Adafruit "getEvent()" error

Projects Programming

I'm using the HMC5883 magnetic sensor. This sketch compiled, no problem, a year ago but now returns these two errors:

   virtual bool getEvent(sensors_event_t *) = 0;

It looks to me like this is in the Adafruit library code and I don't know how to resolve it. I'm using IDE 1.8.16. thanks.

You forgot to post it :joy:

Have you tried updating both libraries in the library manager?

Looks like a mismatch between the version of Adafruit_HMC5883_U-master and Adafruit_Unified_Sensor on which it depends. I'd go into Tools -> Manage Libraries... and see if there are updates available for either of those libraries.

Thanks. These libraries were downloaded a year ago (or more) and I believe they were the ones that worked at the time. I'll do an update and report back.

That did the trick. I had to go find all the stray libraries and delete these, then download and add the .zip libraries. I still get some C++ warnings, but the compile is OK.
