Risposte:
Ieri sera ho appena creato la versione 3.0.0-beta sulla versione B. Dovrebbe essere lo stesso in un B +.
Di seguito sono riportati i passaggi che ho fatto per costruirlo dal sorgente (adattato da: http://robertcastle.com/2014/02/installing-opencv-on-a-raspberry-pi/ ). Spero che sia d'aiuto.
Assicurati che il tuo sistema sia aggiornato. Correre:
sudo apt-get update sudo apt-get upgrade sudo rpi-update
Dipendenze necessarie per l'installazione successiva:
sudo apt-get install build-essential cmake cmake-curses-gui \
pkg-config libpng12-0 libpng12-dev libpng ++ - dev \
libpng3 libpnglite-dev zlib1g-dbg zlib1g zlib1g-dev \
pngtools libtiff4-dev libtiff4 libtiffxx0c2 libtiff-tools libeigen3-dev
sudo apt-get install libjpeg8 libjpeg8-dev libjpeg8-dbg libjpeg-progs \
ffmpeg libavcodec-dev libavcodec53 libavformat53 \
libavformat-dev libxine1-ffmpeg libxine-dev libxine1-bin \
libunicap2 libunicap2-dev swig libv4l-0 libv4l-dev \
python-numpy libpython2.6 python-dev python2.6-dev libgtk2.0-dev
Ora la parte interessante, passa a una directory per mettere i sorgenti e compilare OpenCV.
cd / home / pi / builds / git clone https://github.com/Itseez/opencv.git cd opencv / tag di checkout git / 3.0.0-beta rilascio di mkdir versione cd / ccmake ../
Premere c per avviare il processo di configurazione. Se lo desideri, puoi attivare alcune opzioni, le mie opzioni finali sono di seguito. Se si modifica un'opzione, premere di nuovo c per configurare. Ora premi g per generare il Makefile. Ora continua il processo di generazione, nota che il comando make richiederà diverse ore (ci sono volute 7 ore sul mio modello raspberry pi B).
rendere sudo make install sudo ldconfig
Ecco le impostazioni delle opzioni utilizzate nel passaggio di configurazione:

Quando si compila secondo la risposta di Miguel, farlo con a
>> make -j4Sul modello raspberry pi 2-B / B-2 questo può accelerare significativamente la compilazione man mano che viene fatto l'uso di tutti i core.
NOTA: se viene visualizzato un errore durante la compilazione con questa opzione, basta usare
makeper risolverlo.
