\title Installing Qt on X11 Platforms
\ingroup installation
\brief How to install Qt on platforms with X11.
\previouspage Installation

\note Qt for X11 has some requirements that are given in more detail
in the \l{Qt for X11 Requirements} document.

\list 1
\o  If you have the commercial edition of Qt, install your license
    file as \c{$HOME/.qt-license}.

    For the open source version you do not need a license file.

\o  Unpack the archive if you have not done so already. For example,
    if you have the \c{qt-everywhere-opensource-src-4.6.1.tar.gz}
    package, type the following commands at a command line prompt:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 0

    This creates the directory \c{/tmp/qt-everywhere-opensource-src-4.6.1}
    containing the files from the archive. We only support the GNU version of
    the tar archiving utility. Note that on some systems it is called gtar.

\o  Building

    To configure the Qt library for your machine type, run the
    \c{./configure} script in the package directory.

    By default, Qt is configured for installation in the
    \c{/usr/local/Trolltech/Qt-4.6.1} directory, but this can be
    changed by using the \c{-prefix} option.

\snippet doc/src/snippets/code/doc_src_installation.qdoc 1

    Type \c{./configure -help} to get a list of all available options.

    To create the library and compile all the demos, examples, tools,
    and tutorials, type:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 2

    If \c{-prefix} is outside the build directory, you need to install
    the library, demos, examples, tools, and tutorials in the appropriate
    place. To do this, type:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 3

    , as root if necessary.

    Note that on some systems the make utility is named differently,
    e.g. gmake. The configure script tells you which make utility to
    use.

    \bold{Note:} If you later need to reconfigure and rebuild Qt from the
    same location, ensure that all traces of the previous configuration are
    removed by entering the build directory and typing \c{make confclean}
    before running \c configure again.

\o  Environment variables

    In order to use Qt, some environment variables needs to be
    extended.

\snippet doc/src/snippets/code/doc_src_installation.qdoc 4

    This is done like this:

    In \c{.profile} (if your shell is bash, ksh, zsh or sh), add the
    following lines:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 5

    In \c{.login} (in case your shell is csh or tcsh), add the following line:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 6

    If you use a different shell, please modify your environment
    variables accordingly.

    For compilers that do not support rpath you must also extended the
    \c LD_LIBRARY_PATH environment variable to include
    \c{/usr/local/Trolltech/Qt-4.6.1/lib}. On Linux with GCC this step
    is not needed.

\o  That's all. Qt is now installed.

    If you are new to Qt, we suggest that you take a look at the demos
    and examples to see Qt in action. Run the Qt Examples and Demos
    either by typing \c qtdemo on the command line or through the
    desktop's Main menu.

    You might also want to try the following links:

    \endlist
\endlist

    We hope you will enjoy using Qt. Good luck!

\title Installing Qt on Windows
\ingroup installation
\brief How to install Qt on Windows.
\previouspage Installation

\note Qt for Windows has some requirements that are given in more detail
in the \l{Qt for Windows Requirements} document.

\table
\row \o \bold{Notes:}
\list
\o If you have obtained a binary package for this platform,
consult the installation instructions provided instead of the ones in
this document.
\o \l{Open Source Versions of Qt} is not officially supported for use with
any version of Visual Studio. Integration with Visual Studio is available
as part of the \l{Qt Commercial Editions}.

\endlist
\endtable

\list 1
\o  If you have the commercial edition of Qt, copy the license file
    from your account on dist.trolltech.com into your home directory
    (this may be known as the \c userprofile environment variable) and
    rename it to \c{.qt-license}. This renaming process must be done
    using a \e{command prompt} on Windows, \bold{not} with Windows Explorer.
    For example on Windows 2000, \c{%USERPROFILE%} should be something
    like \c{C:\Documents and Settings\username}

    For the open source version you do not need a license file.

\o  Uncompress the files into the directory you want Qt installed;
    e.g. \c{C:\Qt\4.6.1}.

    \note The install path must not contain any spaces or Windows specific
    file system characters.

\o Environment variables

    In order to build and use Qt, the \c PATH environment variable needs to be
    extended:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 7

    This is done by adding \c{c:\Qt\4.6.1\bin} to the \c PATH variable.

    For newer versions of Windows, \c PATH can be extended through
    the \menu{Control Panel|System|Advanced|Environment variables} menu.

    You may also need to ensure that the locations of your compiler and
    other build tools are listed in the \c PATH variable. This will depend
    on your choice of software development environment.

    \bold{Note}: If you don't use the configured shells, which is
    available in the application menu, in the \l{Open Source Versions of Qt},
    \c configure requires that \c sh.exe is not in the path
    or that it is run from \c msys. This also goes for mingw32-make.

