Serial not found for Arduino Zero

I have just reccently bought an Arduino Zero to play with debugging. Alas, I’m simply stuck with the simple HelloWorld. My .ini looks like

platform = atmelsam
framework = arduino
board = zero

But compiling croaks with

src/main.c:4:2: error: ‘Serial’ undeclared (first use in this function); did you mean ‘Sercom’?

The main.cpp is simply

#include <Arduino.h>
void setup() {

void loop() {}

Arduino is a C++ framework, why is this file called src/main.c? Rename it to src/main.cpp, and you shall be able to use C++ objects like Serial with no problems.

As you can see in the source, the C++ objects only get exposed to you in C++ mode (__cplusplus defined).

Well, what should I say? It’s not the first time that happened to me :frowning: I blame the compiler structure for that, but that’s another story I don’t want to roll out here. Anyway, thanks a bunch :slight_smile:
