58 \section1 Installation Issues
59
60 \section2 Installing the Source Package on Unix systems
61
62 \list
63
64 \o If you download a Zip source package, you will need to convert
65 Windows-style line endings (CR/LF) to Unix-style line-endings (LF) when
66 you uncompress the package. To do this, give the "-a" option when you
67 run the "unzip' command.
68
69 \o If you fail to supply the "-a" option when unzipping the package, you
70 will see the following error message when you attempt to execute the
71 configure command:
72 "bash: ./configure: /bin/sh^M: bad interpreter: No such file or directory"
73
74 \endlist
75
76 \section2 Installing on Mac OS X 10.6 "Snow Leopard"
77
78 \list
79
80 \o Performing a new install of the Qt 4.6 beta on Snow Leopard
81 triggers a bug in the installer that causes the install to fail.
82 Updating an existing Qt installation works fine.
83
84 \o There are two workarounds, either disable spotlight for the target
85 drive during the install, or do a custom install where you deselect
86 documentation and examples. Run the installer again as a full
87 install to get the documentation and examples installed.
88
89 \endlist
90
91 \section1 Issues with Third Party Software
92
93 \section2 X11
94
95 \list
96 \o There is a bug in the 169.xx NVIDIA drivers on certain GeForce 8 series
97 cards that is triggered by the OpenGL paint engine when using QPainter
98 on a QGLWidget to draw paths and polygons. Some other painting
99 operations that end up in the path fallback are affected as well. The
100 bug causes the whole X server to repeatedly hang for several seconds at
101 a time.
102 \o There is an issue with NVIDIA's 9xxx driver series on X11 that causes a
103 crash in cases where there are several \l{QGLContext}s and the extended
104 composition modes are used (the composition modes between and including
105 QPainter::CompositionMode_Multiply and
106 QPainter::CompositionMode_Exclusion). This affects the composition mode
107 demo in Qt 4.5, for example. The crash does not occur in newer versions
108 of the drivers.
