qwtinstall - .PP
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 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 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 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 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: 'adminmsvc-qmake' To generate project files, type: 'adminmsvc-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 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 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 make -i install 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++ 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 !
