I am sorry if this is in the wrong place or a silly question .
I have been using for a long time Freescale’s CodeWarrior IDE and all my projects I have a typedefs.h file to Typedef integer values into the name I am most familiar with. Here is a screen shot showing the errors that have never been reported in the CodeWarrior IDE
Do you have a #include <stdint.h> or #include <stdbool.h> somewhere, or include a file that does so (e.g., #include <Arduino.h>)? These will be conflicting with what you’re trying to define.
