    Introduction
    ============

    Qwt uses qmake to build all its components and examples.
    qmake is part of a Qt distribution.

    qmake reads project files, that contain the options and rules how to
    build a certain project. A project file ends with the suffix "*.pro".
    Files that end with the suffix "*.pri" are included by the project
    files and contain definitions, that are common for several project files.

    qwtconfig.pri is read by all project files of the Qwt package.
    So the first step is to edit qwtconfig.pri to adjust it to your
    needs.

    MathML Extension
    ================

    Qwt/Qt4 supports the MathML render engine from the Qt solutions package,
    that is only available with a commercial Qt license.

    You need a release of qtmmlwidget >= 2.1.
    Copy the files qtmmlwidget.[cpp|h] to textengines/mathml.

    A) Unix (+ MacOSX) Qt3/Qt4
    ==========================

    qmake
    make
    make install

    If you didn't enable autobuilding of the examples in qwtconfig.pri
    you have to build the examples this way:

    cd examples
    qmake
    make

    If you like to run the examples, don't forget to install the
    Qwt library/plugins or set the LD_LIBRARY_PATH to the lib directory
    of your local build. ( On some systems LIBPATH is used instead, on MacOSX
    it is called DYLD_LIBRARY_PATH. )

    B) Win32/MSVC Qt3/Qt4
    =====================

    Please read the qmake documentation how to convert
    your *.pro files into your development environment.

    F.e MSVC with nmake:
    qmake qwt.pro
    nmake

    If you didn't enable autobuilding of the examples in qwtconfig.pri
    you have to build the examples this way:

    cd examples
    nmake examples.pro
    nmake

    admin/msvc-qmake.bat helps users of Visual Studio users to
    generate makefiles or project files (.dsp for MSVC-6.0 or vcproj for
    MSVC.NET) for Qwt.

    To generate makefiles, type: "admin\msvc-qmake"
    To generate project files, type: "admin\msvc-qmake vc"

    C) Win32/MinGW Qt4
    ==================

    C1) Windows Shell

    Start a Windows Shell, where Qt4 is initialized. ( F.e. with
    "Programs->Qt by Trolltech ...->Qt 4.x.x Command Prompt" ).

    qmake qwt.pro
    make

    If you didn't enable autobuilding of the examples in qwtconfig.pri
    you have to build the examples this way:

    cd examples
    qmake examples.pro
    make
    make install

    C2) MSYS Shell Qt >= 4.3.0

    Support for the MSYS Shell has been improved in Qt 4.3.0.
    Now building Qwt from the MSYS Shell works exactly like UNIX or in the
    Windows Shell.

    C3) MSYS Shell Qt < 4.3.0

    For Qt < 4.3.0 you have to set the MINGW_IN_SHELL variable.
    make will run into errors with the subdirs target, that can be
    ignored (make -i).

    export MINGW_IN_SHELL=1;

    qmake
    make -i
    make -i install

    If you didn't enable autobuilding of the examples in qwtconfig.pri
    you have to build the examples this way:

    cd examples
    qmake examples.pro
    make -i
    make -i install

    D) MacOSX

    Well, the Mac is only another Unix system. So read the instructions in A).

    D) Qtopia Core

    I only tested Qwt with Qtopia Core in qvfb (Virtual Framebuffer Devivce)
    Emulator on my Linux box. To build Qwt for the emulator was as simple as
    for a regular Unix build.

    qmake
    make

    E) Qtopia (!= Qtopia Core)

    I once compiled the Qwt library against Qtopia 4.2.0 successfully - but
    not more. It should be possible to build and install Qwt, but it's
    not done yet.

    Good luck !
