You're the only one I know of who's looking into this.
I see that you're using libmodbus 3.1.2, all we build and test on is various
3.0 versions.
It looks like an API function changed between 3.0 and 3.1, so you have the
options:
1. Build without modbus support.
2. Figure out how to use the new libmodbus interface.
3. Downgrade your build system to libmodbus 3.0.
If you decide to add support for libmodbus 3.1, please send a PR against the
master branch.
