Unable to compile in Arduino IDE 2.0.0 with arduino-esp32 core v2.0.5 (latest) #278

Open nonsintetic opened 2 years ago

nonsintetic commented 2 years ago

Code version: 4.0 Board: AI Thinker ESP32-CAM Partition Scheme: Minimal SPIFFS

Getting these errors when trying to compile. Guess it's something in the latest arduino core that's changed.
