As i said earlier, there is no Arm option under Active Solution Platform > new. any idea ?

You are in the manager for .net there, which is CLR and does not need to be set to arm

are you willing to explain about that ?, where do i know my application can be used on windows RT ?, thanks

.net applications are platform independent as they are built on a common language runtime (CLR) which is interpreted at runtime and converted into machine code.

Silverlight apps are also CLR but they will not run on Windows RT due to it not being present.

It is fairly difficult to "guess" which of the CLR types you are trying to compile without knowing more about the project, but if it is .net converting it to pure .net 4.5 should be enough providing it isn't WPF.

Where the ARM libs and compiler come in is for C/C++ projects as these turn out native executables.

I just created a new project Windows Forms Application, and guess what, I'm able to run it on windows rt. unfortunately i have been working this two days on WPF project. what a waste. is there any workaround to compile WPF project for Windows RT ?

Thanks lilstevie.

I'm getting the following when compliling (linking) arm console and gui apps
>msvcrt.lib(wcrtexe.obj) : error LNK2001: unresolved external symbol __imp_EncodePointer

Tried adding msvcrt.lib into configuration, Linker, Input, Additional Dependancies -- no help
(update - and kernel32.lib is already in there)

msvcrt.lib was already in the lib\arm\ directory and I didn't overwrite it

Update
My cmd line building of cmd line apps (using /D _ARM_WINAPI_PARTITION_DESKTOP_SDK_AVAILABLE) that used to work, has also stopped working
(cmd line building of gui apps always gave me issues with lib's etc and I'm still working on that)

Taking the new lib's out of ..\lib\arm and the build from cmd line works again

Looks like I got some lib in there that adversely affects both cmd line and VS gui builds

Now fixed (cant remember exactly what new lib I had to remove, it was in amongst all the l*.lib and m*.lib ones)

Update3
If VS fails at the link stage with "incorrect MSPDB110.DLL version", just temporarily delete (rename) the MSPDB110.DLL in the bin\x86_arm directory

According to http://msdn.microsoft.com/en-us/library/bb432254(VS.85).aspx, EncodePointer is in kernel32.lib. Typically this library is included by default, I believe, but for ARM projects it must be added manually under Project Properties -> Linker -> Input.

In the future, when you encounter such messages, just go look on MSDN for the .LIB that you need to use.

Thanks. Also, one more question. As you may already know a person can build there own arm base device to test code on. I wish to do this for the rt. Is there a list of requirements for building for rt. ( the device could be made with Adriano and arm. How do a attain a development copy of rt or rt embedded?

RT is only available on OEM devices (retail tablets, Surface, Vivo Tab, etc...)

Yeah, it's not even listed in MSDN subscriber section.

You could also be lazy and put all of your Windows RT libs in a folder and just add 'c:\path\to\folder\*.lib' as a library and it'll import all of them. That's what I've been doing.

Hi, I'm trying to recompile ScummVM for Windows RT and everything seems to go well, after changing solution platform and configuration building goes well, but at 99% there is an error:

Code:

Error	2	error MSB6006: "cmd.exe" exited with code 9009.	C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V110\Microsoft.CppCommon.targets	172	5	scummvm

Could anyone help?

EDIT: Possibly I found source of a problem:

Code:

31>------ Rebuild All started: Project: scummvm, Configuration: Release ARM ------
31>  Performing Custom Build Tools
31>  'nasm.exe' is not recognized as an internal or external command,
31>  operable program or batch file.

========== Rebuild All: 30 succeeded, 1 failed, 0 skipped ==========

From ScummVM dev wiki:

"Additional tools

You will need to download and install nasm which is used for assembler versions of our scalers."

Must find a way to cut it from source.

EDIT: Ok, there were 2 scalers written in ASM, I deleted those so nasm is no longer needed, also scummvm make use of libmad - MPEG audio decoder library which has some inline assembly so I was forced to get rid of it. Still there are 6 errors I can't resolve:

'FORBIDDEN_look_at_common_forbidden_h_for_more_info'

Have you looked at common_forbidden.h for more info?

