SwisTrack/Developers/Setting up a development environment/Linux


You need the following programs and libraries:

The following libraries are optional and only necessary if you want to use the corresponding cameras:

  • Basler Pylon driver (according to the company, a Linux driver will be available soon)
  • Firewire camera driver

Installing LibrariesEdit

Ubuntu 12.04 (32 bit)Edit

Install wxWidgets:

 sudo apt-get install libwxgtk2.8-dev

Install OpenCV2:

sudo apt-get install libopencv-dev

Install OpenCV legacy packages:

sudo apt-get install libcv-dev libhighgui-dev libcvaux-dev libcv2.3 libcvaux2.3 libhighgui2.3

Checkout svn repository (opencv2 branch):

svn checkout svn://svn.code.sf.net/p/swistrack/code/branches/swistrack_opencv2 


cd swistrack_opencv2


cd SwisTrackEnvironment

Ubuntu 8.04Edit

On Ubuntu 8.04, it should be enough to install the packages

  • libwxgtk2.8-dev (wxWidgets)
  • libhighgui-dev (OpenCV)
  • libcvaux-dev (OpenCV)

Use Synaptic Packet Manager or type

sudo apt-get install libwxgtk2.8-dev
sudo apt-get install libhighgui-dev libcvaux-dev

on the terminal to install these packages.

Other distributionsEdit

If your distribution does not provide a package, you can compile and install these libraries manually.

Manually Installing OpenCVEdit

Download the OpenCV 1.0 sources [ http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/1.0/ ]and compile and install them:

tar xfz opencv-1.0.0.tar.gz
cd opencv-1.0.0
./configure --prefix=/usr
sudo make install

For detailed installation instructions, check out the INSTALL file.

Note that the current SwisTrack Makefile expects OpenCV to be installed with the prefix /usr. If you install it elsewhere, do not forget to modify the INCL_DIRS line in the Makefile appropriately.

When installing OpenCV 1.0 in newer Ubuntu distributions you may find the following issues:

1) Error message:

../../cxcore/include/cxmisc.h:133:6: error: #elif with no expression

To fix it, change line 133 in cxmisc.h from #elif to #else.

2) Error message:

../../../otherlibs/highgui/.libs/libhighgui.so: undefined reference to `cvCaptureFromCAM_V4L(int)'

To fix it, add #define HAVE_CAMV4L after line 24 in cvconfig.h

3) Error message:

cvcap_v4l.cpp:208:28: fatal error: linux/videodev.h: No such file or directory 

To fix it, install libv4l-dev and link to it with the following commands:

sudo apt-get install libv4l-dev
sudo ln -s /usr/include/libv4l1-videodev.h /usr/include/linux/videodev.h

Manually Installing wxWidgetsEdit

Download the wxWidgets 2.8.8 sources (either wxGTK or wxAll) [ http://sourceforge.net/projects/wxwindows/files/wxAll/2.8.8/ ] and compile and install them.

tar xfz wxWidgets-2.8.8.tar.gz
cd wxWidgets-2.8.8
sudo make install

You are free to change the prefix here, as SwisTrack uses 'wx-config' to locate wxWidgets.

Installing Optional LibrariesEdit

If you have a FireWire camera, install the 1394camera driver.

Checking out the latest SVN TreeEdit

Check out the latest SVN tree:

svn checkout https://svn.code.sf.net/p/swistrack/code

Compiling and LaunchingEdit

You can compile SwisTrack as follows:

cd code

This will compile libtsai (with a few warnings), camshift_wrapper, core and gui. The executable is stored as SwisTrackEnvironment/SwisTrack in the SVN tree. Lauch it as follows

cd SwisTrackEnvironment

Library PathsEdit

Depending on your system configuration, SwisTrack will complain about missing libraries. You may see error messages like this:

./SwisTrack: error while loading shared libraries: libwx_gtk2_aui-2.8.so.0: cannot open shared object file: No suchfile or directory

In this case, you need to set your LD_LIBRARY_PATH variable to point to the directory where these libraries are installed. If you are using a bash shell, this can be achieved as follows:

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

On Ubuntu 10.10 the following is required : export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH and create a dynamic link on the cvaux libs : sudo ln -s libcvaux.so.2.1 libcvaux.so in /usr/lib/
