Error Modbus RTU Slave ESP=IDF

[carlos789]

Hello:
I'm unable to get the Modbus example ( mb_serial_slave) to compile for ESP-IDF.
The following error message is generated:

I can't access menuconfig either. A file with the error description is attached.
I'd really appreciate any feedback on this issue.
