[Qemu-devel] Compiling Qemu x86_64 for windows 64 bit

Hi,

U tried compiling Qemu on windows sever 2008 64 bit using mingw64. After following the steps at betaarchive.com I managed to get a binary. It now just dies as soon as I start it. How do I debug this.

I also tried downloading the 64 bit installer from Stephan Weil website qemu.weilnetz.de but it dies too with an assertion.

Foes anyone have a working build for win64?

Thanks.
-Vikas

Stephan Weil is another person, not me. I am Stefan Weil. :-)

Which version of the installer did you try? Which assertion or failure
message did you get?
How did you start the binary.

Without more information, nobody will be able to answer your questions.

Thanks for the quick response.Sorry for the typo. It was the autocorrect :). I downloaded qemu-w64-setup-20130921.exe

When I try running

qemu-system-x86_64w.exe with an iso I get an assertion - /home/stefan/src/qemu/repo.or.cz/qemu/ar7/qemu-coroutine-lock.c, line 99
Expression : qemu_in_coroutine()

Hello,
I had the same error. I tried this binary http://lassauge.free.fr/qemu/release/Qemu-1.6.0-windows.zip
You have to copy everything in Bios to ../ so one directory up. Then it should work.

Kind regards,
Manuel

Hi again,

I downloaded the linux test image and tried booting it. I got a kernel panic the stack trace looks like this -

test_wp_bit+0x28/0x6c
start_kernel0x150/0x225
unknown_bootoption+0x0/0x1a9

Hi,
After some further testing I found that even the 32 bit binaries from Stefan fail with the same error. I tried the 32 bit binaries from by Eric Lassauge for version 1.6 and they work well. I have tried both 32 and 64 bit binaries from Stefan on 2 different environments, both failing with same errors.
When I just run the binaries with no disk image or any other options, I get a proper window with the BIOS going through all drives looking for a bootable device. Only when I have a valid executable image I get the error. Also, in case of the test linux binary I get a kernel panic on linux but qemu does not crash.
What should I do further to debug this? 
Hi Stefan,
Could you share what tools you use for the build? Any hints on what more could I try?
Thanks,Vikas

Hi Vikas,

I also get the corouting assertion when I start my precompiled QEMU
binary with an ISO image (Debian i386 netinstall).
The error can be reproduced with Wine on Linux, too.

There is no error when QEMU was configured with --enable-debug (which
disables optimisation),
nor is there an error when I just run the BIOS code (no disk, no cdrom).
This explains why I did not
notice the regression for Windows earlier.

So we have to find the first version which shows that regression, either
by testing older installers
or by running git bisect.

Cheers,
Stefan

Summary:

Latest qemu-system-i386 for Windows fails with an assertion
(qemu-coroutine-lock.c:99)
if something more complex than the BIOS is executed. It works when it is
configured with
--enable-debug. This behaviour is identical for 32 bit and 64 bit
executables and can also
be reproduced using Wine. Older versions also fail, but with SIGSEGV
instead of an assertion.

This is the result of git bisect:

402397843e20e35d6cb7c80837c7cfdb19ede591 is the first bad commit
commit 402397843e20e35d6cb7c80837c7cfdb19ede591
Author: Paolo Bonzini <pbonzini@redhat.com>
Date: Tue Feb 19 11:59:09 2013 +0100

coroutine: move pooling to common code

The coroutine pool code is duplicated between the ucontext and
sigaltstack backends, and absent from the win32 backend. But the
code can be shared easily by moving it to qemu-coroutine.c.

When I configure latest QEMU with --disable-coroutine-pool, it works!

I'll build new installers with this option until there is a bug fix
available.

Thanks for your bug report.

Thanks Stefan. Appreciate the quick response.
I tried recompiling with --enable-debug but the binaries still die without any error message. I am using mingw64 + MSYS and SDL. I would probably take the easy route and wait for you to publish the new builds :)

In my case the bios is in the same directory. In your case you can use the -L Bios option to point qemu to the Bios directory.
