Hello, good afternoon! Let’s see if someone can tell me where the error is…
I have a project on Arduino which works perfectly, but when it comes to transferring it to platformio I get an error, I have installed some of the libraries through the wizard and others with a zip file, since they do not appear in the list of libraries. When compiling the code I get the following error:

I think it is a problem with the ESPAsyncWebServer library but I don’t know how to solve it. Thanks in advance! All the best!!
In a pure .cpp file, you need to declare the function prototype before you use it. This is in contrast to the .ino format in the Arduino. Double check that you are following the FAQ.
Hello, thank you for your answer, but I still have the same… I understand that you have to declare it before the Setup, but I don’t know how, the things I have always done have always been in Arduino and I wanted to manage platformio to have everything together (the website and program)…
The one that needs to be declared would be this, but I don’t know…
The procedure is always the same: You copy everything starting from the return value up before the function definition with the { begins, then add a semicolon.
I tried that before answering but I got more errors, then I read in a forum thread that putting all the functions before setup could work, but nothing remains the same, in fact the errors increase…

Wow… I’m in trouble with the libraries… that was because I didn’t look at the one I copied from the Arduino folder…
I think that now it compiles well, now I have to go for the flash memory that I want to use, 8MB instead of the 4MB that I had before… but that’s another story…
Thank you very much for helping and being patient! All the best!
