I tried downloading the robot car software to my ESP32 cam board. I have the correct port number and the AI Thinker board selected. The program stops compiling with a "Error compiling for board AI Thinker ESP32-CAM" message. Can anyone shed some light on why this is occurring?

Thanks for any help that you can provide.

Dan

Maybe if you post your code somebody might be able to figure out what the problem is

@mr-owl 

I don't use Windows and I don't use ESP32, but your messages suggest that the compiler has a choice of two different libraries and may be selecting the wrong one(s).

For example ...  "Alternatives for WiFi.h: [WiFi@1.2.7 WiFi@2.0.0]"

Is this possible ?

Anything seems possible when you don't know what you're talking about.

It is using version  WiFi 2.0 . it appears to be using the version that  comes with the ESP32 ( board manager) in  Tools  If so that is the version I would think it should  pick    

I also notice "an error while detecting libraries  in sketch/ app_httpd.cpp " when complying . This is a canned program from Bill's code - why the error ?

I noticed he used arduino version 1.8.13  I used 1.8.15  could that be an issue  ?
