ModbusIP ENC28J60 Compile errors

[dcuesp]

Hi everybody. I,m using Arduino IDE 2.0.4 software version (but i have tried with 1.8 with same results) and the ModbusIP ENC28J60 library, from Github. As soon as i complile any of the examples included in it, i get several errors. I have no idea what the problem is, i tried with different software version, to reinstall it, but nothing help. Has anybody faced this trouble? Could anybody give me a peace of advice?

Thanks in advance.

Compile errors:

error: 'class ModbusIP' has no member named 'addIreg'
error: 'class ModbusIP' has no member named 'Hreg'
error: 'class ModbusIP' has no member named 'addIsts'

Activate verbose output during compile in the preferences and post the complete output (no pictures!).

I guess you have installed several libraries that contain classes matching ModbusIP and the IDE took another one than you think.

Hi, here you have the complete output. I hope it will help. Thanks!

[pylon]

The library ModbusIP_ENC28J60 expects the Modbus library from the same Github repository as itself to be installed. You have some other library of that name installed (the IDE includes from this directory "C:\Users\danie\Documents\Arduino\libraries\Modbus\src" but the mentioned library in the repository doesn't have a src subdirectory). Install the correct library to make it compile.

[dcuesp]

After reading your answer, I've checked the librarys. Modbus is a contributed library installed from IDE library manager. ModbusIP_ENC28J60 was downloaded after from GitHub and installed as a ZIP library file. I have no idea of the structure of a library folder's should be, but following your advice i created a new folder called src inside ModbusIP_ENC28J60, and copied H and CPP files. It doesn't work. Moreover, then i also moved those files inside Modbus/src. Same result. Apart of that, having a look on Modbus.h, there are all the members of the class i can use in the project, but there is any member of the example's in ModbusIP_ENC28J60.h. In conclusion, and just in my eyes, this library isn't complete or something is missing.

@dcuesp

Modbus is a contributed library installed from IDE library manager.

Yes, but your ModbusIP_ENC28J60 library expects another library of the same name.

@dcuesp

I have no idea of the structure of a library folder's should be, but following your advice i created a new folder called src inside ModbusIP_ENC28J60, and copied H and CPP files.

Did I tell you to do so? I just told you that I realized you're using the wrong library because the one you're using has that subdirectory.

@dcuesp

In conclusion, and just in my eyes, this library isn't complete or something is missing.

Yes, exactly, that's what I told you.

As you failed to tell us where you got your library from, I referred to this Github location.

[dcuesp]

This library's link:

GitHub - andresarmento/modbus-arduino: A library that allows your Arduino to communicate via Modbus protocol, acting as a slave (master in development). Supports serial (RS-232, RS-485) and IP via Ethernet (Modbus IP)..

You were right. I didn't realize there was some librarys used that has the same name than the others available from Arduino IDE. After download all librarys from GitHub, the code is ruuning well.

Thank you very much for your help.
