ARM support

Motivation

Windows apps are mostly compiled for x86 and they won't run on ARM with bare Wine, likewise ARM applications won't run on x86(_64) with bare Wine, so this is not our motivation.

The original Motivation was to be able to run winelib-apps on ARM, that even was before it got public that win8 will run on ARM devices. Meanwhile we support these new ARM PEs for win8!

Status

  • Yes, It works! (TM)
  • Running win8 ARM PEs also works.
  • Already ported Putty to ARM as winelib application.
  • First patch was September 18. 2009, final patchset sent September 18. 2010 and they got in Wine-1.3.4
  • Wine on ARM already get's packaged by Maemo, Fedora and openSUSE.
  • Good debugger/disassembler support.
  • Relay tracing.
  • Relocation.
  • Linux Kernel patched upstream for running Windows RT applications (Bug 31322).

Todo

How to help

  • Fix compiler warnings.
  • Run winetest and report your results.
  • Fix test failures or analyse them, see below.
  • Report bugs with winelib or Windows RT applications.
  • Write tests for missing functions.

Compiling

Toolchains:

wine-1.3.4 - wine-1.5.4

e.g. crosscompiling per Scratchbox (An ARM mode crti.o is expected)

wine-1.5.4 - wine-1.5.7

Use the Linaro toolchain (A Thumb mode crti.o is expected (Bug 30134))

wine-1.5.8 and all later versions

Every toolchain with Thumb support should work as we are independent from the crti.o mode now

Compiling on the ARM Device is recommended:

../configure && make

Anyway here is a crosscompiling example:

../configure --host=arm-linux-gnueabihf host_alias=arm-linux-gnueabihf --with-wine-tools=../path/to/your/native/wine/build && make

Maybe you also should append something like:

CFLAGS="-mcpu=yourcpu -g -O2" LDFLAGS="-mcpu=yourcpu"

Fixme/Todo: Compiling inside a chroot

Running Windows RT Applications

You can find a list of such ported applications at forum.xda-developers.com. To run them you'll need a recent Wine and a Linux Kernel with the tpidrurw patch, it's included since Kernel 3.11-rc1. When you're unsure if the Kernel you are using supports it, you can clone, make and run tpidrurw-test, it'll tell you if your Kernel is suitable.

Running Windows CE Applications

That's still pre-alpha/proof-of-concept and not part of official Wine, don't expect any success. WineCE can be found at github.

Running Windows/x86 Applications

Actually there is a bug in qemu, so it can't work without a patch (qemu-i386-user on ARM host: wine hangs).

This configuration is not supported, but you'll be able to run some Applications. Don't ask for support on winehq.org, but be free to read I got Wine/x86 1.5.11 to run on Linux/ARM with qemu!.

./configure --target-list=i386-linux-user --extra-cflags=-marm && make
  • copy Wine/x86 with all needed libraries from your desktop to the corresponding /usr/gnemul/qemu-i386/* folders except wine-preloader (it won't work)
  • as root run

echo ':i386:M::\x7fELF\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x03:\xff\xff\xff\xff\xff\xfe\xfe\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfb\xff\xff:/path/to/patched/qemu/i386-linux-user/qemu-i386:' >/proc/sys/fs/binfmt_misc/register
echo ':DOSWin:M::MZ::/usr/gnemul/qemu-i386/usr/bin/wine:' >/proc/sys/fs/binfmt_misc/register
  • create a wineprefix on your desktop with

WINEARCH=win32 WINEPREFIX=~/.winex86 wine wineboot
  • copy it from your desktop to your home folder
  • run Wine/x86 with something like /path/to/patched/qemu/i386-linux-user/qemu-i386 /usr/gnemul/qemu-i386/usr/bin/wine winecfg

Remember: This configuration is not supported. Don't ask for support on winehq.org.

Analyzed Test Failures

  • msvcr100:msvcr100
    • softfloat vs. hardfloat
  • user32:class
    • per dissonant compile time checks the testsuite expects the x86 value for cbWndExtra, whereas the code uses the pointer size
  • vbscript:run
