[XIAO_ESP32C6] IRrecv.cpp:246:3: error: 'timerAlarmEnable' was not declared in this scope; did you mean 'timerAlarm'?

Version/revision of the library used

2.8.6

Describe the bug

When running the verify command on Arduino IDE, it refuses to compile. It seems to be related to recent modifications in the arduino framework as mentioned here: https://github.com/crankyoldgit/IRremoteESP8266/issues/2053

EDIT: The most promising solution seems to be in the PR: https://github.com/crankyoldgit/IRremoteESP8266/issues/2039

To Reproduce

• Open Arduino IDE
• Pick XIAO_ESP32C6 as the target board
• Click on Verify

Example code used

#include <IRremoteESP8266.h>
#include <IRrecv.h>
#include <IRutils.h>

// Define the IR receiver pin
const uint16_t kRecvPin = 10;

// IR Receiver setup
IRrecv irrecv(kRecvPin);
decode_results results;

void setup() {
  Serial.begin(115200);

  Serial.print("Starting IR receiver... ");
   // Initialize IR Receiver
  irrecv.enableIRIn();
  Serial.print("OK");
}

void loop() {
  // Check if an IR signal is received
  if (irrecv.decode(&results)) {
    Serial.println(resultToHumanReadableBasic(&results));
    irrecv.resume(); // Receive the next value
  }
}

Expected behaviour

I would expect the verify step to successfully compile.

I have followed the steps in the Troubleshooting Guide & read the FAQ

Yes

Has this library/code previously worked as expected for you?

No

Other useful information

I am a bit rusty in C, it dates back to my Electrical Engineering Classes in 2015. I am trying to build a volume controller for my Devialet speaker to control it with an AppleTV remote, copying the behaviour of a working PoC in NodeJS.

[cadesalaberry]

I went ahead an tried another branch of the library from this PR: https://github.com/crankyoldgit/IRremoteESP8266/pull/2040 Doing the following (On a Mac M2) seems to have solved my problem:

cd ~/Documents/Arduino/libraries/
rm -rf IRremoteESP8266/
git clone git@github.com:tonhuisman/IRremoteESP8266.git
cd IRremoteESP8266/
git switch feature/C++20-compatibility

Then I restarted my IDE, pressed "Verify" which led to a successful build 🎉

@tonhuisman do you know what is missing to merge your PR?
