I'm overlooking something stupid BME280 library

Once again, I've hit a roadblock and can't figure it out.

I'm trying to use a BME280 but for the life of me, I cannot find adafruit sensor.h

I can't get it to verify/compile and I've tried all manner of other vendors and EVERY time there is some sort of a conflict with the library. If I try to use the Sparkfun variant, I get a warning note that it's unusable as IDE says it's unusable due to syntax.

Any suggestions?

I'm embarrassed that I have to ask what I'm sure are simple issues as I've successfully been using the Arduino platform for almost a year but periodically run into silly issues

I've been using the Sparkfun library successfully for more than a year. I did have to change one line to get RH as a float instead of int.

Can you copy-paste the error message?

Try compiling with the detailed output turned on. That will show you exactly where it is getting each library from.

How do I turn on detailed output?

Error message follows:

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

From the Adafruit_BME280_Library readme file:

Use of this library also requires Adafruit_Sensor to be installed on your local system.

Thanx!

I'll give it a shot

Re-read the last 3 lines of the error message again.
