Description
Hello,
I did check the open and closed issues and the closest I have found is this: #4352
but it's not the same.
I am using Ubuntu 20.10, Arduino 1.8.13 and STM32 core 2.0.0.
In some of my sketches I test for the STM32 core version with this code
#if !defined(STM32_CORE_VERSION) || (STM32_CORE_VERSION < 0x02000000)
#error "Due to API change, this sketch is compatible with STM32_CORE_VERSION >= 0x02000000"
#endif
This compiles totally fine.
However, if in my sketch I explicitly add:
#include <Arduino.h>
this triggers the compilation error in the test.
It was my understanding that the Arduino build system automatically adds the #include <Arduino.h> to the top of the generated cpp code, so that would be a double inclusion and shouldn't change anything at all, but it seems it does.
Some help to solve this conundrum would be very much appreciated.
Note that the example sketches in the U8g2/u8x8 library all explicitly add #include <Arduino.h>, that's how I stumbled upon this problem.
