Bug Summary
After upgrading ESP8266/Arduino core to v3.1.1, the Arduino extension regenerated th c_cpp_properties.json file with a compilerPath attribute having value causing following C/C++ configuration error:
Unable to resolve configuration with compilerPath: "@D:\Portable\Arduino\portable\packages\esp8266\hardware\esp8266\3.1.1\tools\warnings\default-g++"
On top of this line from C/C++ Configuration Warning output, the Code UI shows 5 instances of cpptools output windows, all having same content (see also snapshot below):
[Error - 18:20:27] Connection to server got closed. Server will not be restarted.
Then, the intellisense stops working at all, no cross reference can be followed (Ctrl+left mouse click) to see details of function or variable declaration etc.
Steps to reproduce
Just run VS Code, open any sketch with Arduino code (*.ino), even empty one. Popup error start to come up in the lower right corner - see snapshot:
Code snippet
Every, does not matter, even this simple blinking LED example:
byte go = LOW;
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, go);
}
void loop() {
delay(500);
go = 1 - go;
digitalWrite(LED_BUILTIN, go);
}Configuration
