[Qemu-devel] QEMU News: Win32 Port

[Fabrice Bellard]

Hi,

I commited an experimental win32 port of QEMU. I did not test it yet, 
but it compiles. It is based on Kazu port, but I made heavy 
modifications to minimize the number of ifdefs and to factorize the 
"dyngen" utility code.

In order to compile it, look at 
http://www.h7.dion.ne.jp/~qemu-win/PortingTips-en.html.

Feel free to submit any patches, in particular for audio, network 
redirector or native GUI for win32.

Note that I won't accept any patch to make it compile with MSVC. You 
must use MSYS/MinGW in order to compile the win32 port of QEMU.

Fabrice.

I should not have given this URL because Cygwin is _not_ needed to 
compile QEMU. Instead use the following steps (taken from the FFmpeg 
project doc):

* Install the current versions of MSYS and MinGW from 
http://www.mingw.org/. You can find detailed installation instructions 
in the download section and the FAQ.

* Download the MinGW development library of SDL 1.2.x 
(SDL-devel-1.2.x-mingw32.tar.gz) from http://www.libsdl.org. Unpack it 
in a temporary place, and unpack the archive i386-mingw32msvc.tar.gz in 
the MinGW tool directory. Edit the sdl-config script so that it gives 
the correct SDL directory when invoked.

* Extract the current CVS version of QEMU.

* Start the MSYS shell (file 'msys.bat').

* Change to the QEMU directory and launch './configure' then 'make'. If 
you have problems using SDL, verify that 'sdl-config' can be launched 
from the MSYS command line.

Fabrice.

I guess cross-compiling for Windows from a linux host isn't supported?
These are the problems I stumble over when I try to do just that:
* The SDL probe in 'configure' uses the host's CC instead of the target
  CC, causing the probe to fail.
* After hacking around that, it appears that dyngen is compiled as a .exe
  instead of a host binary, causing Wine to launch whenever dyngen is used
  in the build process.
* -lutil is used for final linking, but libutil.a is a component of glibc,
  and I didn't dare trying to build it for Windows (does that even work? :)
  It doesn't even seem to be needed -- removing the '-lutil' causes a
  qemu.exe to be built anyway.

After qemu.exe is built, it doesn't seem to work.  It does run, but simply
refuses to output anything:

F:\>qemu.exe

I am working on doing a cross compile right now...

The first hurdle was dyngen.exe. It ran fine for me with wine, though (I
am using crossover office version of wine though... don't know if that
matters).

Alternatively I posted a patch to this list which will allow you to
generate an op.h which has the binary code in it as source code in op.h
so you can generate the op.h on Linux and use it in the mingw build.
Kludgy but works.

Now I'm working on building SDL. I'll post here with instructions once I
get everything working... I can't imagine this should be too hard...

(It doesn't matter, runs fine with regular wine.)

[-- Attachment #1: Type: text/plain, Size: 2921 bytes --]

I get the same behavior... qemu that is built just silently exits, with
no output.

The SDL probe can be fixed by moving it down just after cc is redefined
to include the cross compiler prefix.

I did the same thing you did and removed the -lutil prefix to get the
last step to compile.

There does seem to be one more issue in the install for the main
Makefile... it wants to copy a the qemu-mkcow utility but the TOOLS
macro is already set to nothing because CONFIG_WIN32 is defined.

Some details:

I am using the following to build SDL:

./configure --host=i586-mingw32msvc --disable-nasm
--prefix=/home/john/projects/SDL-1.2.7

I added /home/john/projects/SDL-1.2.7 to beginning of my path so that
sdl-config would be found there.

Then I configured QEMU to make the cross compiler prefix under the
--enable-mingw32 option to match my compiler. I ran

./configure --enable-mingw32 --prefix=/home/john/projects/qemu
make install

qemu.exe gets created in i386-softmmu

I copied qemu.exe and SDL.dll from the SDL build to my vmware Win2K, and
upon running it fails as described above.

I wonder if I am missing copying over some library to the windows box.

Well, I tried running the cross-compiled qemu.exe from an MSYS prompt
and it did run. Something special about the MSYS environment that makes
it work... different DLLS? Environment variables? Dunno. Anyway, it
won't load the bios.

