Problem Description

I am currently using a Windows 10 machine to code my sketches. I used the SimpleEspNowConnection library from here to get more utility out of the feature. I was currently coding for a versatile code that can be applied to either ESP32 or ESP8266. But when i compiled the code for ESP8266, the sketch compiler returned an error in the screenshot below;

first i thought that my code was wrong, and assuming that my code was mistyped i tried to compile the example sketch that was included in the library. but it turns out that the example sketch got the same error. I was confused, as last night i was able to compile it for the ESP32 one, but somehow it won't compile for the ESP8266. the library excplicitly stated that it supports both ESP32 and ESP8266. then out of curiosity, i had a Windows 11 machine with an Intel cpu. i tried compiling the code in that machine, and suddenly it compiled without a problem, as seen in the screenshot below;

I thought maybe my main machine was acting up, so i already did a restart multiple times, and re ran the comile side by side with the ESP32 one. the ESP32 still ran without a hitch, and is able to be flashed normally, meanwhile the ESP8266 one gave me a compiler error as seen in the screenshot below;

This is the sketch example that is included within the library / documentation.

There was once a woman who was very, very cheerful, though she had little to make her so; for she was old, and poor, and lonely. She lived in a little bit of a cottage and earned a scant living by running errands for her neighbours, getting a bite here, a sup there, as reward for her services. So she made shift to get on, and always looked as spry and cheery as if she had not a want in the world.\n\
Now one summer evening, as she was trotting, full of smiles as ever, along the high road to her hovel, what should she see but a big black pot lying in the ditch!\n\
\"Goodness me!\" she cried, \"that would be just the very thing for me if I only had something to put in it! But I haven't! Now who could have left it in the ditch?\"\n\
And she looked about her expecting the owner would not be far off; but she could see nobody.\n\
\"Maybe there is a hole in it,\" she went on, \"and that's why it has been cast away. But it would do fine to put a flower in for my window; so I'll just take it home with me.\"\n\
And with that she lifted the lid and looked inside. \"Mercy me!\" she cried, fair amazed. \"If it isn't full of gold pieces. Here's luck!\"\n\
And so it was, brimful of great gold coins. Well, at first she simply stood stock-still, wondering if she was standing on her head or her heels. Then she began saying:\n\
\"Lawks! But I do feel rich. I feel awful rich!\"\n\

Please read error: and warning: lines, library code contains an error that will cause a crash at runtime when running Core 3.0.0+. deleteBuffer() must return a value

ESP32 has the same issue btw, it's just hidden due to warning not being fatal since the Core does not force it to become an error
espressif/arduino-esp32#5321
espressif/arduino-esp32#5867

Another issue is IDE warning settings were unintentionally disabling -Werror=return-type. Core 3.1.0 will have a fix for the different build results you are seeing. Just our misunderstanding of how GCC handles warning flags and -w
#8495

ryuenma · 2022-06-21T03:41:12Z

Is there an estimate on when 3.1.0 will be released? or is there a temporary workaround that i can use to bypass the warnings/make it not crash? as for now i am unable to change the library as it would take a decent amount of time to understand another library.

Thank you for your answer and explanation

mcspr · 2022-06-21T07:08:43Z

I should empathize that disabling warnings is not a workaround! Missing return value may cause a crash, or may not. It is simply undefined behaviour, anything could happen.

Fixing the library would be best.
I have noticed that you already opened an issue at saghonfly/SimpleEspNowConnection#14
Brief search shows we could probably just change the return type from bool to void in both .cpp and .h, nothing in the library code checks what deleteBuffer returns

i got this after changing from bool to void, seems like it wasn't able to compile at all. there are other errors that popped up aside from this one also

sorry for the late reply

mcspr · 2022-09-22T17:42:23Z

Make sure of two things

that you have modified the correct deleteBuffer method. notice that there are two of those - one with bool, correctly returning bool and has return true; / return false;; and another one, where it also has bool but it does not return anything and should be void
.h and .cpp should have matching function signatures. like this

// .h
void deleteBuffer(const uint8_t *device, long id);

// .cpp
void SimpleEspNowConnection::DeviceMessageBuffer::deleteBuffer(const uint8_t *device, long id) {

ryuenma · 2022-09-22T18:02:00Z

Thank you, i have fixed the problem and modified the library for now.
