Qt for Windows - Specific Issues
This page contains information about Qt for Windows.
Targeting XP with Visual Studio 2012 and later
Visual Studio 2012 and later do not support building for Windows XP out of the box. However, support for targeting XP was added in an update of Visual Studio 2012. This works also with Visual Studio 2013.
You need to compile Qt from sources. Set up an environment on the command line, for example
"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat" set PATH=C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Bin;%PATH% set INCLUDE=C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include;%INCLUDE% set LIB=C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include;%LIB% set CL=/D_USING_V110_SDK71_
configure with the
-target xp argument:
configure -target xp <other arguments> nmake
Also compile your own application in the above environment if compiling on the command line. If you use Visual Studio, set the
v110_xp toolset in the project's property pages.
Installing Qt into a directory with spaces, for example, C:\Program Files, may cause linker errors like the following:
c:\program.obj not found
Install Qt into a sub-directory without spaces to avoid this problem.
Possible GL conflict
There is a known issue when running Microsoft NetMeeting, Lotus SameTime, and other applications that require screen grabbing while direct rendering is enabled. Other GL-applications may not work as expected, unless direct rendering is disabled.
Intel C++ Compiler (Windows, Altix)
Qt has been tested successfully with:
- Windows - Intel(R) C++ Compiler for 32-bit applications, Version 9.1.040.
- Altix - Intel(R) C++ Itanium(R) Compiler for Itanium(R)-based applications Version 8.1 Build 20050406 Package ID: l_cc_pc_8.1.030
The Visual C++ Linker doesn't understand filenames with spaces (for example, C:\Program files\Qt\) so you will have to move it to another place, or explicitly set the path yourself.
If you are experiencing strange problems with using special flags that modify the alignment of structure and union members (such as
/Zp2) then you will need to recompile Qt with the flags set for the application as well.
Visual Studio 2010 should be updated to Service Pack 1. Otherwise, a problem when compiling Qt for 64-bit in release mode may occur (visit http://support.microsoft.com/kb/2280741).
