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\&.
Documentation
==========================
Qwt includes a class documentation, that is available in various formats:
- Html files
- PDF document
- Qt Compressed Help (*\&.qch ) for the Qt assistant or creator\&.
You can load it 'Edit Preferences' -> 'Documentation' -> 'Add\&.\&.\&.'
- Man pages ( UNIX only )
A) Unix Qt3/Qt4
==========================
qmake qwt\&.pro
make
make install
If you have installed a shared library it's path has to be known to
the run-time linker of your operating system\&. On Linux systems read
'man ldconfig' ( or google for it )\&. Another option is to use
the LD_LIBRARY_PATH (on some systems LIBPATH is used instead, on MacOSX
it is called DYLD_LIBRARY_PATH) environment variable\&.
If you only want to check the Qwt examples without installing something,
you can set the LD_LIBRARY_PATH to the lib directory
of your local build\&.
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
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
nmake 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
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'
When you have built a Qwt DLL you need to add the following
define to your compiler flags: QWT_DLL\&.
Windows doesn't like mixing of debug and release binaries\&. Most
of the problems with using the Qwt designer plugin are because
of trying to load a Qwt debug library into a designer release
executable\&.
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
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 examples\&.pro
make
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 in UNIX or in the
Windows Shell - or at least it should:
because of a bug in Qt 4\&.3\&.0 you always have to do a 'qmake \-r'\&.
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
C1-C3)
When you have built a Qwt DLL you need to add QWT_DLL to your compiler
flags\&. If you are using qmake for your own builds this done by adding
the following line to your profile: 'DEFINES += QWT_DLL'\&.
Windows doesn't like mixing of debug and release binaries\&. Most
of the problems with using the Qwt designer plugin are because
of trying to load a Qwt debug library into a designer release
executable\&.
D) MacOSX
Well, the Mac is only another Unix system\&. So read the instructions in A)\&.
In the recent Qt4 releases the default target of qmake is to generate
XCode project files instead of makefiles\&. So you might need to do the
following:
qmake \-spec macx-g++ qwt\&.pro
\&.\&.\&.
E) Qt Embedded
--------
I only tested Qwt with Qt Embedded 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\&.
F) Symbian
--------
I never tried this platform myself\&.
Good luck !
