I'm having problems trying to install OpenCV 2.0 on Ubuntu 14.04. When I want to install the dependencies I got the following problem:
andres@andres-VirtualBox:~$ sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg62-dev libtiff4-dev cmake libswscale-dev libjasper-dev
[sudo] password for andres:

Done Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created or been
moved out of Incoming. The following information may help to resolve the
situation:
The following packages have unmet dependencies:
libtiff4-dev : Depends: libtiff5-dev (> 4.0.3-6~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I want to install OpenCV 2.0 because there is an old project that uses that version of OpenCV.
Update 1
1: I installed libtiff5-dev but then it threw another error:
The following packages have unmet dependencies:
libjpeg-turbo8-dev : Conflicts: libjpeg62-dev but 6b1-4ubuntu1 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
Then I removed libjpeg-turbo8-dev but it uninstalled libtiff5-dev. Someone posted about the problem like 4 years ago without a solution:

Update 2
I used aptitude instead of apt-get to install the dependencies. Everything went ok but I checked that I have ffmpeg and v4l as no. I didn't care and I tried to compile the library. I got the following compilation errors:

: I suggest you try removing that package from the prerequisite list and seeing if you can configure the build anyhow#include <cstddef>
to its list of standard headers: see here code.opencv.org/issues/1028