\o Building

    To configure the Qt library for your machine, type the following command
    in a \bold{Visual Studio} command prompt:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 8

    Type \c{configure -help} to get a list of all available options.

    If you have multiple compilers installed, and want to build the Qt library
    using a specific compiler, you must specify a \c qmake specification.
    This is done by pasing \c{-platform <spec>} to configure; for example:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 9

    In some cases you need to set up the compilation environment before running
    configure in order to use the right compiler. For instance, you need to do this
    if you have Visual Studio 2005 installed and want to compile Qt using the x64
    compiler because the 32-bit and 64-bit compiler both use the same
    \c qmake specification file.
    This is usually done by selecting
    \menu{Microsoft Visual Studio 2005|Visual Studio Tools|<Command Prompt>}
    from the \gui Start menu.

    The actual commands needed to build Qt depends on your development
    system. For Microsoft Visual Studio to create the library and
    compile all the demos, examples, tools and tutorials type:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 10

    \note If you later need to reconfigure and rebuild Qt from the
    same location, ensure that all traces of the previous configuration are
    removed by entering the build directory and typing \c{nmake distclean}
    before running \c configure again.

\o  That's all. Qt is now installed.

    If you are new to Qt, we suggest that you take a look at the demos
    and examples to see Qt in action. Run the Qt Examples and Demos
    either by typing \c qtdemo on the command line or through the
    desktop's Start menu.

/*! \page install-mac.html
\title Installing Qt on Mac OS X
\ingroup installation
\brief How to install Qt on Mac OS X.
\previouspage Installation

\note Qt for Mac OS X has some requirements that are given in more detail
in the \l{Qt for Mac OS X Requirements} document.

\bold{Note for the binary package}: If you have the binary package, simply double-click on the Qt.mpkg
and follow the instructions to install Qt. You can later run the \c{uninstall-qt.py}
script to uninstall the binary package. The script is located in /Developer/Tools and
must be run as root.

The following instructions describe how to install Qt from the source package.

\list 1
\o  If you have the commercial edition of Qt, install your license
    file as \c{$HOME/.qt-license}.

    For the open source version you do not need a license file.

\o  Unpack the archive if you have not done so already. For example,
    if you have the \c{qt-everywhere-opensource-src-4.6.1.tar.gz}
    package, type the following commands at a command line prompt:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 11

    This creates the directory \c{/tmp/qt-everywhere-opensource-src-4.6.1}
    containing the files from the archive.

\o  Building

    To configure the Qt library for your machine type, run the
    \c{./configure} script in the package directory.

    By default, Qt is configured for installation in the
    \c{/usr/local/Trolltech/Qt-4.6.1} directory, but this can be
    changed by using the \c{-prefix} option.

\snippet doc/src/snippets/code/doc_src_installation.qdoc 12

    Type \c{./configure -help} to get a list of all available options.

    Note that you will need to specify \c{-universal} if you want to
    build universal binaries, and also supply a path to the \c{-sdk}
    option if your development machine has a PowerPC CPU. By default,
    Qt is built as a framework, but you can built it as a set of
    dynamic libraries (dylibs) by specifying the \c{-no-framework}
    option.

    Qt can also be configured to be built with debugging symbols. This
    process is described in detail in the \l{Debugging Techniques}
    document.

    To create the library and compile all the demos, examples, tools,
    and tutorials, type:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 13

    If \c{-prefix} is outside the build directory, you need to install
    the library, demos, examples, tools, and tutorials in the appropriate
    place. To do this, type:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 14

    as root, if neccessary (note that this requires that you have administrator access
    to your machine).

    There is a potential race condition when running make install with multiple
    jobs. It is best to only run one make job (-j1) for the install.

    \bold{Note:} If you later need to reconfigure and rebuild Qt from the
    same location, ensure that all traces of the previous configuration are
    removed by entering the build directory and typing \c{make confclean}
    before running \c configure again.

\o  Environment variables

    In order to use Qt, some environment variables need to be
    extended.

\snippet doc/src/snippets/code/doc_src_installation.qdoc 15

    This is done like this:

    In \c{.profile} (if your shell is bash), add the following lines:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 16

    In \c{.login} (in case your shell is csh or tcsh), add the following line:

\snippet doc/src/snippets/code/doc_src_installation.qdoc 17

    If you use a different shell, please modify your environment
    variables accordingly.

\o  That's all. Qt is now installed.

\ingroup qtce
\brief How to install Qt on Windows CE.
\previouspage Installation

\note Qt for Windows CE has some requirements that are given in more detail
in the \l{Qt for Windows CE Requirements} document.

\list 1
    \o  Uncompress the files into the directory you want to install Qt into;
        e.g., \c{C:\Qt\4.6.1}.

        \note The install path must not contain any spaces.

