Qt FAQ about how to install Qt Creator under Cygwin.

 

According to [2] this is not possible. All approaches described below fail.

 

 

 

 

 

Failed approach 1:

 

Qt Creator is installed following the steps described by [1].

The following alternative strategies fail:

  • Trying to do './configure' and 'make' using Qt-everywhere-opensource-src-4.7.0 (a newer version as used in [1])
  • Trying to follow the steps of [1] using Qt-everywhere-opensource-src-4.7.0 (a newer version as used in [1])
  • After 'make sub-tools-bootstrap sub-moc sub-rcc sub-uic sub-corelib sub-gui' type 'make' (results in the error UnicodeQt4.h:197: error: call of overloaded 'toLower(UChar32&)' is ambiguous)

 

In the folder ~/Projects/Tools/ToolTestBinaryNewickVector, I entered the command:

qmake-qt3

 

resulting in:

 

QMAKESPEC has not been set, so configuration cannot be deduced. Error processing project file: /home/richel/Projects/Tools/ToolTestBinaryNewickVector/ ToolTestBinaryNewickVector.pro

 

The following command did not do anything either:

 

set QMAKESPEC

 

 

 

 

 

Failed approach 2: Use the Linux Qt SDK under Cygwin

 

From the Qt homepage, download the Qt SDK for Linux/X11 32-bit.

 

In the folder where the Qt installer is located, type:

 

chmod u+x qt-sdk-linux-x86-opensource-2010.05.bin ./qt-sdk-linux-x86-opensource-2010.05.bin

 

Result:

 

cannot execute binary file

 

 

 

 

 

Failed approach 3: Use the Windows Qt SDK under Cygwin

 

From the Qt homepage, download the Qt SDK for windows.

 

Then, from the terminal

 

run qt-sdk-win-opensource-2010.05.exe

 

The Qt Creator setup starts, then showing an NSIS error.

    Question: Do you support using Qt in the Cygwin shell on Windows? Answer: We don't support the Cygwin shell with Qt, mainly because Cygwin uses different directory separators than the Windows ones, therefore our apps are not likely to work correctly. You should use the cmd shell instead.
