Question : VS2008: fatal error LNK1112: module machine type 'THUMB' conflicts with target machine type 'ARM'

I'm trying to compile a simple (empty) dll project to an ARM processor device.
Project has been generated using Add New Project > Win32 SmartDevice  wizard, STANDARDSDK_500 platform selected.

When I set the compiler options to /MACHINE:ARM, linker fails with LNK1112:
module machine type 'THUMB' conflicts with target machine type 'ARM'

Configuration is: 'Debug|STANDARDSDK_500 (ARMV4I)'

I've StandardSDK500 installed.
How can I compile binaries to ARM architecture?

alexey_gusev was right. We all have past this THUMB problem. Somehow in the beginning I always conflicted with these SubSystem settings.

If you see somewhere in the project settings "THUMB" - this is the problematic place.

Anyway, the fix is in the project settings.
1. If you will open the project settings, in C/C++ section, in Advanced, please check that you have "ARM4 (/QRarch4)".
2. In Linker section on System page you may have SubSystem "Not Set" or "WindowsCE (/SUBSYSTEM:WINDOWSCE)" - better "Not Set", but if there is a problem switch to Windows CE.
3. In linker command line you may have /subsystem:windowsce,5.0, for example or whatever you need - depends on your device.

I'd install Windows Mobile 6 SDK first (probablt Pocket PC 2003 you already have).

This Standard 500 SDK was a good idea few years ago and, in fact, didn't help much. From my point of view, it is possible to use Pocket PC 2003 SDK for the same purpose.
