I can't seem to reproduce this on Ubuntu 10.04

mdroth@illuin:~/w/qemu-0.15.0-rc0$ ./configure --prefix=/usr 
--audio-card-list=ac97,es1370,sb16,adlib,gus,cs4231a && make

   GEN   config-host.h
   GEN   trace.h
   GEN   qemu-options.def
   GEN   qapi-generated/qga-qapi-types.h
   GEN   qapi-generated/qga-qapi-visit.h
   GEN   qapi-generated/qga-qmp-marshal.c
   CC    qapi/qapi-visit-core.o

Error is defined in error.h, which is pulled into qapi-visit-core.c via 
qapi-visit-core.h via qapi-types-core.h

I don't see any indication that error.h wasn't found...so it must be 
getting pulled in and for whatever reason is not making the expected 
declarations...

If you could, can you please try reproducing this on qemu.git origin/master?

git clone git://git.qemu.org/qemu.git qemu.git
cd qemu.git
git checkout origin/master
./configure --prefix=/usr --enable-spice 
--audio-card-list=ac97,es1370,sb16,adlib,gus,cs4231a && make

The Error infrastructure was introduced a while back, so if it is 
something with that you should still see similar errors if you do:

git checkout c1990ebfa11265d3aa9b6a4d5d1a02bd3f9ac5c6
./configure --prefix=/usr --enable-spice 
--audio-card-list=ac97,es1370,sb16,adlib,gus,cs4231a && make

If you don't see an Error there, a bisect between those 2 changesets 
would be much appreciated.

Thanks!
