Install opencv2.0 on Ubuntu8.10 missing libunicap, libucil and libv4l1

installation

Basically, I am trying to build opencv 2.0 via CMake on Ubuntu 8.10. It keeps saying libunicap, libucil and libv4l1 are missing on my system. I searched for the packages for these libraries on places like Synaptic Package Manager but found none except that on http://packages.ubuntu.com there are some similar ones like libunicap2 libucil2 , which cannot be installed on my Ubuntu due to "installation error: Dependency is not satisfiable".

Here is the missing library info reported by CMake:

I also tried to install the pre-required libraries specified for earlier version of OpenCV, which I found online, but found they are already installed:

$ sudo apt-get install libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg62-dev libtiff4-dev     
Reading package lists... Done     
Building dependency tree            
Reading state information... Done     
libgtk2.0-dev is already the newest version.     
libavcodec-dev is already the newest version.     
libavformat-dev is already the newest version.     
libjpeg62-dev is already the newest version.     
libtiff4-dev is already the newest version.     
The following packages were automatically installed and are no longer required:     
  dnsmasq-base ttf-liberation     
Use 'apt-get autoremove' to remove them.     
0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.

So I am puzzled. Anyone can give some advice please?

Thanks and regards!

unfortunately there are no unicap and ucil packages for ubuntu hardy. This does not mean that you can not compile and use openCV-2.0 in your applications but only that you will miss the functionalities offered by these specific libraries.

After running cmake you just have to compile and install OpenCV using:

$ make
$ sudo make install

from the same directory where you executed cmake.

Then you can compile and link your applications with OpenCV following the infos in the last section of the INSTALL file.
