How will we know when the new version has been incorporated into
QemuInstall-2004xxxx.exe?

I ask the above just because I figure someone else may have beaten me to it :^)

Also, would you consider making QEMUMenu.bat work with "dd for Win32"
as well as it works with Zitu's program. dd for Win32 is available
here: http://uranus.it.swin.edu.au/~jn/linux/rawwrite/dd.htm

The advantage it has over mkqemuimage.exe is that it can make any size
images, at least so far as I can tell. The logic John Newbigin emailed
goes as follows:

- - -

"The requirement is to create a big empty file which can be presented as 
a harddisk.  Under linux I would do this like this:
dd if=/dev/zero of=myfile.img bs=1024k count=3000
This will give you 3000Meg.

The file will be 'initialised' with \000s.  It is possible to create a 
sparse file which is 'hollow' and will be allocated when you write to 
it.  That can cause problems with some programs though so it is best to 
avoid that unless you know it works.

Windows does not share the philosophy which makes that kind of command 
possible.

Under windows, sparse files are not supported so we can use the dd tool 
in a different way.  If you write anything to a large offset (say 3Gig) 
then all the space before that will be allocated.

Pick a file which you can read and is larger than 1024 bytes and try 
this command:
dd if=filethatalreadyexists of=newfile.img bs=1k seek=3071999 count=1
here seek is the offset into the newfile to start the writing.  The 
number I am using = 1024 * 3000 - 1 which will give you 3000Meg again."

[Qemu-devel] SDL compile error

[Shivkumar Shivaji]

Hi,
   I keep getting this error when compiling qemu-fast with Suse 9.2. What
am I doing wrong? SDL and SDL-devel appear to be loaded. Is there an
issue with the latest SDL? What version of SDL does qemu-fast work on?

Thanks, Shivkumar Shivaji

The above is where the actual errors are. This means that your SDL is based
on an older glibc (2.0 or something) but you have upgraded to a newer one
(2.3 or something). The undefined symbols are internal glibc symbols which the
dynamic loader knows how to resolve (via some hacks in the newer glibc) but
which the static linker can't. The real fix is to download SDL source and
recompile, that way the new SDL static library will not reference those symbols.

If you want a quick hack, compile the attached ctype_b.c file and link it into
qemu-fast. You will probably want to edit the Makefile to do this. (You can
also link it into libSDL.a I suppose. I haven't tried this so I do not
recommend it.)

I hope I didn't offend anyone and I definitely didn't mean to imply
that dd for Win32 was somehow better than mkqemuimage.exe. Honestly, I
don't know anything about mkqemuimage--someone on the Mepis forum
suggested using dd so I investigated how to do that on Windows. Is
there a good reason to use mkqemuimage instead of dd for Win32? I have
no idea how to adjust mkqemuimage so that it meets my needs, but if
someone else wants to take on that project I suspect I'm one of many
people who would be grateful.

Is there a particular reason to not use qemu-img.exe?
mkqemuimage is perhaps much simpler to use but have this 2G limit and only
output raw images.

Anyway this is a nice tool that have been created for making empty images
to use with qemu on windows instead of borrowing one from another project.

OOops, sorry, I wanted to say that qemu-img.exe should be used instead 
of other tools as it handles all images formats that QEMU supports and 
some manipulations like AES encryption and compression.

Perhaps I could remove mkqemuimage from the windows installer now, move it
in a subdir, or put some info about images in a Readme, so qemu-img is
used preferably. You choose.
I am not aware of frontends that use it, except for QEMUMenu.

About qemu-img.exe, it is not installed by default for windows build (?)

It's updated in today's build and in 0.6.1
(ftp://ftp.freeoszoo.org/qemu/win32/release/QemuInstall-0.6.1.exe)

I hope I have not breack anything because I have a new toolchain and I
have only do a duke3d test run :)

That isn't true. Under Windows, use the mksparse command.

Not all filesystems have to support sparse files but NTFS (and perhaps
ext2/ext3 one day under Windows?) does.