These errors usually happen when some header file has ifdef blocks for x86 and x64 and an a final else block that errors. When you compile for arm, you hit that else block. You'll need to figure out the "right" way to do whatever they're doing for arm.

setjump/longjump usually do crap with the pc and stack pointers, so it will be cpu specific. google for arm setjmp.h to get some ideas of what you'll have to do to make it work for arm...

Also, unless those assembly files were merely optional optimizations for C/C++ code that you can use instead, simply "removing" chunks of assembly is likely to break things. You havne't gotten to the linker, yet; it may conlain of missing program entry points when you do unless you have substitutes for those assembly functions.

Those assembly lines were used by two scalers. Also there is nice tool in scummvm source that you can use to customize project, example:

Still, those setjmp errors, specifically in line:

Code:

_CRTIMP __declspec(noreturn) void __cdecl longjmp(_In_ jmp_buf _Buf, _In_ int _Value) throw(...);

It's beyond me so I'm forced to give up.

libmad builds fine - it just needs to be built with /D FPM_DEFAULT or /D FPM_64BIT instead of any other potential option. scummvm probably has a config.h for libmad that has:

#define FPM_INTEL

in it (or similar in the C/C++ macro list in VS), which causes x86 assembler to be used in the fixed-point routines.

Good to know. BTW, setjmp errors are gone - adding "#define FORBIDDEN_SYMBOL_ALLOW_ALL" at the beginning of backends/saves/windows/windows-saves.cpp solved this problem. Still I was expecting it to be easier job so don't know if I will handle this.

EDIT: Building went ok, now there are errors during code generation. Could anybody look at this?:

Code:

EDIT2: Already figured it out. So the very first Windows RT build of ScummVM is ready, much still have to be done but that's some start.

There is no MFC library for ARM in Visual Studio, though DLL is present on the device.
We can't use dll2lib to create our own import library from mfc110u.dll as it exports only ordinals, but I was managed to recompile MFC from sources as a static library. As MS provided incomplete sources - some features are not present, for example using OLE controls and MFC controls embedded in dialogs designed in visual studio dialog editor. Creating those controls dynamically would work fine.
More information is here.
LIB sizes are huge (157 Mb debug and 1.2 Gb release builds) as I have not stripped the debug information. Don't be afraid of that - the produced EXE files would be small.
You can recompile MFC yourself like I did, or download LIBs here: http://www.multiupload.nl/FJEYPW5M26
Compressed with 7Zip as it gave the smallest archive size.

For installation - uncompress them into: "\Program Files (x86)\Microsoft Visual Studio 11.0\VC\atlmfc\lib\arm\" directory, add "#define _AFX_NO_MFC_CONTROLS_IN_DIALOGS" to your stdafx.h and select "use MFC in static library" in your project settings.

Good idea mamaich, I haven't had much time lately, but I was able to get a mfc .def with most of the named ordinals by using libtool and dumpbin with the .pdb in the directory. If dumpbin detects a .pdb file, it uses the pdb hints to generate the .def. Microsoft SymServer has the pdb for arm.

The problem I had is with the mfc static part, maybe you could figure that out and we'll have MFC

Unfortunately I don't have time for that - spending all time on the emulator project.
But it should not be too difficult. After looking at static x86 part - you can see the needed files:

Code:

rawdllmainproxy.obj
stdafx.obj
nolib.obj
appmodul.obj
dumpstak.obj
oleexp.obj
sockexp.obj
dllmodul.obj
dllmodulx.obj

All files except for the last one are present. You need to reconstruct the last one manually looking at the dumpbin output. Or maybe we could ask in microsoft forums for this file?

Ugh... working on porting Free Download Manager, and it's demanding MFC and ATL, and in particular nafxcw.lib. I don't know MFC very well at all; not sure what it would take to get that file but without it I'm not able to port the program. I've gotten almost all the components ported, but the actual EXE is MFC based.
