Hi, everyone.
I have error "exit status 1" when compiling my ESP32 project.
I try to compile OTA and PZEM004T V30 project, It's ok. But my project is not.
Can who help me. Thanks,
This is my project: GitHub - Ankhang1107/ESP32_PZEM004_BLYNK_OTA: this project to read DHT11, PZEM004 sensor and connect to Blynk to follow sensor's values and OTA.
This does not sound like an IDE problem. I've moved your topic to a more suitable location on the forum.
Please post your complete error message (please don't forget to use code tags).
I can't open your RAR file (not sure why) and it is quite big.
Thank you for reply. Because have many libirary, so I use winraz. I will post source code below. Please check and help me.

You seem to have a problem in BlynkEdgent.h where you define the class VPinWriteOnChange again.
I don't use ESPs and I have no experience with Blynk so can help you further.
Next time, please no screenshots of errors. In IDE 1.x a button is available to copy error messages, in IDE 2.x you can right click in the output window and use "copy all".
I checked it and the seem it is no problem.
Here is error I copied
