in Objective-C. You are ready to build your OSX project now and it should be built without any issue. Type “ Library Search Path” in the Search and add /usr/local/lib path in “ Library Search Path” and set it to recursive. ![]() Now add /usr/local/include path in “ Header Search Path” and set it to recursive.ġ1- Once again you need to select the project from Xcode navigator from the left menu and go to “ Build Settings” tab. Type “ Header Search Path” in the Search. Select “ Link Binary with Libraries” and then add the OpenCV libraries that you included in the project (as in previous step).ġ0- Again select the project from Xcode navigator from the left menu and go to “ Build Settings” tab. It is recommended to group the items under some suitable name.ĩ- Now you need to select the project from Xcode navigator from the left menu and go to “ Build Phases” tab. Now select the following OpenCV libraries and press “ add” button:Ĩ- The selected OpenCV libraries will start showing in Xcode. The OpenCV libraries naming convention is as libopencv_.dylib. You need to make sure that you are including the proper library, not the shortcut file. The /usr/local/lib directory will open.ħ- Select the required OpenCV libraries and press “ Add” Button. Type/usr/local/lib and press “ Go” Button. Press ( Alt + Cmd + a) or select ( File-> Add Files to project) option from menu. Let the process finish successfully.Ħ- Now open Xcode and make a new project to add OpenCV libraries in your OSX application project. ![]() Once you enter the password and give it a go, terminal will install some dependencies from the Internet and will install some dynamic libraries in /usr/local/includeand /usr/local/lib directory on your MAC machine. It will prompt you for MAC login and password. Once the process finish, type the following command in terminal: If cmake tool is already installed on your MAC then jump to next step.Ĥ- In terminal, navigate into the OpenCV directory and type the following commands:ĥ- Now you need to wait till terminal does its processing. If it is not installed, type “ sudo port install cmake” in terminal for installing cmake tool in your MAC machine. This will be the raw code of OpenCV and you have to build it.ģ- Now you need to check if cmake is installed on your MAC machine or not by typing “ cmake” command in terminal. Following are the steps to be followed:ġ- Download latest OpenCV source code for Linux/MAC OS from this link.Ģ- Once OpenCV source code download completes, extract the OpenCV directory and save it at some location. This article covers, how OpenCV libraries are used in a Linux/MAC application. In an OSX project, we had to implement OpenCV libraries in Swift language for MAC application. ![]() OpenCV is basically an OpenSource library having the best frameworks for video processing. ![]()
