Error compiling for board Adafruit ESP32 Feather.

[hackerspace09]

I am trying to build an IR camera and am having trouble compiling for board Adafruit ESP32 Feather.

Arduino: 1.8.8 (Windows 7), Board: "Adafruit ESP32 Feather, 80MHz, 921600, Debug", esp32 1.0.0
Error compiling for board Adafruit ESP32 Feather.

Hello, I'm completely new to this but trying to make progress. I installed SiLabs CP2104 Driver. Then loaded ESP32 1.0.1 in board manager. I was unable to find Adafruit ESP32 Feather. I found post "Compile error on latest commit #866" with the same problem. I uninstalled ESP32 1.0.1 then loaded ESP32 1.0.0 in board manager. I restarted IDE and I was able to find Adafruit ESP32 Feather. :) However, I'm still having trouble compiling for board Adafruit ESP32 Feather. Any help is greatly appreciated.

### Debug Messages: None

How do I access the debug serial output?

So after 5 minutes scrolling down, I still didn't see the failing sketch.

You could also just paste in the error message itself: the linker doesn't find the void setup() and void loop() functions.

thank you I will try that next time, I didn't want to leave anything out.
Total noob error, didn't add a sketch. Got it now but a new error.

There are plenty of issues with failed connections. Install the latest driver for the USB chip of your board.

What could help: attach the board before starting Windows.

i am trying to build an IR camera and was using adafrut parts, but i got a TJC3224T024_001 and that is not the wright part. So I need help finding the librarys

This should work with all 3 revisions of the board.
