5 http://qt.nokia.com/doc/latest/qt4-intro.html for details.
7 The Qt 4.x series is not binary compatible or source compatible with
8 the 3.x series. For more information on porting from Qt 3 to Qt 4, see
9 http://qt.nokia.com/doc/latest/porting4.html.
14 If you have a source package (a .tar.gz, or .zip file), follow the
15 instructions in the INSTALL file.
17 On Windows and Mac OS X, if you want to install the precompiled binary
18 packages, simply launch the package and follow the instructions in the
21 For Mac OS X Carbon, the binary package requires Mac OS X 10.4 (Tiger) or
22 later and GCC 4.0.1 to develop applications. Its applications will run
23 on Mac OS X 10.4 and above.
25 For Mac OS X Cocoa, the binary package requires Mac OS X 10.5 (Leopard) or
26 later and GCC 4.0.1 to develop applications. Its applications will run
27 on Mac OS X 10.5 and above.
32 Once Qt is installed, we suggest that you take a look at the demos and
33 examples to see Qt in action.
35 For desktop computers, run the Qt Examples and Demos either by
36 typing 'qtdemo' on the command line or through the desktop's Start
37 menu. On Mac OS X, you can find it in /Developers/Applications/Qt.
39 For embedded devices, launch the Qt 'fluidlauncher' demo, either through
40 the platforms filebrowser or the built in menu system.
43 REFERENCE DOCUMENTATION
45 The Qt reference documentation is available locally in Qt's doc/html
46 directory. You can use Qt Assistant to view it; to launch Assistant,
47 type 'assistant' on the command line or use the Start menu. On Mac OS
48 X, you can find it in /Developer/Applications/Qt. The latest
49 documentation is available at http://qt.nokia.com/doc/.

73 If you think you have found a bug in Qt, we would like to hear about
74 it so that we can fix it. The Qt bug tracking system is open to the
75 public at http://bugreports.qt.nokia.com/.
77 Before reporting a bug, please use the bug-tracker's search functions
78 and consult http://qt.nokia.com/developer/faqs/ to see if the issue is
81 Always include the following information in your bug report: the name
82 and version number of your compiler; the name and version number of
83 your operating system; the version of Qt you are using, and what
84 configure options it was compiled with.
86 If the problem you are reporting is only visible at run-time, try to
87 create a small test program that shows the problem when run. Often,
88 such a program can be created with some minor changes to one of the many
89 example programs in Qt's examples directory, or to the autotests that
90 are available in the public source repository on http://qt.gitorious.org/.
