      Hi,
      I am using qt-everywhere-opensource-src-4.8.5 and cross compiled it for ARM(Cortex-a8) Ti-Am335x processor.
      I am able to run all qt example & demos . But when i am using qt-webkit browser(arora). It is getting crashed when opening any page by giving segmentation fault error.

      Thanks in advance.

        Hi and welcome to devnet,

        Did you run the application using a debugger ?

            Then I would recommend to first get one up and running

              Right now we cant afford a debugger. Any other alternative.

                  I have the same problem. Im runing windows 8 and the process crashes when I set any URL to the url parameter that by defualt has the value "about:blank".

                  I have debuged the application with IDa and there is an access violation in the ddl Qt5Core.dll:

                  538EC204: The instruction at 0x538EC204 referenced memory at 0xFEEEFEF2. The memory could not be read -> FEEEFEF2 (exc.code c0000005, tid 6960)

                  The process crashes and exits so this is a DoS bug that must be fixed.What is the process to do this fix?

                  Regards

                    Hi and welcome to devnet,

                    This is not the same problem, you are not using an ARM cross-compiled version of Qt running on linux and not using the same version of Qt

                      You are right. That means that this bug has been out there for a while...

                        Not necessarily no, however if you can come up with a minimal example that systematically crashes, then you may have found something.

                          SGaist,

                          I am running QtWebKit version 5.4.0 on TI am335x ARM processor and using TI SDK 5_01_01_01 for graphic drivers and library support., cross-compiled with arm-gnueabihf 4.7 (linaro).

                          I try to run 'browser' example listed as QtWebKitWidget example and I run into 'Segmentation Fault'

                          I am not asking you for a solution, because I know you will just point me use a bunch of other 3rd party tools to spit out a bunch of logs that take a pro know what it all means and then diagnose problem myself.

                          Being a Hall of Fame Certified Qt Specialist, I was wondering if you could point me to a Qt forum thread where someone has actually got QtWebKit's working for ARM. Any ARM. Any Qt version greater than or equal to 5. I can find no forums, no examples, no steps how to get QtWebKit examples going. No help from Qt or other sources.

                          Thanks.

                                      Hey vattipalli, I'd be happy to share with you some of my build time materials for QtWebKit.

                                      1. It is important to note that my build environment is for OpenEmbedded based on the Yocto project, so I used the meta-qt5 bitbake recipes. The patches used for Qt5.4.0 are listed here:
                                        https://github.com/meta-qt5/meta-qt5/tree/master/recipes-qt/qt5/qtbase
                                        https://github.com/meta-qt5/meta-qt5/tree/master/recipes-qt/qt5/qtwebkit

                                      2. My qmake.conf is listed in qtbase-opensource-src-5.4.0/mkspecs/linux-oe-g++ . You can find the qtbase-opensource-src tarball here: http://download.qt.io/official_releases/qt/5.4/5.4.0/submodules/

                                      This is what my qmake.conf looks like:
                                      @MAKEFILE_GENERATOR = UNIX
                                      CONFIG += incremental
                                      QMAKE_INCREMENTAL_STYLE = sublib

                                      include(../common/linux.conf)

                                      QMAKE_<TOOL> (moc, uic, rcc) are gone, overwrite only ar and strip

                                      QMAKE_AR = $(OE_QMAKE_AR) cqs
                                      QMAKE_STRIP = $(OE_QMAKE_STRIP)
                                      QMAKE_WAYLAND_SCANNER = $(OE_QMAKE_WAYLAND_SCANNER)

                                      include(../common/gcc-base-unix.conf)

                                      *FLAGS from gcc-base.conf

                                      QMAKE_CFLAGS += $(OE_QMAKE_CFLAGS)
                                      QMAKE_CXXFLAGS += $(OE_QMAKE_CXXFLAGS)
                                      QMAKE_LFLAGS += $(OE_QMAKE_LDFLAGS)

                                      include(../common/g++-unix.conf)

                                      tc settings from g++-base.conf

                                      QMAKE_COMPILER = $(OE_QMAKE_COMPILER)
                                      QMAKE_CC = $(OE_QMAKE_CC)
                                      QMAKE_CXX = $(OE_QMAKE_CXX)

