Another noob question: OneWire 2.3.5 won't compile

I'm rather new to Arduino, it's the first time I use a Bluno M0, now I'm trying to read a DS18B20 temperature sensor, so I need OneWire, but I'm stuck with an error message:

Code is simple 8-)
Code: Select all
#include <OneWire.h>   //Ver 2.3.5  installed
void setup() {
}
void loop() {
}

When compiling I get this:
Code: Select all
Arduino: 1.8.11 (Windows Store 1.8.28.0) (Windows 10), Board: "Bluno M0 MainBoard"

Error compiling for board Bluno M0 MainBoard.
Compilation is ok if I just select a different board.
I guess it must be simple to solve, if I just knew what to do
Thank-you for any help !
