gcc 4.4.x or later. This can be installed with:
sudo zypper install gcc-c++
CMake 2.6 or higher that could be installed with:

Install 3rd parties

ViSP is interfaced with several 3rd party libraries. The complete list is provided here.

Recommended 3rd parties

We recommend to install the following:

OpenCV
sudo zypper install opencv-devel
libX11 to be able to open a window to display images
sudo zypper install libX11-devel
lapack to benefit from optimized mathematical capabilities
sudo zypper install lapack-devel
libv4l to grab images from usb or analogic cameras
sudo zypper install libv4l-devel
libxml2 to be able to configure the model-based trackers from xml files
sudo zypper install libxml2-devel

Other optional 3rd parties

We give also the way to install other 3rd party libraries to enable specific capabilities.

libjpeg and libpng to support jpeg and png images (only useful if OpenCV is not installed)
sudo zypper install libjpeg8-devel libpng-devel

Install ViSP from source code

Getting ViSP source code

There are different ways to get ViSP source code:

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

or
unzip visp-x.y.z.zip
You can also download a daily snapshot. Once downloaded, uncompress the file using
tar xvzf visp-snapshot-yyyy-mm-dd.tar.gz
Or you get the cutting-edge ViSP from GitHub repository using the following command
$ git clone https://github.com/lagadic/visp.git

We suppose now that ViSP source is in a directory denoted <source_dir>, for example $HOME/visp

Configuring ViSP from source

Create first a directory denoted <binary_dir> where you want to build ViSP. This directory will contain generated Makefiles, object files, and output libraries and binaries.
cd $HOME; mkdir visp-build
Enter the <binary_dir> and configure the build:
cd $HOME/Vvisp-build

cmake ../visp

A more versatile way to configure the build is to use ccmake, the CMake GUI:
ccmake ../visp

The following image shows that this command allows to configure (just by pressing [c] key) the build in a more advanced way where some options could be easily turned On/Off. It allows also to see which are the 3rd parties that will be used. To generate the makefiles, just press [g] key in the ccmake gui.

Snapshot of the ccmake ../visp command used to configure ViSP.

Building ViSP from source

To build ViSP proceed with:
make -j4
To install ViSP proceed with:
sudo make install
To build ViSP documentation, you have first to install Doxygen package:
sudo zypper install doxygen graphviz

Then you can proceed with:
make -j4 visp_doc

Install ViSP dataset

Some ViSP examples and tests require data (images, video, models) that are not part of ViSP source code but available in a separate archive named ViSP-images-x.y.z.zip. This archive could be downloaded from http://visp.inria.fr/download page. We provide here after the way to install these data if you want to run ViSP examples.

cd $HOME

unzip ViSP-images-x.y.z.zip

We suppose now that the data are located in $HOME/ViSP-images.

$ ls $HOME/ViSP-images
Klimt        README.md    circle  ellipse    iv    mbt   mire-2
LICENSE.txt  calibration  cube    ellipse-1  line  mire  video

Set VISP_INPUT_IMAGE_PATH environment variable to help ViSP examples and tests to find the location of the data set. It's convenient if the environment variables is automatically added to your bash session every time a new shell is launched:

echo "export VISP_INPUT_IMAGE_PATH=$HOME" >> ~/.bashrc

source ~/.bashrc

Note: For historical reasons VISP_INPUT_IMAGE_PATH should not contain the folder ViSP-images, but the parent folder.

From now, you can try to run ViSP examples and tests. For example you can run displayX example that should open a windows with Klimt painting image and some overlay drawings:

$ cd $HOME/visp-build
$ ./example/device/display/displayX
A click to close the windows...
A click to display a cross...
Cross position: 201, 441
A click to exit the program...
Bye

Tips and tricks

How to uninstall ViSP

After ViSP installation, you can remove installed material using:

$ sudo make uninstall

How to build only ViSP libraries

If you want to build only ViSP modules libraries, nor the examples, tutorials and tests:

$ make -j4 visp_modules

How to build a ViSP specific module

If you want to build a given module and all the dependencies:

$ make -j4 visp_<module_name>

For example to build the model-based tracker module named mbt, run:

$ make -j4 visp_mbt

Which are the targets that could be run with make ?

To know which are the target available with make:

$ make help | grep visp
... visp_tests
... visp_demos
... visp_tutorials
... visp_examples
... visp_modules
... visp_doc
... visp_core
... visp_detection
... visp_robot
... visp_sensor
... visp_vision
... visp_vs
... visp_ar
... visp_mbt
... visp_tt
... visp_tt_mi

Which are the 3rd party libraries that are used in ViSP ?

To see which are the optional 3rd parties that are found during the configuration stage and that will be used by ViSP during the build you can have a look to the text file named ViSP-third-party.txt and located in <binary_dir>. We provide hereafter an example of a possible content of this file:

Known issues

libjpeg.so.8 may conflict with libjpeg.so.62

Note that with openSUSE 12.04 but also with 13.02, libjpeg-devel package lead to libjpeg62.so installation, that may conflict with libjpeg8.so that is also installed. That's why we recommend to not install libjpeg-devel, but rather install libjpeg8-devel.

Linking CXX executable HelloWorld

/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: warning: libjpeg.so.8, needed by /usr/lib64/libopencv_highgui.so.2.4.9, may conflict with libjpeg.so.62
