[pio][stm32f103c8] Cannot compile, ezTime.h:70:2: error: redeclaration of 'ERROR'

[thomas-maurice]

Hello !

I am trying to use the library on an stm32f103c8 (Bluepill) stm board using PlatformIO, it seems that the simple fact of including the library makes the compilation to fail because of a redefinition of the ERROR enum.

How to reproduce

platformio.ini:

[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
upload_protocol = stlink
build_flags = -D EZTIME_ETHERNET
lib_deps =
    Ethernet
    ezTime

src/main.cpp:

#include <Arduino.h>
#include <ezTime.h>
#include <Ethernet.h>

void setup() {
}

void loop() {
}

Do you have any idea how to fix that ? If you need more info feel free to ask !
