Unable to Build Qt Code on Raspberry Pi

[Abin]

Hi,

Past few weeks I have been trying to setup Qt native build environment in Raspberry Pi board.

I followed steps mentioned in Native Build of Qt 5.4.1

Since I do not use USD Hard Disk, I omitted few steps
-Unpacking source to an external USB HDD
-Increasing available RAM for concurrent compilation

Instead I extracted to moved to path : cd ~/opt/qt-everywhere-opensource-src-5.4.1

and for compilation I run : make 2>&1 | tee make.out

I tried Qt 5.4.1 version to build on Jessie version of raspbian OS, but it failed. I found similar error someone posted and tried to reply but no response at the end. link text

And now I tried Qt 5.4.1 on Wheezy version, and I get different error.

/home/pi/opt/qt-everywhere-opensource-src-5.4.1/qtwebkit/Source/JavaScriptCore//libJavaScriptCore.a: member /home/pi/opt/qt-everywhere-opensource-src-5.4.1/qtwebkit/Source/JavaScriptCore//.obj/dfg/DFGThunks.o in archive is not an object

Can someone tell me why this occurs? Is this Qt code issue? Is there a way to resolve this?

Provide a qmake.conf file

[Abin]

@Zola I have seen many qmake.conf file in the Qt source code. I am confused which to take.

I took the file ./opt/qt-everywhere-opensource-src-5.4.1/qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

#
# 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)

# 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)

@Abin
Make your qmake.conf file to look like this:

modifications to g++.conf

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

modifications to linux.conf

QMAKE_AR = arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabihf-objcopy
QMAKE_NM = arm-linux-gnueabihf-nm -P
QMAKE_STRIP = arm-linux-gnueabihf-strip
load(qt_config)

Try to goes through these steps for your RPi
