qemu discuss - Sep 2006 - about build on sparc.

I''m building qemu-0.8.2-slaris on sparc(snv_47 on SunFireV440).
But, I haven''t succeeded to compile it yet, because of the
preferred-stack-boundary
gcc''s option.

I guess that option shouldn''t be used sparc (only x86-64).
If somebody have some suggestions, please let me know.

This isn''t supported yet. Martin is working on it, as part of his 
planned upcoming release of sparc binaries (sparcv8, sparcv8plus, 
sparcv9 I believe should all be supported then for all targets). Quite a 
bit of patching is required to get it all to work.

You don''t say what version of gcc you''re using, but gcc-4 is a
big no-no
right now with qemu.  Back off to gcc-3.x (the original port of qemu
to Solaris sparc that ended up in the cvs was done with 3.4.3 
from blastwave)
