I have run into a problem making a change in one of my ESP32 servers that I built from your server course some time ago. I need your help in fixing this issue. This issue occurred as I was trying to compile the code to create a new .bin fie. Keep in mind that this code has been working fine for a couple of years. I had to make a change in the I/P address and when I went to create the new .bin file I got this error. I am not sure if it is telling me that I need to add some code or is there a file missing? I have never seen the term <cmath>

Hi.
Do you use cmath in any of the files you have for your project?
Which board are you selecting when compiling the code?

Sara

Sara, This is the first time I heard of cmath. I have to say that if I do use it, I sure do not know about it. The board I have selected is the “nodemcu-32s”. That board name is specified in all the .bin files that I created previously.

Hi again.
I believe that’s something broken with your Arduino IDE or ESP32 boards installation,
On your computer, go to this directory: C:/Users/merke/AppData/Local/Arduino15/packages/esp32/
Delete the esp32 folder under the packages folder.
Then, install the ESP32 boards again: https://randomnerdtutorials.com/installing-esp32-arduino-ide-2-0/

Sara, The problem turned out to be with one of the library files that is in the #include section of the sketch. I found one that would not update automatically and I had to go to the library and delete it and then install the latest version. One problem solved and I am working on another one. When I formulate an intelligent question, I will post it here. we can mark this one solved.
