Hi,
I am trying to build Qt4.8.0 on Redhat linux5.4.
I get following error, while building. It seems that it is related to webkit

Has anyone faced such a problem ? I had also tried building Qt4.6.4, which builds properly without any error.
Thank you for any help

Hello ludde and AcerExtensa,
Thanks a lot for responding.
@ ludde – I have already tried with -no-webkit option, while I was waiting for someone to reply here, and the builds were successful. I was just wondering If I am missing some prerequisites, because of which, I am getting build error in the standard Qt package.
@AcerExtensa -i will definitely give a try, to your suggestion
cc1plus: warnings being treated as errors
It’s definitely Werror flag somewhere. search for it:
You also can try to disable this warning:
warning: lowering visibility of
add -fpermessive to Project Makefile. or a better way, add
- QMAKE_CXXFLAGS = -fpermissive
to Qt project.pro… you also need to clean config and rerun configure.
Where is many way to diagnose and switch warnings in gcc. Read this [gcc.gnu.org]
Dear AcerExtensa,
I search for it using
grep -r “Werror” ./src/3rdparty/webkit
I just found QMAKE_CXXFLAGS += -Werror in Wenkit.pri .I remove it to configure and make. I got the errror as http://developer.qt.nokia.com/forums/viewthread/14542/
So, is there anything I miss?
Yes. I use cross-compiling Qt for arm device.
1. My Deshtop PC OS:Ubuntu 10.10
2. Toolchian: arm-2007q1-10-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar
3. I modify qt-everywhere-opensource-arc-4.8.0/mkspecs/qws/linux-arm-g++/qmake.conf as below:
============================================
#qmake configuration for building with arm-linux-g++ # #
include(../../common/linux.conf)
include(../../common/gcc-base-unix.conf)
include(../../common/g++-unix.conf)
include(../../common/qws.conf)
#modifications to g++.conf
QMAKE_CC = /usr/local/toolchain/arm-2007q1/bin/arm-none-linux-gnueabi-gcc
QMAKE_CXX = /usr/local/toolchain/arm-2007q1/bin/arm-none-linux-gnueabi-g++
QMAKE_LFLAGS = -Wl,-rpath=/home/tslib/lib
QMAKE_LINK = /usr/local/toolchain/arm-2007q1/bin/arm-none-linux-gnueabi-g++
QMAKE_LINK_SHLIB = /usr/local/toolchain/arm-2007q1/bin/arm-none-linux-guneabi-g++
#modifications to linux.conf
QMAKE_AR = /usr/local/toolchain/arm-2007q1/bin/arm-none-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = /usr/local/toolchain/arm-2007q1/bin/arm-none-linux-gnueabi-objcopy
QMAKE_STRIP = /usr/local/toolchain/arm-2007q1/bin/arm-none-linux-gnueabi-strip
QMAKE_INCDIR = /home/tslib/include QMAKE_LIBDIR = /home/tslib/lib
load(qt_config) ============================================
4. qt4.8.0 download from http://qt.nokia.com/downloads/embedded-linux-cpp5. My configure line: ./configure -prefix PATH -embedded arm -make tools -xplatform qws/linux-arm-g++ -v -qt-mouse-tslib -I’tslib PATH’/include -L’tslib PATH’/lib -qt-gfx-vnc
6. gcc -v shows gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5)
Thank you!
