INSTALLING Qt
|
|
|

|
|
|
14 |
On Windows and Mac OS X, if you want to install the precompiled binary
|
|
|
15 |
packages, simply launch the package and follow the instructions in the
|
|
|
16 |
installation wizard.
|
|
|
17 |
|
|
|
18 |
On Mac OS X, the binary package requires Mac OS X 10.4.x (Tiger) or
|
|
|
19 |
later and GCC 4.0.1 to develop applications. Its applications will run
|
|
|
20 |
on Mac OS X 10.3.9 and above.
|
|
|
21 |
|
|
|
22 |
If you have a source package (a .tar.gz, .tar.bz2, or .zip file),
|
|
|
23 |
follow the instructions in the INSTALL file.

|
|
|
38 |
type 'assistant' on the command line or use the Start menu. On Mac OS
|
|

HOW TO REPORT A BUG
|
|
|
63 |
|
|
|
64 |
If you think you have found a bug in Qt, we would like to hear about
|
|
|
65 |
it so that we can fix it. Before reporting a bug, please check
|
|
|
66 |
http://qt.nokia.com/developer/faqs/ and
|
|
|
67 |
http://qt.nokia.com/products/appdev/platform/platforms/ to see if
|
|
|
68 |
the issue is already known.
|
|
|
69 |
|
|
|
70 |
Always include the following information in your bug report: the name
|
|
|
71 |
and version number of your compiler; the name and version number of
|
|
|
72 |
your operating system; the version of Qt you are using, and what
|
|
|
73 |
configure options it was compiled with.
|
|
|
74 |
|
|
|
75 |
If the problem you are reporting is only visible at run-time, try to
|
|
|
76 |
create a small test program that shows the problem when run. Often,
|
|
|
77 |
such a program can be created with some minor changes to one of the
|
|
|
78 |
many example programs in Qt's examples directory. Please submit the
|
|
|
79 |
bug report using the Task Tracker on the Qt website:

|
