error: call of overloaded 'IPAddress(unsigned int)' is ambiguous

[perigalacticon]

I'd really like to try this library but I keep getting the error:

"error: call of overloaded 'IPAddress(unsigned int)' is ambiguous"

from the Demo.ino sketch. I updated all the libraries and esp32 core. It does the same thing.

Here is the function from the AsyncWebSocket.cpp library file:
IPAddress AsyncWebSocketClient::remoteIP() { if(!_client) { return IPAddress(0U); } return _client->remoteIP(); }

is "0U" a typo??

Here is the complete compilation output:

Could you please help me?

Update, if I comment out the offending lines of code in AsyncWebSocket.cpp it no longer stops there, but there are more errors. I am using AsyncTCP v3.4.10, ESPAsyncWebServer v3.9.4, esp32core v3.3.5.

[perigalacticon]

I tried these and I tried the latest libraries and I googled the errors which was USELESS and I STILL HAVE ERRORS UPON COMPILIATION

[mathieucarbou]

ESP32Async) AsyncTCP >= v3.4.9
(ESP32Async) ESPAsyncWebServer >= v3.8.1

>=

[perigalacticon]

THATS WHAT THE WIKI SAYS I TRIED THEM. IT DOESNT COMPILE.

[mathieucarbou]

It compiles fine and all examples compile. We have a CI in place.

The error comes from IDE usage / setup. You have to know how to properly use the IDE you are using. Here, you have a library mismatch or several times same libs in your Arduino lib folder. Just clean.

Also, please stop opening the same issue in different repos:

• error: call of overloaded 'IPAddress(unsigned int)' is ambiguous #368
• HighPerf.ino example from MycilaWebSerial library does not compile, gives errors: mathieucarbou/MycilaWebSerial#39
• HighPerf.ino does not compile mathieucarbou/MycilaWebSerial#38 (HighPerf.ino does not compile mathieucarbou/MycilaWebSerial#40)
• Can't compile demo code ayushsharma82/WebSerial#133

All these project work correctly and have some CI in place. You need to use your IDE correctly, or change it.

So please learn how to use your IDE and above anything else, please search if this issue is already known by someone else before you! There are 100% chance that someone got it before you.

little search...

Thank you.

NONE OF THESE LIBRARIES COMPILE. I don't want to "use a real IDE" I am an ARDUINO USER. I AM NOT A PROPFESSIONAL PROGRAMMER. DO YOU UNDERSTAND? OF COURSE YOU DONT BECAUSE YOU ARE A PROFESSIONAL PROGRAMMER WITH LOTS OF ISSUES. I POSTED THE SAME ISSUE IN DIFFERENT REPOS BECAUSE ALL OF THESE LIBRARIES GIVE THE SAME ERROR, AND I AM SICK OF TRYING LIBRARIES THAT DONT EVER WORK BECAISE THE PROGRAMMER DOESNT CARE AND DOESNT MAINTAIN THEM AND DOESNT FOLLOW ANY STANDARD DISCIPLINES AND CAUSE PROBLEMS FOR EVERYONE JUST TRY TRYING TO MAKE SOME STUPID DIY PROJECT WORK THAT DOESNT GIVE A F*** ABOUT HOW YOUR BS LIBRARY WORKS. THE PROBLEM IS WITH THE LIBRARIES THAT ARE NOT WORKING RIGHT. I HAVE THE NORMAL STANDARD INSTALLATION OF THE ARDUINO IDE v2 AND YOUR LIBRARIES DO NOT COMPILE.
