I have downloaded multiple versions of xtensa-esp32 elf, but none of them can find the c++config.h file

Sketch

#define LED1_BUILTIN 12
#define LED2_BUILTIN 13
int LED=1;
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED1_BUILTIN, OUTPUT);
  pinMode(LED2_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED1_BUILTIN, LED);   
  digitalWrite(LED2_BUILTIN, !LED); 
  delay(100);
  LED = !LED;
}

I installed esp32 by espressf Systems in the Board manager of Arduino IDE. I only tried versions 2.0.16 and 2.0.10, but I feel that the other versions are the same.

we usually get this when the username on Windows is too long (there is a path limit that get's overflowed with some toolchains). We have done our best for v3.0.0 to resolve this by shortening the RV toolchain package name, but very long username can still trigger it
