Windows

• QTBUG-27953: Installing vcredist.exe stops with unexpected exit code
  • Can be ignored if Visual C++ 2010 Redistributable Package is already installed; this happens when the version installed in the system is newer than the one provided by the installer.

• -QTBUG-27903-: Qt5 Beta2 does not register DLLs properly so that no examples can be run
  • Use Start Menu -> All programs-> Qt 5.0.0 Beta 2 -> 5.0.0-> MSVC 2010 (32/64) bit -> Qt 5.0.0 (32/64) bit for Desktop (MSVC 2010)

• -QTBUG-27893-: MaintenanceTool.exe on Windows 7 hangs while uninstalling
  • It just takes some time to finish.

• -QTBUG-27961-: Unable to recompile Qt on Windows using Installer Packages Builds
  • configure.exe is missing in the Qt Essentials sources that ship with the binary installer.
  • Work around is to create a file .gitignore, and using the top level configure.bat:
    • C:gt; touch qtbaseitignore
    • C:gt; configure.bat [options…]

• QTBUG-27980: qmake is run every time an application is compiled
  • Workaround: Edit Tools\Qt Creator\share\qtcreator\QtProject\qtcreator\qtversion.xml so that the qmake path only contains forward slashes + no double slash

• QTWEBKIT-382: MinGW: Compiling qtwebkit under MinGW, or MinGW-w64 based toolchains fails.
  • No workaround.

• QTBUG-8241: cdb debugger doesn't stop: Cannot start …terrupt.exe
  • Workaround: Rename "Tools\Qt Creator" to "Tools\QtCreator"

• QtCreator: Visual Studio C++ 2010 Express on Windows 7 64 bit does not work.
  • Install Windows SDK
  • Create an empty file called: C:Files (x86)Visual Studio 10.0\vc\bin\amd64\vcvars64.bat
  • Add the following line: CALL "C:Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" /x64

Mac OS X

  • No workaround yet.

• QTBUG-27894: Installed qtdeclarative/examples don't work
  • Example applications fail to find qml files from the application bundle. Launching content with qmlscene works.
  • Workaround: Apply this one-liner fix and rebuild the example(s).

• Installation fails with error "… can’t be opened because it is from an unidentified developer." [Mac OS X 10.7.5 and newer]
  • Right-click on the installer file, select "Open", then "Ok".
