Thanks - I hadn't noticed that. However I did a clean install of Zorin OS 17.1 Core (a Ubuntu 23.10 derivative) on a VirtualBox VM and then did the following: ``` # Install minimal dependencies to allow git, bootstrap and configure to work sudo apt install git libtool pkg-config make # Clone OpenOCD cd ~/Downloads git clone https://github.com/openocd-org/openocd # Bootstrap ./bootstrap ... # Configure ./configure --prefix=... ...

I expect that such a change would be trivial so I am happy to review it but I expect that acceptance would depend on somebody else.
