Estou tendo problemas ao tentar instalar o OpenCV 2.0 no Ubuntu 14.04. Quando eu quero instalar as dependências eu tenho o seguinte problema:
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:

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.
Eu quero instalar o OpenCV 2.0 porque existe um projeto antigo que usa essa versão do OpenCV.

1: Eu instalei o libtiff5-dev, mas ele gerou outro erro:
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.
Então eu removi o libjpeg-turbo8-dev mas ele desinstalou o libtiff5-dev. Alguém postou sobre o problema há 4 anos sem uma solução:

Eu usei o aptitude em vez do apt-get para instalar as dependências. Tudo correu bem, mas eu verifiquei que eu tenho ffmpeg e v4l como não. Eu não me importei e tentei compilar a biblioteca. Eu tenho os seguintes erros de compilação:
