QT cross compile issue on ubuntu 14.04

pramod jadhav

Hi,
I am trying to cross compile QT5.6 on Ubuntu14.04(for cubieboard4).I have copied related files & library from cubieboard 4 to my usr directory & tried to compile the QT using below command,

./configure -xplatform linux-arm-gnueabi-g++ -opengl -verbose

But it gives me error,

OpenGL ES 2.0 disabled.
All the OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL in
/home/pramodj/QT-Opensource/qt-everywhere-opensource-src-5.6.0-rc/qtbase/mkspecs/linux-arm-gnueabi-g++.

I have also changed the path in qmake.conf file.Below is the content of qmake.conf file

qmake configuration for building with arm-linux-gnueabi-g++

MAKEFILE_GENERATOR = UNIX
CONFIG += incremental
QMAKE_INCREMENTAL_STYLE = sublib

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

#include openGL libraries

QMAKE_INCDIR_OPENGL = /usr/arm-linux-gnueabihf/include/GL
QMAKE_LIBDIR_OPENGL = /usr/arm-linux-gnueabihf/
QMAKE_LIBS_OPENGL = -lglut -lGLU -lGL
QMAKE_LIBDIR_X11 = /usr/arm-linux-gnueabihf/

modifications to g++.conf

QMAKE_CC = arm-linux-gnueabi-gcc
QMAKE_CXX = arm-linux-gnueabi-g++
QMAKE_LINK = arm-linux-gnueabi-g++
QMAKE_LINK_SHLIB = arm-linux-gnueabi-g++

modifications to linux.conf

QMAKE_AR = arm-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabi-objcopy
QMAKE_NM = arm-linux-gnueabi-nm -P
QMAKE_STRIP = arm-linux-gnueabi-strip

load(qt_config)

I am new to QT. Any help will be appreciated

Hi,

Where did you put the files you copied from the CubieBoard root filesystem ? Why not use the rootfs option of configure ?

pramod jadhav

Thanks for your reply. I have put the files in usr directory. My path is /usr/arm-linux-gnueabihf .

You copied all the sysroot in /usr/arm-linux-gnueabihf

Please provide a link or document to cross compile QT.I have tried to copy sysroot in /usr/arm-linux-gnueabihf but no effect.

A quick search with cubieboard and Qt 5 turns this

Note that you should also contact the cubieboard community.
