I started a bisect qtwebkit and when I try to compile it in the first stage it gave me the following exception. I tried using a older qmake but still it gives the same exception. What does this really mean and how can I fix it.

IMHO ll. 2,3 is important:
error "This file was generated using the moc from 4.8.0. It"
error "cannot be used with the include files from this version of Qt."
Your reach a version less than qt 4.8 and all your moc-files were generated in a previous build by moc v4.8. You have to clean your build directory and restart your build command (ensure you use a proper version of qmake, moc etc.).

I am using QT Binding/Wrapper for Go in my project. Project is compiling fine for amd64 but when I try to compile project for arm devices, it gives me below error

I am trying compile a pexe file using the portable native client. I am following the instructions at this page:
https://developer.chrome.com/native-client/devguide/devcycle/building
I am trying to build a pexe and link it with a static lib as shown on the page. My command line is as follows.
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/bin/pnacl-clang++ -o pim-pnacl.pexe pim-pnacl.o -L/home/adev/opt/nacl_sdk/pepper_37/lib/pnacl/Release -lppapi_cpp -lppapi -L../libpidec -lpidec
and I get the following errors.
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/sdk/lib/libppapi_stub.a: error: undefined reference to 'PPP_GetInterface'
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/sdk/lib/libppapi_stub.a: error: undefined reference to 'PPP_ShutdownModule'
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/sdk/lib/libppapi_stub.a: error: undefined reference to 'PPP_InitializeModule'
For the record, the problem was in the pim-pnacl.o it needed to be compiled with the -c flag. This is the correct way to compile a single .o file:
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/bin/pnacl-clang++ -o pim-pnacl.o pim-pnacl.cc -O2 -I/home/adev/opt/nacl_sdk/pepper_37/include -c
I had omitted the -c and this caused linker problems.
I am trying to compile Qt embedded for ARM. I have followed the instructions both here and here. I am using latest Angstrom toolchain and qt-embedded-linux-opensource-src-4.5.3 and I am using Ubuntu 10.10 x86.
Here steps I past:
Configured qws/linux-arm-g++/qmake.conf file for my toolchain. Here it's content:
#
# qmake configuration for building with arm-linux-g++
#
include(../../common/g++.conf)
include(../../common/linux.conf)
include(../../common/qws.conf)
# modifications to g++.conf
QMAKE_CC = arm-angstrom-linux-gnueabi-gcc
QMAKE_CXX = arm-angstrom-linux-gnueabi-g++
QMAKE_LINK = arm-angstrom-linux-gnueabi-g++
QMAKE_LINK_SHLIB = arm-angstrom-linux-gnueabi-g++
# modifications to linux.conf
QMAKE_AR = arm-angstrom-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = arm-angstrom-linux-gnueabi-objcopy
QMAKE_STRIP = arm-angstrom-linux-gnueabi-strip
load(qt_config)
Set my toolchain path:
export PATH=/home/olcay/angstrom/arm/bin:$PATH
Configured qt with:
./configure -arch arm -little-endian -xplatform qws/linux-arm-g++
Run make.
While running make I am getting this error:
make[1]: Entering directory `/home/olcay/qt-embedded/src/corelib'

make[1]: Leaving directory `/home/olcay/qt-embedded/src/corelib'
make: *** [sub-corelib-make_default-ordered] Error 2
I have also noticed that while config there is a warning and same error line in make:
The system floating point format could not be detected.
This may cause data to be generated in a wrong format
Turn on verbose messaging (-v) to see the final report.
/home/olcay/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++: 1: ELF: not found
/home/olcay/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++: 2: Syntax error: word unexpected (expecting ")")
And changing configure line as #Luca Carlon described does not solve the problem.
Please help me!
Thanks in advance.
I have noticed that I have downloaded my Angstrom tool-chain for 64 bit host platform but I am using 32 bit host. After downloading correct tool-chain I have managed to compile Qt. And I found that an "ELF not found" error occurs when you try to run an application which is not build for your architecture.
Replace -arch arm with -embedded arm and try again if you want to build Qt Embedded.
I'm trying to use a QGLWidget in a QT application, and I've added the "QT += opengl" line into the .pro file but I am now getting :: error: collect2: ld returned 1 exit status when I attempt to compile my program

Error while building project MapEditor (target: Desktop)
When executing build step 'Make'
and my .pro file contains the following,
TARGET = MapEditor
TEMPLATE =app
QT += opengl
SOURCES += \
Main.cpp \
window.cpp \
glwidget.cpp
HEADERS += \
window.h \
glwidget.h
Check you .pro file (i.e. project file) that u have added all the class files and header files in SOURCES and HEADERS tags.[For this purpose run qmake command from build menubar options]
Also check that u have declared the Q_OBJECT macro in the starting of your glwidget class.
It looks like some file is missing. Did you add this to your header?

I'm trying to use QtService from QtSolution in a Qt project.
I've unzipped it and run:
configure.bat -library
qmake
mingw32-make
the debug and release dll were placed inside C:\Qt\2010.03\qt\bin\
Examples were correctly built .
I added this line at the bottom of my .pro file:
include(../QtSolutions/qtservice/src/qtservice.pri)
and I was able to browse the qtservice's sources from the project source tree.
When I try to build my project I get:

Thank you for your time.
Just a guess: I don't see a include -IC:\Qt\2010.03\qt\include in your call of g++. So the compiler can't find the Qt Headers. I tink there is something wrong in your EMCSolutionCrawler.pro.
