When using WireGuard with Arduino R4 UNO Wifi, "fatal error: freertos/FreeRTOS.h: No such file or directory" occurs

Projects Programming
1

I want to send data from an Arduino R4 UNO Wifi to a cloud server, so I am creating a program that uses WireGuard, the cloud server's communication standard.
I get a compilation error in WireGuard.cpp with the message that freertos/FreeRTOS.h cannot be referenced.
I have been researching the cause and solution for several days, but I still don't know, so I would appreciate some advice.

IDE2.3.6 and the project code is uptime_post.ino.
The board manager used is Arduino ESP32.
The libraries used are WiFi, WireGuard-ESP32, and R4HttpClient.
Communication from the Arduino R4 UNO Wifi uses Wifi.

-------------- error message --------------

Your topic does not really indicate a problem with IDE 2.x and therefore has been moved to a more suitable location on the forum.

Thank you for pointing that out.
I apologize for my inexperience, I have rewritten it in English.

The Renesas CPU in the R4 is not running FreeRTOS.

You can try to modify the firmware of the ESP32 to handle Wireguard.

Thank you for your comment.
The board manager is Arduino ESP32 Boards (Ver.: 2.0.13).
After downloading uno-r4-wifi-usb-bridge-main.zip, the "Include library" in the library manager (menu->sketch->Include the library) resulted in "Error: 13 INTERNAL: Library install failed: moving extracted archive to destination dir: library not valid."
Is this approach a problem ?

I have not worked with the firmware yet...

But my guess is that you need Linux (WSL should do) and arduino-cli.

To compile it you need to follows the steps in the Readme.md.

Thank you for your advice. I was developing only with Windows 10 IDE2.3.6. I will consider implementing README.md including creating a Linux (WSL) and arduino-cli environment.
