Compiling with esp8266

[eevora]

I´ve been using this library with arduino mega, it works very good, but now I want to use it with esp 8266 and the arduino IDE gives me an error ¨error compiling for esp 8266¨, this is because this library does not work with esp8266??

I don't really know, never tried that! For sure it has some dependencies on arduino internals, so it probably should be adapted for esp8266.
Anyway, what's the complete output error log?

The Error Log is this:

Maybe its something with the serial port of ESP8266 that its not compatible with the serial of the arduino mega, sorry the log its in spanish I´m from Cuba
This is the best library I've found for modbus polling, because it haves compatibility with float values among others things that I need for my project, If you could fix this issue it would be great, I know its a problem with esp 8266 because in my arduino mega 2560 the software run perfectly but when I change the compiler to ESP 8266 it gives this problem. I'm waiting for your answers, Thank you!!

Using the library on esp8266 without any problems. (vscode with platformio, but should be same with arduino ide)
Check your setup(s) and perhaps test with a blink sketch or similar to check that normal compilation is working.
