[Qemu-devel] [PATCH] Fix compilation on MinGW Windows cross-compiler

[Richard W.M. Jones]

Inspired by some comments by Anthony Liguori yesterday, I got qemu to
compile using the Fedora MinGW cross-compiler[1].

There are some problems introduced by what I think is new code (the
migration code), so I just hacked those bits out.  Not a good fix, but
the patch is attached anyhow.

After installing the MinGW packages in Fedora[2], the command to
compile qemu is:

  PATH=/usr/i686-pc-mingw32/sys-root/mingw/bin:$PATH \
  PKG_CONFIG_PATH=/usr/i686-pc-mingw32/sys-root/mingw/lib/pkgconfig \
  ./configure \
    --cross-prefix=i686-pc-mingw32- \
    --host-cc=i686-pc-mingw32-gcc \
    --cpu=i386 \
    --disable-gcc-check \
    --audio-drv-list=
  make

This produces Windows binaries (eg. qemu-system-x86_64.exe) which work
to some extent under Wine.  In fact I was able to boot a 64 bit Fedora
9 guest up to the point where it runs initrd, at which point qemu
crashes somewhere.

I didn't test the binaries on real Windows.

Rich.
