Could this be fallout from the recent libc6 update?

I believe libc6 2.14 works properly. You have upgraded from 2.13 up to 2.15.

Filed bug 933045 on the problem in comment #2.

I will hand-define AT_EMPTY_PATH in the qemu source - it actually already is, but only under one #ifdef which is not related to the use of that define. So I think that's a qemu bug. Will send the patch upstream.

This bug was fixed in the package qemu-kvm - 1.0+noroms-0ubuntu5

---------------
qemu-kvm (1.0+noroms-0ubuntu5) precise; urgency=low

  * define_AT_EMPTY_PATH.patch: Make sure AT_EMPTY_PATH is defined.
   (LP: #930181)
  * Be smarter about what bridge to attach a TAP device to (LP: #475327):
    - qemu-ifup-choosebridge.patch: Don't use the default nic as a
      bridge, if it isn't a bridge.
    - debian/qemu-ifdown: use same logic as qemu-ifup to determine
      the bridge
    - debian/qemu-kvm.default: add commented TAPBR option

Same issue affects the qemu-linaro build. I'll copy the patch over from qemu-kvm.

This bug was fixed in the package qemu-linaro - 1.0.50-2012.02-0ubuntu1

---------------
qemu-linaro (1.0.50-2012.02-0ubuntu1) precise; urgency=low

  * New upstream release.
  * Pass --enable-uname-release=2.6.32 for the user emulation builds, so that
    we have a sensible baseline kernel value regardless of what the
    underlying host kernel is. This makes eglibc happier when running under
    emulation on a very old kernel for instance (whose host syscall ABI has
    nothing to do with what emulated syscalls are supported), and probably
    also lets us steer clear for the moment of code that has problem with
    the new kernel upstream versioning convention. LP: #921078.
  * debian/patches/define_AT_EMPTY_PATH.patch: make sure AT_EMPTY_PATH
    is defined. Thanks to Serge Hallyn <email address hidden>.
    Closes LP: #930181.

I still get the error with qemu-kvm-1.0+noroms-0ubuntu9

I downloaded the source and patch like this

Then i configured and compiled like this

gobuki@tatooine:/src$ ./configure --enable-vnc --enable-vde
gobuki@tatooine:/src$ make

Somewhere in the middle it stops with this message

Ok, i just did it wrong. The message ...

> dpkg-source: Information: qemu-kvm_1.0+noroms-0ubuntu9.diff.gz wird angewandt

... made me think the patch must have been applied, but apparently the debian patches aren't
applied by apt-get source

So, the right way is to issue these commands to build it, instead of configuring and making it yourself.

cd qemu-kvm-1.0+noroms
DEB_BUILD_OPTIONS="--enable-vnc --enable-vde"
dpkg-buildpackage -rfakeroot -b -j4 -uc -us

@Paul,

please see comment #9. Make sure you do 'quilt push -a' after extracting the package source. In particular this will apply the patch define_AT_EMPTY_PATH.patch.
