Tutorial: Installation from source for iOS devices

In this tutorial you will learn how to build ViSP framework from source on OSX in order to use it for iOS developments. These steps have been tested on OSX El Capitan 10.11.45 and 10.11.6, with CMake 3.5.2, Xcode 7.3.1 and 8.0, and Python 2.7.10.

Concerning ViSP installation, we provide also other Tutorials.

Install required software

  • CMake gui 2.8 for OSX or higher that could be download at :
  • Xcode
  • Python 2.7 (not tested with Python 3)

Getting OpenCV framework (optional)

We suggest to follow these steps in order to install OpenCV framework in such a way that the resulting ViSP framework builds with OpenCV as 3rd party. This could be useful for users who want to use keypoints throw ViSP classes (vpKltOpencv, vpKeyPoint) or the model-based tracker in his hybrid version (vpMbKltTracker). If you are not interested in ViSP capabilities that use OpenCV as 3rd party, just skip this section.

  • Download OpenCV for iOS
  • Unzip the archive in a directory denoted <framework_dir>/ios. If <framework_dir> is for example the following folder ~/framework just do the following:
    $ mkdir -p ~/framework/ios
    If the download was performed with Safari, do the following
    $ mv ~/Downloads/opencv2.framework ~/framework/ios/
    or if the download was either performed with Firefox, do the following
    $ unzip ~/Downloads/ -d ~/framework/ios
  • Add opencv2.framework to iPhoneOS existing frameworks
    $ cd `xcrun --sdk iphoneos --show-sdk-platform-path`/Developer/Library/Frameworks
    $ sudo ln -s ~/framework/ios/opencv2.framework
  • Add opencv2.framework to iPhoneSimulator existing frameworks
    $ cd `xcrun --sdk iphonesimulator --show-sdk-platform-path`/Developer/Library/Frameworks
    $ sudo ln -s ~/framework/ios/opencv2.framework

Getting ViSP source code

The following steps are only working with ViSP 3.0.1 or higher.

Here the goal is to get ViSP source code in a directory denoted <framework_dir>. If <framework_dir> is for example the following folder ~/framework there are different ways to get ViSP:

  • You can get the cutting-edge ViSP from GitHub repository using the following command
    $ cd ~/framework
    $ git clone
  • You can also download a daily snapshot. Once downloaded, uncompress the file using
    $ tar xvzf visp-snapshot-yyyy-mm-dd.tar.gz -C ~/framework
  • Or you can download the latest release as a zip or a tarball. Once downloaded, uncompress the file using either
    $ tar xvzf visp-x.y.z.tar.gz -C ~/framework
    $ unzip -d ~/framework

We suppose now that ViSP source is in a directory denoted <framework_dir>.

$ ls ~/framework

Building ViSP framework

  • Enter in the <framework_dir> and check the name of he folder containing ViSP source code
    $ cd ~/framework
    $ ls
  • Build ViSP framework
    $ python visp/platforms/ios/ ios

Once build, you will have ~/framework/ios/visp3.framework that could be added to a Xcode project for iOS devices. If you follow Getting OpenCV framework (optional) you have also ~/framework/ios/opencv2.framework that should also be added to the Xcode project.

$ ls ~/framework/ios
