Error compiling with Adafruit Feather v2: `esp_intr.h: No such file or directory`

[midgarth]

When trying to use Examples on an Adafruit ESP32 Feather V2 with tag 0.3.1 getting following error:

/Arduino/libraries/CAN/src/ESP32SJA1000.cpp:6:10: fatal error: esp_intr.h: No such file or directory
    6 | #include "esp_intr.h"
      |          ^~~~~~~~~~~~
compilation terminated.
exit status 1

Attempted to update the ESP32SJA1000.cpp to use esp_intr_alloc.h. as mentioned this issue : https://github.com/sandeepmistry/arduino-CAN/issues/138

When doing so get the following errors:

/Arduino/libraries/CAN/src/ESP32SJA1000.cpp: In member function 'virtual int ESP32SJA1000Class::begin(long int)':

I apologize if this is a very basic error/question.

Go to boards manager and search for ESP32, then go back to an older version, 3.0.3 gave the same problems you've mentioned. Going back to for example 2.0.11 will solve this.