$ ./qemu --cdrom ./MorphixCombined-LightGUI-0.4-1.iso
-L/home/Administrator/pc-bios
qemu: could not load PC bios

So at one point and who should post a story to Slashdot or another news
site about Kazu's port? I'd personally call this newsworthy. And it
could bring a spike of new interest to the project that could help get
the remaining drivers knocked out, and probably even more interest for
QEMU generally.

Before making an "official" announce, it is better to wait for the 0.5.3 
release as it contains big improvements compared to the 0.5.2 (I will 
release it before the end of the week).

come to this - is there a way to tighten the release schedule in order to have 
new versions come out more frequently?
this would allow distributors to build up-to-date packages of qemu, and we 
might even be in the news every month.
personally, i don't like building from cvs, since you can never know if it 
will even compile. the old gentoo-issue, you know. packages made by people 
with a better understanding of things than i (and many others) have, would 
compile, so we would have a lot more people testing qemu and providing 
feedback.
if you believe that a release is compileable but not quite release-worthy, you 
could for example name it 0.5.3pre1 or something like that.

i just believe that more releases mean more testers and more publicity.

I hardly belive that any distribution will include QEMU, since there are over 
dozens of patents covering this area and I don't see any Linux distributions 
running to pay those patents fees to IBM, Intel, VMWare, Connectix 
(Microsoft)..

gentoo does include qemu since january. maybe a different thing since they 
don't provide binaries or ship the software on cd. they just mirror the 
sources.
then, again, i'm not an expert when it comes to software patents. i just know 
they're useless.

Qemu is in Debian unstable, the only distro that counts ;-) . And Bochs,
plex86 as well. Can't speak for other distros, since I don't use them.
Anyway there are quite a few Debian based distros the most well known
(besides Debian itself) being Knoppix, Morphix... gasp, Lindows even.

Anyway, until the lawsuit comes, patents aren't really an issue. Believe
me IBM probably has a patent on every nook and cranny of an operating
system, but unless they decide to go out and sue someone it doesn't
matter. Most companies keep a patent portfolio to prevent other
companies from suing them (of course the government should change the
law to completely do away with software patents).

Also if you're an engineer the going wisdom is that you shouldn't go
looking for patents either, as willful infringement is a whole different
ballgame in the eyes of the law...

  I don't understand a thing to these patent issues (and I would be very
interested by an explanation as qemu is released under GPL like license), but 
I can assure you that qemu 0.5.2 is know in debian sarge. That's where I get

No, because making a release takes time and because QEMU is not mature 
enough. Of course, anyone is free to make daily CVS snapshots available 
on a web site.

IMHO, using Qemu, we can run a small compilation farm
and build our own packages.

At present, I am building a small farm for the pgAdmin III project 
(http://www.pgadmin.org) precisely to compile RPMs and other packages.

Yeah, but if doing releases take cycles out of Fabrice, I would certainly
prefer him working on QEMU rather than doing releases :-)

And, frankly, as long as QEMU does not boot Win2K and WinXP reliably, there
is no need to do too much publicity (to not have a horde of newbies coming
here complaining about Windows not booting properly).

ReactOS works sweet though. I think qemu might make quite a chance to be
the successor to bochs in release packages of ReactOS.

Unfortunately it freezes after about 5 minutes.  qemu 0.5.2

I would send the latest cleaned up version of my FreeBSD patch if I
hadn't problems with CVS. It seems that the savannah server is down.
Is anyone else experiencing this?

I tought including FreeBSD port (actually it should work on NetBSD
and OpenBSD, too) in the next release would be great. I will keep trying
to get CVS working.

This is a patch for current CVS.

A patch of dyngen.c is only for cc_table. It is in op.c, so a location of
cc_table[CC_OP].compute_c() in op_update_inc_cc function has a offset value
from a head of .data section not a head of cc_table. So it needs to modify
addend.

In vl.c, O_BINARY needs to read binary file.

timeKillEvent ends timer.

To test the program, apply this patch, make and type at i386-softmmu
directory if linux.img is at the top of qemu source code:

i386-softmmu$ ./qemu.exe -L ../pc-bios --hda ../linux.img

Double hyphen needs to set hard disk image.

If there is not texi2html at make, type at the top of source code:

qemu$ touch qemu-doc.html

There is a problem. Keybord layout is wrong in Japanese. I can not type in
Linux.

Have fun,
kazu
