Trying to compile example code failed

[liudr]

• I'm using Arduino IDE 2.3.2 and 1.8.19 with the same list of errors.
• Library version is 2.8.6
• ESP32 espressif board version is 3.0.6. I chose ESP32 dev board to compile with.

I think it must be something simple that I didn't get right. Thanks for your time!

Duplicate of #2039 (and several other duplicates)

[liudr]

What's the point of closing my thread without even knowing if I got a solution yet?

The #2039 you pointed to had no official word of solution. Someone mentioned using 2.0.17 (I suppose that's espressif esp32 for arduino version, not ESP-IDF version). Is that what you suggest? Others did mention versions 3.0.0.

If a developer would put "Requires ESP32 Arduino board definition x.x.x" on github project landing page, right where "how to install" is located, that would be very helpful, which is the first place I would look.

[liudr]

Compiling library 2.8.6 with esp32 by espressif systems 2.0.17(install within Arduino IDE's board manager) in Arduino 2.3.2 succeeded and I was able to run the CommonACcontrol example code. Had a tasmota ir firmware and an IR decoder to watch the code sent and confirmed the example code worked. This is for anyone finding this in the future when searching for example failed to compile.

[NiKiZe]

It is the exact same issue, what is the point of having multiple identical issues open, regardless of if there is a solution or not? (Put differently, why should maintainers spend time answering the same thing multiple times?)

But please do PR #2144, also see #2040 which is linked from the duplicated issue.

[liudr]

It is the exact same issue,

That was unfortunately only your perspective. From a user's perspective, there was a compilation error right off the bat. I searched some keywords in git for similar posts but came up with nothing so I posted. If you would take one suggestion to post the currently supported esp32 board version, this problem will be less for you. Now that I've posted a solution on this thread, hopefully others will see this and not bother you. I've done open-source contributions and not open-source work as well. Time is an important issue around such work, so is attitude.

[NiKiZe]

Your compile log is the same as other issues, which is due to a newer version of Arduino core for esp32 used in Arduino IDE, the fix is to update the code to work, see https://github.com/search?q=repo%3Acrankyoldgit%2FIRremoteESP8266+timerAlarmEnable&type=issues for other duplicates, even if the wording is s bit different, the actuall issue is the same.

And as mention please try #2144 and see if that fixes it for you, this is discussed in #2040 and also mentioned in #2039
