Erreur lors de la compilation croisée Qt ​​pour un pi3 framboise

Question

Je veux croiser Qt pour développer un gui pour un pi de framboise. J'ai suivi ce tutoriel: https://wiki.qt.io/RaspberryPi2EGLFS

J'utilise cette commande configure:

./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option \ 
CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- \ 
-sysroot ~/raspi/sysroot -opensource -confirm-license \ 
-make libs -no-use-gold-linker -prefix /usr/local/qt5pi \ 
-extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v 

C'est l'erreur Je reviens:

Je ne sais pas où aller à partir d'ici, je ne sais pas assez pour démarrer le débogage ce problème. Existe-t-il d'autres chaînes d'outils disponibles? Ou est le problème avec le QMakeSpec? Toute suggestion sur les choses à essayer serait très utile.

Ce billet de blog semble plus spécifique à RPi3, et fait probablement aussi (dernier 12 janvier 2017):

Il y a une note sur le wiki que vous êtes à la recherche de certaines choses qu'ils ont faites pour l'obtenir pour travailler sur de nouvelles constructions. Voici l'histoire de cette page wiki:

https://wiki.qt.io/index.php?title=RaspberryPi2EGLFS&type=revision&diff=31538&oldid=30634

Et puis il y a la création de périphériques version sous licence de Qt vous pouvez ensuite utiliser ces instructions:

http://doc.qt.io/QtForDeviceCreation/qtee-preparing-hardware-rasberrypi.html

J'ai toujours appris beaucoup en creusant dans les articles sur Linux de Scratch. Dans ma récente construction de Qt avec rien, ils ont été super utiles.

http://www.linuxfromscratch.org/blfs/view/8.0/x/qt5.html

espère que ces liens aident.

Ceci est mon script bash pour la compilation croisée de Qt pour raspberry-pi. Vous pouvez ce script avec la commande <script name> <TcpIp of Raspberrry> $USER

Answer 3

I modifié périphérique mkspec fichier linux-rasp-pi3-g++/qmake.conf comme celui-ci

VC_LIBRARY_PATH   = $$[QT_SYSROOT]/opt/vc/lib 
VC_INCLUDE_PATH   = $$[QT_SYSROOT]/opt/vc/include 

QMAKE_LIBDIR_OPENGL_ES2 = $${VC_LIBRARY_PATH} 
QMAKE_LIBDIR_EGL  = $$QMAKE_LIBDIR_OPENGL_ES2 
QMAKE_LIBDIR_OPENVG  = $$QMAKE_LIBDIR_OPENGL_ES2 

QMAKE_INCDIR_EGL  = \ 
         $${VC_INCLUDE_PATH} \ 
         $${VC_INCLUDE_PATH}/interface/vcos/pthreads \ 
         $${VC_INCLUDE_PATH}/interface/vmcs_host/linux 
QMAKE_INCDIR_OPENGL_ES2 = $${QMAKE_INCDIR_EGL} 
QMAKE_INCDIR_OPENVG  = $${QMAKE_INCDIR_EGL} 

QMAKE_LIBS_OPENGL_ES2 = -lGLESv2 
QMAKE_LIBS_EGL   = -lEGL -lGLESv2 
QMAKE_LIBS_OPENVG  = -lEGL -lOpenVG -lGLESv2 

et utiliser gcc-linaro-4.9-2015.02-3-x86_64_arm-linux-gnueabihf toolchain.
