What version/git SHA of libvirt are you generating against?

I'm not experiencing your specific error, but a different error after upgrading my version of c-for-go.

c-for-go cef5ec7833f3274488b3edd519f46ddfb57d5735 is the last version of c-for-go that works for me:

$ LIBVIRT_SOURCE=/home/ckuehl/src/libvirt go generate ./...
  processing libvirt.yml done.
protocol file processing
  processing src/remote/remote_protocol.x
  processing src/remote/qemu_protocol.x
$ echo $?
0

Starting at c-for-go c95ebd03aba931e7248a6011f86d822ab878d00c, this is the error I get:

Hi connorkuehl,
Thank you so much for your reply! c-for-go cef5ec7833f3274488b3edd519f46ddfb57d5735 works for me and version/git SHA of libvirt on my environment is d427102fbd690cb2f43dbf33751cc5194a5b16ce.

My working environment is below:

I also meet this error and resolve this by building libvirt and install as following:

meson setup build
ninja -C build install

from go-libvirt.

I run code generators through docker and my steps are below. Hope this can be helpful for others.

sudo docker run -it ubuntu:20.04 bash
apt-get update
apt-get install git python3 python3-pip python3-setuptools python3-wheel ninja-build libxml2-utils xsltproc libglib2.0 libgnutls28-dev libxml2-dev wget -y
pip3 install meson docutils

cd /root
git clone https://github.com/libvirt/libvirt.git
cd /root/libvirt
meson setup build
ninja -C build install

wget https://go.dev/dl/go1.20.1.linux-amd64.tar.gz
rm -rf /usr/local/go && tar -C /usr/local -xzf go1.20.1.linux-amd64.tar.gz
