| 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"

|

|

| 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.

|
---|
| 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.