    \o  Environment variables

        In order to build and use Qt, the \c PATH environment variable needs
        to be extended:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 18

        This is done by adding \c{c:\Qt\4.6.1\bin} to the \c PATH variable.

        For newer versions of Windows, \c PATH can be extended through
        "Control Panel->System->Advanced->Environment variables" and for
        older versions by editing \c{c:\autoexec.bat}.

        Make sure the enviroment variables for your compiler are set.
        Visual Studio includes \c{vcvars32.bat} for that purpose - or simply
        use the "Visual Studio Command Prompt" from the Start menu.

    \o  Configuring Qt

        To configure Qt for Windows Mobile 5.0 for Pocket PC, type the
        following:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 19

        If you want to configure Qt for another platform or with other
        options, type \c{configure -help} to get a list of all available
        options. See the \c README file for the list of supported platforms.


    \o Building Qt

        Now, to build Qt you first have to update your \c PATH, \c INCLUDE
        and \c LIB paths to point to the correct resources for your target
        platforms. For a default installation of the Windows Mobile 5.0
        Pocket PC SDK, this is done with the following commands:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 20

        We provide a convenience script for this purpose, called \c{setcepaths}.
        Simply type:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 21

        Then to build Qt type:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 22

        \o  That's all. Qt is now installed.

        To get started with Qt, you can check out the examples found in the
        \c{examples} directory of your Qt installation. The documentation can
        be found in \c{doc\html}.

        \bold{Remember:} If you reconfigure Qt for a different platform,
        make sure you start with a new clean console to get rid of the
        platform dependent include directories.

/*! \page install-Symbian-installer.html
\title Installing Qt on the Symbian platform from a Binary Package
\ingroup qtsymbian
\brief How to install Qt on the Symbian platform from a binary package.

\note Qt for the Symbian platform has some requirements that are given in more detail
in the \l{Qt for the Symbian platform Requirements} document.

\list 1

    \o  Install Qt

        Run \c{qt-symbian-opensource-4.6.1.exe} and follow the instructions.

        \note Qt must be installed on the same drive as the Symbian SDK you are
        using, and the install path must not contain any spaces.

    \o  Install Qt into a device

        To run Qt applications on a device, \c{qt_installer.sis} found
        in the Qt installation directory must be first installed into the device.
        \c{Qt_installer.sis} contains Qt libraries and Open C libraries all in one
        convenient package.
        Begin installation by connecting your device via USB cable to a computer that
        has the \l{http://www.nokia.com/pcsuite}{Nokia PC Suite} installed.
        On the device, select "PC Suite mode". In Windows Explorer right click
        on the \c{qt_installer.sis} file, select "Install with Nokia Application
        Installer" and follow the instructions.

    \o  Running Qt demos

        We've included a subset of the Qt demos in this package for you
        to try out. An excellent starting point is the "fluidlauncher"
        demo.

        To run the demo on a real device, install \c{fluidlauncher.sis}
        found in the Qt installation directory to a device that already has Qt installed.
        After installation, you can find fluidlauncher in the applications folder of the device.

        To run the demos and examples on the emulator, you need to build them first.
        Open the "Qt for the Symbian platform Command Prompt" from the Start menu and type:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 25

        To run the demos on the emulator simply navigate to the directory of the demo
        you want to see and run:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 27

        For more information about building and running Qt programs on the
Symbian platform,
        see \l{The Symbian platform - Introduction to Qt}.

    We hope you will enjoy using Qt.

/*! \page install-Symbian.html
\title Installing Qt on the Symbian platform
\ingroup installation
\ingroup qtsymbian
\brief How to install Qt on the Symbian platform.

\note Qt for the Symbian platform has some requirements that are given in more detail
in the \l{Qt for the Symbian platform Requirements} document.

\note \bold {This document describes how to install and configure Qt for
the Symbian platform from scratch.
If you are using pre-built binaries, follow the instructions given in the
\l{Installing Qt on the Symbian platform from a Binary Package} document.}

\list 1

    \o  Setup the development environment

        Make sure your Symbian development environment is correctly installed and
        patched as explained in the \l{Qt for the Symbian platform Requirements} document.

        After you have finished the Symbian development environment setup, it is good
        to verify that environment is functional for example by compiling one
        of the pure Symbian examples for both emulator and HW. This can be done from
        command prompt as follows:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 32

        If all steps pass without errors your Symbian development environment is
        very likely installed correctly.

    \o  Install Qt

        Uncompress the \l{http://qt.nokia.com/downloads}{downloaded} source package into the
        directory you want Qt installed, e.g. \c{C:\Qt\4.6.1}.

        \note Qt must be installed on the same drive as the Symbian SDK you are
        using, and the install path must not contain any spaces.

