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. > Seems some files or functions are missing?
