[Qemu-devel] kqemu development - mingw issue

[Bartlomiej Celary]

Hi,
I have found a kqemu version 1.4 which should be working with current
development version of Qemu (got it from here:
http://www.sfr-fresh.com/unix/privat/kqemu-1.4.0pre1.tar.gz). I have
seen some posts regarding this peace of software and am not sure if it
is in any way developed. I am not sure if the author is still working
on it.

My actual problem is that under mingw I am not able to compile it. The
problem is in the ASM code (obviously...) which I have no idea about:

gcc -D__KERNEL__ -nostdinc -iwithprefix include -I. -I..
-D__ASSEMBLY__ -c -o i386/monitor_asm.o i386/monitor_asm.S
i386/monitor_asm.S: Assembler messages:

i386/monitor_asm.S:347: Error: unknown pseudo-op: `.previous'

I have only managed to figure out that the .previous directive is not
supported in my case, and so this peace of code is probably the
problem:

#define SEG_EXCEPTION(label) \
    .section "seg_ex_table", "a" ; \
    .long label ; \
    .previous

also another issue is tha " character...

Any help greatly appreciated.

Best Regards,
Bartek Celary

Are you using Windows to build KQEMU? AFAIK that won't work, because you
need ELF support + MinGW cross-compiler.

Why should you need ELF support?  The Windows support in kqemu should make 
a Windows service, which is COFF/PE as everything else in Windows...

Having said that, I was never bold enough to try to compile it myself.