    \o  Environment variables

        In order to build and use Qt, the \c PATH environment variable needs
        to be extended:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 18

        This is done by adding \c{c:\Qt\4.6.1\bin} to the \c PATH variable.

        On Windows the PATH can be extended by navigating to
        "Control Panel->System->Advanced->Environment variables".

        In addition, you must configure the environment for use with the Symbian
        emulator. This is done by locating the Carbide.c++ submenu on the Start
        menu, and choosing "Configure environment for WINSCW command line".

        If you are planning to use abld (the default build system that comes with the S60 SDK)
        to build Qt, you will also need to set the following environment variable:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 33

        This is not necessary for other applications, only when building Qt.

    \o  Configure Qt

        To configure Qt for the Symbian platform, do:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 23
        to build the tools using MinGW, and the libraries using abld.
        or
        \snippet doc/src/snippets/code/doc_src_installation.qdoc 31
        to build the tools using MinGW, and the libraries using SBSv2.

        SBSv2 (also known as \l{http://developer.symbian.org/wiki/index.php/Introduction_to_RAPTOR} {Raptor})
        is a next-generation Symbian build system. SBSv2 is not officially
        supported by any of the S60 SDKs currently available from Forum Nokia.

    \o  Build Qt

        To build Qt for the emulator, type:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 24

        To build Qt for the device, type:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 28

        Congratulations, Qt is now ready to use.

    \o  Running Qt demos

        We've included a subset of the Qt demos in this package for you
        to try out. An excellent starting point is the "fluidlauncher"
        demo. To run the demo on a real device, you first have to install
        the Qt libraries on the device:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 29

        \note You will need to supply certificate that allows installation
        of binaries with "All -Tcb" capability to your device.

        Similarly, install fluidlauncher to the device:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 30

        This will create a self-signed \c fluidlauncher_armv5_urel.sis and
        install it to your device.

        To run the demos on the emulator simply navigate to the directory of the demo
        you want to see and run:

        \snippet doc/src/snippets/code/doc_src_installation.qdoc 27

        For more information about building and running Qt programs on the
        Symbian platform, see \l{The Symbian platform - Introduction to Qt}.

    \section1 OpenSSL (version 0.9.7 or later)

    Support for \l{SSL}{Secure Sockets Layer (SSL)} communication is provided by the
    \l{OpenSSL Toolkit}, which must be obtained separately. More information about
    enabling SSL support can be found in the \l{Secure Sockets Layer (SSL) Classes}
    document.

    \section1 Platform-Specific Requirements

    Each platform has its own specific set of dependencies. Please see the relevant

    \note You must compile with XRender support to get alpha transparency
    support for pixmaps and images.

    Development packages for these libraries contain header files that are used
    when building Qt from its source code. On Debian-based GNU/Linux systems,
    for example, we recommend that you install the following development
    packages:

    \list
    \o libfontconfig1-dev
    \o libfreetype6-dev
    \o libx11-dev
    \o libxcursor-dev
    \o libxext-dev
    \o libxfixes-dev
    \o libxft-dev
    \o libxi-dev
    \o libxrandr-dev
    \o libxrender-dev
    \endlist

    Some of these packages depend on others in this list, so installing one
    may cause others to be automatically installed. Other distributions may
    provide system packages with similar names.

    \section1 OpenGL Dependencies

    The configure script will autodetect if OpenGL headers and libraries are
    installed on your system, and if so, it will include the QtOpenGL module
    in the Qt library.

    If your OpenGL headers or libraries are placed in a non-standard directory,
    you may need to change the \c QMAKE_INCDIR_OPENGL and/or
    \c QMAKE_LIBDIR_OPENGL in the config file for your system.

    The QGL documentation assumes that you are familiar with OpenGL
    programming. If you're new to the subject a good starting point is
    \l{http://www.opengl.org/}.

    \section1 Phonon Dependencies

    As described in the \l{Phonon Overview}, Phonon uses the GStreamer multimedia
    framework as the backend for audio and video playback on X11. The minimum required
    version of GStreamer is 0.10.

    To build Phonon, you need the GStreamer library, base plugins, and development
    files for your system. The package names for GStreamer vary between Linux
    distributions; try searching for \c gstreamer or \c libgstreamer in your
    distribution's package repository to find suitable packages.

    \section1 Building Qt for Embedded Linux with uclibc

    If you intend to include the QtWebKit module in your Qt build then you should
    use version \bold{uClibc 0.9.29 or greater} as that is the earliest version
    with sufficient pthread support.

    \section1 Memory Requirements

    The memory and storage requirements for Qt for Embedded Linux depend on a
    an variety of different factors, including the target architecture and the
    features enabled in the Qt build.

    The following table shows typical library sizes for the most common Qt
    libraries on different architectures, built in release mode with different
    feature profiles.
