64位Qt应用程序在XP 64位上崩溃（但在Win7 64位上没有崩溃）

Question

I am using Windows 7 (64-bit) to develop a Qt (5.3) application. The Visual Studio files are created by CMake. This works fine for 32-bit and 64-bit binaries for Windows 7. CMake Generator for 32-bit is Visual Studio 12 2013 , for 64-bit Visual Studio 12 2013 Win64 .

I tried to create the binaries for Windows XP, too.

I added this line to the CMakeLists.txt for the 32-bit version

SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} /SUBSYSTEM:WINDOWS,5.01")

and this line for the 64-bit version

SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} /SUBSYSTEM:WINDOWS,5.02")

I am using windeployqt for the deployment for of the QT dependencies.

After running CMake and starting the generated Visual Studio I chose the Release-Mode and changed the platform toolset to Visual Studio 2013 - Windows XP (v120_xp) .

The created 32-bit binary works fine on Windows XP 64-bit, the 64-bit binary crashes with "hello-world.exe has encountered a problem and needs to close. ..." on Windows XP-64-bit,

(EDIT: but works fine on Windows 7 64-bit).

What am I doing wrong? :(

I had a similar problem and specifying subsystem to the linker didn't fix it. However the following solution worked fine for me:

ADD_CUSTOM_COMMAND(
    TARGET my_target
    POST_BUILD
    COMMAND editbin my_target.exe /SUBSYSTEM:WINDOWS,5.01 /OSVERSION:5.1)
