How did you configure it?

After applying a small build patch, this works for me:

  cp ~/qemu-dbi/trace-events ~/
  sed -i -e "s/disable tcg vmem(/instrument tcg vmem(/g" trace-events
  mkdir -p ~/qemu-dbi-build
  cd ~/qemu-dbi-build
  ~/qemu-src/configure --with-trace-events=../trace-events 
--with-trace-instrument=dynamic --prefix=/tmp/qemu-install 
--enable-trace-backend=stderr --target-list="i386-softmmu"
  make
  make install

I've update the repo with the aforementioned patch.

I might do it in the future, but for now my todo is full enough with other
tasks :)

Right, I should proofread the docs.



Thanks,