                                      QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += $(OE_QMAKE_CFLAGS)

                                      QMAKE_LINK = $(OE_QMAKE_LINK)
                                      QMAKE_LINK_SHLIB = $(OE_QMAKE_LINK)
                                      QMAKE_LINK_C = $(OE_QMAKE_LINK)
                                      QMAKE_LINK_C_SHLIB = $(OE_QMAKE_LINK)

                                      for the SDK

                                      isEmpty(QMAKE_QT_CONFIG):QMAKE_QT_CONFIG = $(OE_QMAKE_QT_CONFIG)

                                      load(qt_config)@

                                      1. Another point that is important to get QtWebKits compiled & installed is to make sure your configuration options are enabled/disabled correctly. For example, the ICU (international components for unicode) needs to be enabled when configuring Qt base, which passes on these configuration options to QtWebKits.
                                        Listed below are my configuration options that I set:
                                        @ ${S}/configure -v
                                        -opensource -confirm-license
                                        -sysroot ${STAGING_DIR_TARGET}

                                        Hey vattipalli, I'd be happy to share with you some of my build time materials for QtWebKit.

                                        1. It is important to note that my build environment is for OpenEmbedded based on the Yocto project, so I used the meta-qt5 bitbake recipes. The patches used for Qt5.4.0 are listed here:
                                          https://github.com/meta-qt5/meta-qt5/tree/master/recipes-qt/qt5/qtbase
                                          https://github.com/meta-qt5/meta-qt5/tree/master/recipes-qt/qt5/qtwebkit

                                        2. My qmake.conf is listed in qtbase-opensource-src-5.4.0/mkspecs/linux-oe-g++ . You can find the qtbase-opensource-src tarball here: http://download.qt.io/official_releases/qt/5.4/5.4.0/submodules/

                                        This is what my qmake.conf looks like:
                                        @MAKEFILE_GENERATOR = UNIX
                                        CONFIG += incremental
                                        QMAKE_INCREMENTAL_STYLE = sublib

                                        include(../common/linux.conf)

                                        QMAKE_<TOOL> (moc, uic, rcc) are gone, overwrite only ar and strip

                                        QMAKE_AR = $(OE_QMAKE_AR) cqs
                                        QMAKE_STRIP = $(OE_QMAKE_STRIP)
                                        QMAKE_WAYLAND_SCANNER = $(OE_QMAKE_WAYLAND_SCANNER)

                                        include(../common/gcc-base-unix.conf)

                                        *FLAGS from gcc-base.conf

                                        QMAKE_CFLAGS += $(OE_QMAKE_CFLAGS)
                                        QMAKE_CXXFLAGS += $(OE_QMAKE_CXXFLAGS)
                                        QMAKE_LFLAGS += $(OE_QMAKE_LDFLAGS)

                                        include(../common/g++-unix.conf)

                                        tc settings from g++-base.conf

                                        QMAKE_COMPILER = $(OE_QMAKE_COMPILER)
                                        QMAKE_CC = $(OE_QMAKE_CC)
                                        QMAKE_CXX = $(OE_QMAKE_CXX)

                                        QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += $(OE_QMAKE_CFLAGS)

                                        QMAKE_LINK = $(OE_QMAKE_LINK)
                                        QMAKE_LINK_SHLIB = $(OE_QMAKE_LINK)
                                        QMAKE_LINK_C = $(OE_QMAKE_LINK)
                                        QMAKE_LINK_C_SHLIB = $(OE_QMAKE_LINK)

                                        for the SDK

                                        isEmpty(QMAKE_QT_CONFIG):QMAKE_QT_CONFIG = $(OE_QMAKE_QT_CONFIG)

                                        load(qt_config)@

                                        1. Another point that is important to get QtWebKits compiled & installed is to make sure your configuration options are enabled/disabled correctly. For example, the ICU (international components for unicode) needs to be enabled when configuring Qt base, which passes on these configuration options to QtWebKits.
                                          Listed below are my configuration options that I set:
                                          @ ${S}/configure -v
                                          -opensource -confirm-license
                                          -sysroot ${STAGING_DIR_TARGET}
