I'm doing a long-awaited upgrade from 2.7 RT-Preempt to 2.8.2 Debian.
I have an X200 VFD. It is only superficially different than the WJ200_VFD included. Like 2 coil numbers change. I modified it and compiled and included it in my Linux 2.7 installation- I stumbled all there there, but eventually got it compiled and going. But the steps I followed under 2.7 don't work. "./configure" isn't any task it can find.
I brought in my existing X200_VFD code into hal/user_comps. It includes modbus.h. It (and WJ200_VFD) fail compile for "modbus_t" being undefined (should be in header file). I found modbus.h that I think came with 2.8.2, but it's an empty file. I think the compile path is ok to find modbus.h, but why is the file empty?
I did look at github- there is supposed to be a modbus.h with contents there, but it's a modbus.h that contains "modbus_param_t". The WJ200_VFD file uses a different modbus.h that defines "modbus_t" (and all the other content is different). I found nothing in the installation of LinuxCNC on the drive, but I did fine https://github.com/stephane/libmodbus IS the correct one.
How do I include this so it compiles? What's actually broken here- why does the WJ200_VFD included with LinuxCNC not have the modbus.h file it needs to compile?
Full disclosure- I'm not a Linux guy. So, really basic simplistic difficulties might be the problem.
