Compiling ScummVM for Windows RT(ARM)

[bartekxyz]

Hi, as you might know, Windows RT allows only Windows Store apps to be used, desktop environment is locked. But with recent jailbreak tool people can run unsigned exe files in desktop. So I tried recompiling ScummVM in VS11 for ARM and building goes well but at 99% there is an error:

Code: Select all

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

Here is output:

Code: Select all

It looks like nasm is source of a problem. And there is my question: Can it be turned off? Nasm is x86 tool, my target platform is ARM.

Run the create_project tool with the parameter --disable-nasm. Check its help (via. --help) for more info.

Did it other way - cutting few lines in source. But still there are six errors during building scummvm solution(game engines build just fine). Those errors are:

Possibly not related to scummvmm source.

I'm not sure what kind of modifications you did to the source. As for setjmp, perhaps it's used in LUA in the sword25 engine? Try excluding the sword2 engine from compilation, via --disable-sword25

That error message is not really helpful, since it doesn't reveal from which file inside ScummVM setjmp.h is included. So a more detailed log would be helpful here.

About nasm: I think the problem is that you probably created the ARM configuration out of the x86 configuration. It has special custom build tool setups for NASM. One option would be to disable nasm via the command line option md5 proposed. Another option would be to use the amd64 (or x64 as it's called in MSVC) configuration as a base for your ARM configuration. An even better option would be to add support to create_project to create an ARM configuration. Removing code isn't really a solution, if you want to get this upstream.

Ok, I used create_project.exe to disable nasm, libmad(there is no way to use this library in Windows RT yet as it contains inline assembly - x86 one). I have also disabled sword25 engine but still there are the same setjmp errors. And there is line in setjmp.h which contains all six errors:

Code: Select all

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

Disabling Sword25 probably did not disable the offending code inside the shared ScummVM code. But I would say the chances that would happen have been pretty low anyway.

libmad should work fine on ARM systems. You will probably need to fiddle with the MSVC project configuration of libmad too.

And there is line in setjmp.h which contains all six errors:

Code: Select all

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

Yes, that's expected to happen when you include setjmp.h after common/scummsys.h is included. The question here is: Which file of ScummVM is being compiled when you get that error?

Here is a whole build output so you can see where exactly it fails:

You'll probably need to add a

Code: Select all

#define FORBIDDEN_SYMBOL_ALLOW_ALL

before

Code: Select all

#include "common/scummsys.h"

EDIT: Just in case it isn't clear in which file, it should be: backends/saves/windows/windows-saves.cpp

Building went ok, but there are still errors during code generation:

That could be related to different runtime library setups used when compiling the libraries/ScummVM.

I just had to tell linker to ignore default MSVCRT.lib, so first Windows RT ScummVM version is built. Now I need to force disabled dependencies to work

[md5]

Does that binary work? Cause ignoring MSVCRT might lead to undesirable results...

Yes, it works, I'm playing The Curse Of Monkey Island on my Surface RT right now.

[grunger106]

Cool! Great work!
When this gets polished up any chance it will be submitted to the store?
I know you can run unsigned code at the moment, but this may change.....
Emulators are allowed, snes8x and the Atari 7800 ones are there already.
