    Adds "armvX-none-rvct" targets · 11a222f5
    Tero Rintaluoma authored 
    Adds following targets to configure script to support RVCT compilation
without operating system support (for Profiler or bare metal images).
 - armv5te-none-rvct
 - armv6-none-rvct
 - armv7-none-rvct

To strip OS specific parts from the code "os_support"-config was added
to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS
specific parts such as OS specific includes and function calls for
timers and threads etc. This was done to enable RVCT compilation for
profiling purposes or running the image on bare metal target with
Lauterbach.

Removed separate AREA directives for READONLY data in armv6 and neon
assembly files to fix the RVCT compilation. Otherwise
"ldr <reg>, =label" syntax would have been needed to prevent linker
errors. This syntax is not supported by older gnu assemblers.

\title Porting QML Applications to Qt 5 Example
30 
\brief Provides step-by-step instructions to port a QML application to Qt 5.
31
32 
The new version of Qt Quick in Qt 5 brings in some changes to the way QML
33 
applications are developed. For the complete list of changes that affect
34 
existing QML applications, refer to \l{Porting QML Applications to Qt 5}.
35
36 
This topic will walk through the porting process to make the \c{flickr} Qt 4
37 
QML demo work on Qt 5. If you have the SDK based on Qt 4.8 installed, you can
38 
find this demo application under
39 
\c{<install_dir_root>/Examples/4.x/declarative/demos/}.
40
41 
The \c{flickr} application is a complete application that comes with a launcher.
42
43 
Follow these step-by-step instructions to make the \e{flickr} Qt 4 QML
44 
application work on Qt 5:
45 
\list 1
46 
 \li Edit all the \c{.qml} files and replace \c{import QtQuick 1.0} statements
47 
     with \c{import QtQuick 2.0}.
48 
 \li Add the additional \c{import QtQuick.XmlListModel 2.0} statement to
49 
     \c{qml/common/RssModel.qml}.
50 
     \note XmlListModel is part of a submodule under QtQuick and it must be
51 
           imported explicitly to use it.
52 
 \li Make the following changes to
53 
     \c{qmlapplicationviewer/qmlapplicationviewer.h}:
54 
  \list
55 
   \li Replace the \c{#include <QtDeclarative/QDeclarativeView>} with
56 
       \c{#include <QQuickView>}.
57 
   \li Replace \c{QDeclarativeView} with \c{QQuickView} in the class
58 
       declaration for \c{QmlApplicationViewer}.
59 
   \li Replace the parameter for \c{QmlApplicationViewer} constructor from
60 
       \c{QWidget} to \c{QWindow}.
61 
  \endlist
62 
 \li Make the following changes to
63 
     \c{qmlapplicationviewer/qmlapplicationviewer.cpp}:
64 
  \list
65 
   \li Replace all the \c{QtCore} and \c{QtDeclarative} include statements with
66 
       these:
67 
    \code
68 
      #include <QCoreApplication>
69 
      #include <QDir>
70 
      #include <QFileInfo>
71727374757677787980818283848586878889909192939495
#include <QQmlComponent> #include <QQmlEngine> #include <QQmlContext> #include <QDebug> \endcode \li Replace all instances of \c{QWidget} with \c{QWindow}, and \c{QDeclarativeView} with \c{QQuickView}. \li Remove the code between \c{#if defined(Q_OS_SYMBIAN)} and \c{#endif} macros as Symbian platform is not supported in Qt 5. \li Remove the code between \c{#if QT_VERSION < 0x040702} and \c{#else}, and \c{#endif // QT_VERSION < 0x040702} macros towards the end. \endlist \li Run the \c{qmake} and \c{make} utilities to build the application. \note Ensure that the \c{PATH} environment variable is pointing to the Qt 5 binaries and libraries directories, before running \c{qmake}. \endlist Run the \c{flickr} application to see whether it behaves as expected. Here is a snapshot of the application running on Ubuntu v12.04: \image flickr_application.png \section1 Related Topics \l{Porting QML Applications to Qt 5} */
