Qt QtCore4 does not link with ARM target

blackbelt

I was playing around with Qt in Visual Studio 2005. I was able to run a simple application when the Target Machine was THUMB, but if I change it in ARM I get the following link error:

@ QtCore4.lib(QtCore4.dll) : fatal error LNK1112: module machine type 'THUMB' conflicts with target machine type 'ARM'@

Could help me with this?

How was the compilation of Qt libs for the ARM processor done?
What is the target OS?

I used @-xplatform wincewm60professional-msvc2005 @ . Is it wrong? The qmake says @ /MACHINE THUMB @ . Could I saftely recompile Qt change @ /MACHINE @ in @ ARM @ ?

Thank you

I am compiling using MSVC 2005 for x-compilation to WINCE5 also with an ARM processor as target. My linker options have /SUBSYSTEM:WINDOWSCE set, but no /MACHINE. So it must use the default value. That works for me. I remember coming across some statement with thumb and changed it to arm too. The result was not successful. So I am using defaults.

Where do you set /MACHINE parameter in the menu? I could not find right away.

inside:
@mkspecs/wincewm60professional-msvc2005/qmake @

and its content is:

@include(../wincewm50smart-msvc2005/qmake.conf)

CE_SDK = Windows Mobile 6 Standard SDK
CE_ARCH = ARMV4I

DEFINES -= _WIN32_WCE=0x501
DEFINES += _WIN32_WCE=0x502

Windows Mobile 6 Standard edition defines

GWES_ICONCURS=1 although there is no cursor support

DEFINES += QT_NO_CURSOR

QMAKE_LFLAGS_CONSOLE = /SUBSYSTEM:WINDOWSCE,5.02 /MACHINE:THUMB /ENTRY:mainACRTStartup
QMAKE_LFLAGS_WINDOWS = /SUBSYSTEM:WINDOWSCE,5.02 /MACHINE:THUMB
QMAKE_LFLAGS_DLL = /SUBSYSTEM:WINDOWSCE,5.02 /MACHINE:THUMB /DLL
QMAKE_LIBFLAGS = $$QMAKE_LFLAGS_WINDOWS

@

looking at the docs:

QMAKE_LFLAGS_WINDOWS: This variable contains link flags when building console programs.

So I was wandering if change in @ARM@ could help.
Thank you for your time

Frankly I do not know. I have always used the default setting for compilation of Qt for wince. The check of conf showed, as you mentioned, /MACHINE:THUMB

change in @MACHINE:THUMB@ does not help (it does not compile). Anyone could suggets any fix?
