Installer des en-têtes Python2.7 et 3 bras dans une machine à architecture AMD64
Je me bats parce que je veux compiler de manière croisée une application qui nécessite le Python à compiler. Juste au cas où vous seriez curieux de savoir que si le fichier pyconfig.h est utilisé, il essaie d’inclure le fichier suivant:
arm-linux-gnueabihf/python2.7/pyconfig.h
Ce qui malheureusement n'existe pas. Ensuite, j'aimerais installer les en-têtes python. J'ai donc procédé comme suit:
Sudo dpkg --add-architecture armhf
Sudo apt-get update
Et je reçois la sortie suivante,

J'ai cherché sur Internet et beaucoup de gens ont dit que la solution consistait à différencier dans le fichier /etc/apt/sources.list les référentiels des architectures Armhf et ceux correspondant à AMD64, i386. Cela ne marche pas du tout (et je ne sais pas si je l'ai bien fait, je ne sais pas grand chose à propos de sources.list), quand j'exécute cette commande:
Sudo apt-get install libpython2.7-dev:armhf
Je reçois:
The following packages have unmet dependencies:
libpython2.7-dev:armhf : Depends: libpython2.7-stdlib:armhf (= 2.7.12-1ubuntu0~16.04.2) but it is not going to be installed
Depends: libpython2.7:armhf (= 2.7.12-1ubuntu0~16.04.2) but it is not going to be installed
Depends: libexpat1-dev:armhf but it is not going to be installed
Recommends: libc6-dev:armhf but it is not going to be installed or
libc-dev:armhf
E: Unable to correct problems, you have held broken packages
Savez-vous à quelle étape je me suis planté? Je ne suis pas sûr, j'apprécierai votre aide, merci.
Je ne pouvais pas résoudre ce problème mais j'ai réussi à compiler, le pyconf.h nécessitant le arm-linux-gnueabihf-hf pyconf.h, j'ai donc installé dans mon périphérique ARM les python2.7 et python3.5 paquets de développement (python-dev et python3-dev) et copiés sur mon PC à l’emplacement où ils recherchaient ces fichiers pyconf.h. N'est-ce pas élégant, je ne l'aime pas, mais ça marche.
