ESP32 with 433Mhz - virtualWire library problem

Using Arduino Programming Questions
#1

Hello together, I´m trying to let arduino compiler compiling a sketch for ESP32, which includes the “virtualWire” library, but I get this message, simply including “#include <VirtualWire.h>” command line at the beginning of the code. Can someone please help me with this? :o
(As Background, I´d like to use ESP32, since my current weather station outdoor module I used an arduino nano with UART communication to an ESP8266 module AND a TX module which sends data to an indoor display via 433Mhz communication. Now I´d like to use ESP32, which just integrates WiFI functionalities AND the 433Mhz communication module to send data to the indoor station)

Below is the error from the IDE, I hope there´s a solution, I don´t want to also convert the indoor station through e.g. bluetooth… thanks a lot for your help

From the looks of the register names it is saying aren’t defined, it looks like you are using a library that was written for the AVR ARduinos like the UNO or the Mega. That won’t work on an ESP, it’s a completely different type of processor. It needs different libraries.

Thanks for your reply. Do you know if I can use another equivalent library for the ESP? My objective is to control the 433Mhz sender module as I did with the standard AVR microcontroller: would be very nice if it exists an equivalent library.
