To do this, give the "-a" option when you + run the "unzip' command. + + \o If you fail to supply the "-a" option when unzipping the package, you + will see the following error message when you attempt to execute the + configure command: + "bash: ./configure: /bin/sh^M: bad interpreter: No such file or directory" + + \endlist + + \section2 Installing on Mac OS X 10.6 "Snow Leopard" + + \list + + \o Performing a new install of the Qt 4.6 beta on Snow Leopard + triggers a bug in the installer that causes the install to fail. + Updating an existing Qt installation works fine. + + \o There are two workarounds, either disable spotlight for the target + drive during the install, or do a custom install where you deselect + documentation and examples. Run the installer again as a full + install to get the documentation and examples installed. + + \endlist + + \section1 Issues with Third Party Software + + \section2 X11 + + \list + \o There is a bug in the 169.xx NVIDIA drivers on certain GeForce 8 series + cards that is triggered by the OpenGL paint engine when using QPainter + on a QGLWidget to draw paths and polygons. Some other painting + operations that end up in the path fallback are affected as well. The + bug causes the whole X server to repeatedly hang for several seconds at + a time. + \o There is an issue with NVIDIA's 9xxx driver series on X11 that causes a + crash in cases where there are several \l{QGLContext}s and the extended + composition modes are used (the composition modes between and including + QPainter::CompositionMode_Multiply and + QPainter::CompositionMode_Exclusion). This affects the composition mode + demo in Qt 4.5, for example. The crash does not occur in newer versions + of the drivers. + \endlist + + \section2 Windows + + \list + + \o When using version 6.14.11.6921 of the NVIDIA drivers for the GeForce + 6600 GT under Windows XP, Qt applications which use drag and drop will + display reduced size drag and drop icons when run alongside + applications that use OpenGL. This problem can be worked around by + reducing the level of graphics acceleration provided by the driver, or + by disabling hardware acceleration completely. + + \o With NVIDIA GeForce 7950 GT (driver version 6.14.11.7824), a fullscreen + QGLWidget flickers when child widgets are shown/hidden. The workaround + for this is to use \l{QWidget::}{setGeometry()} with a width/height 1 + pixel bigger than your geometry and call \l{QWidget::}{show()}. + + \o A bug in the Firebird database can cause an application to crash when + \c{fbembed.dll} is unloaded. The bug is fixed in version 2.5. + + \o On Windows 7, resizing windows is slower than on Vista/Xp. This is because + the gesture initialization process (required for native gesture support) + currently calls winId() on widgets, which causes whole widget hierarchies + to use native window handles. This slows down resizing. + + \o Compile errors with Intel C++ Compiler.\br + There seems to be a bug in the Intel compiler with respect to + over-agressive inlining of code. + The problem will manifest itself during the link phase of QtGui where + it fails with the error that it cannot find QObjectData::~QObjectData(). + See \l{http://bugreports.qt.nokia.com/browse/QTBUG-5145} for updates on this + bug. + Also, due to some bugs in WebKit, the QtScript and QtWebKit modules + will not compile. + See \l{http://bugreports.qt.nokia.com/browse/QTBUG-6297} for a + workaround for QtScript. + + \endlist + + \section2 Mac OS X + + \list + + \o If a sheet is opened for a given window, clicking the title bar of that + window will cause it to flash. This behavior has been reported to Apple + (bug number 5827676). + + \endlist + + \section2 Symbian + + \list + \o Check known issues for Symbian at + \l{http://qt.gitorious.org/qt/pages/QtKnownIssues} {Known Issues Wiki}. + \endlist +*/
