Cross compiler opencv projet sur Ubuntu pour Raspberry Pi
Je suis aux prises avec ce pour 2 jours maintenant et de ne pas le faire fonctionner.
Ce que j'ai fait jusqu'à présent:
-
construit opencv 2.4.8 à partir de la source sur Ubuntu 12.04 LTS
--> OpenCV projets de compiler et d'exécuter sur ubuntu -
construit opencv 2.4.8 à partir de la source sur le Raspberry Pi Raspian
--> OpenCV projets de compiler et d'exécuter sur le Raspberry Pi -
construit un compilateur croisé pour le Raspberry Pi avec crosstools-ng (http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi/)
--> c++ programmes basés sur Ubuntu avec le crosscompiler exécuter sur le Raspberry Pi
Quels sont mes problèmes:
|2|fatal error: opencv2/highgui/highgui.hpp: No such file or directory|

SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
avec cette chaîne, j'ai essayé de cross compiler OpenCV avec cette commande:
cmake -DCMAKE_TOOLCHAIN_FILE=../Toolchain-RaspberryPi.cmake ../
Après la commande make il compile jusqu'à 27%. Là, il s'arrête avec cette erreur

Donc ma question est:
Comment puis-je obtenir un crosscompiler sur ubuntu pour travailler avec opencv? Je veux juste compiler sous ubuntu, copier le programme sur la Pi et de l'exécuter.
Merci beaucoup

Je réalise que c'est une vieille question, mais pour l'enregistrement, j'ai été capable de faire de la compilation croisée mon OpenCV projet de Ubuntu.
Dans mon cas j'ai utilisé le pré-construits raspberry pi de la chaîne sur github: https://github.com/raspberrypi/tools sur Ubuntu 12.0.4. J'ai pris l'approche de copier les librairies natives (avec OpenCV et PiCamera bibliothèques installées) à partir de la cible Raspberry Pi système d'Ubuntu en instance et à l'aide de la CMAKE_TOOLCHAIN_FILE soutien que vous mentionnez dans votre message.
Cependant, il y a certaines questions que j'ai dû surmonter, que je couvre dans ce post: https://solderspot.wordpress.com/2016/02/04/cross-compiling-for-raspberry-pi-part-ii
Les principaux points sont les suivants:
CMAKE_FIND_ROOT_PATH n'avait pas d'effet. J'ai eu à utiliser CMAKE_SYSROOT.
Dans mon CMakeLists.txt le fichier que j'avais encore explicitement ajouter les chemins d'accès par le chemin vers le dossier où j'avais copié sur le système de fichiers natif.
J'ai également nécessaire de spécifier explicitement la dynamique de la bibliothèque des chemins de liaison de l'intérieur CMAKE_TOOLCHAIN_FILE que la chaîne n'est pas correctement parser le fichier /usr/etc/ld..fichier conf.
Le seul problème je ne pouvais pas résoudre était encore à faire avec le Jessie version de Raspbian, comme OpenCV utilise un gcc/g++ 4.9 fonctionnalité qui n'est pas pris en charge par la gcc/g++ 4.8 version de la suite d'outils. Il ressemble à la chaîne de compilation sera augmentée à l'appui de 4,9 dans un avenir proche.
Mon dernier CMAKE_TOOLCHAIN_FILE était:
Où j'ai eu un pidev dossier dans mon répertoire home et en vertu de cette piroot avait une copie de /usr /opt /etc /lib de mon pi hôte, et pitools est un clone de la chaîne d'outils de GitHub j'référence ci-dessus.
Mon CMakeLists.txt fichier pour mon projet était:
Espère que cette aide.
sudo apt-get install libopencv-dev
sur mon pi et installé avec succès. Mais je ne trouve pas de libopencv*.donc, ni dans/usr/lib
,/lib
,/usr/local/lib
. Je ne trouve que les fichiers d'en-tête dans/usr/include/opencv
et/usr/include/opencv2
. Cependant, je suis sûr que je peux le compiler en local sur pi avec opencv, ne peut pas trouver l'emplacement de la libs.OriginalL'auteur solderspot
Vous pouvez cross compiler Qt (c++) avec OpenCV pour le raspberry pi en suivant ce lien:
http://aplacetogeek.wordpress.com/qt-opencv-v4l-cross-compiling-raspberry-pi-beagle-bone/
Ce lien devrait vous donner toutes les informations nécessaires sur la façon de rendre votre système qui permet de faire de la compilation croisée pour le raspberry pi. Lorsque vous avez tout mis en place la façon dont le lien dit, je pense que vous pouvez également utiliser la bibliothèque opencv pour traverser la compilation c++ sans Qt, si vous préférez.

J'ai suivi les étapes ci-dessus et j'en suis le foolowing erreur :
quelqu'un a réussi à faire de la compilation croisée d'un projet qui utilise opencv et la raspicam bibliothèques?
