arduino\hardware\samd\1.6.14\cores\arduino/Arduino.h:48:17: fatal error: sam.h: No such file or directory

#include "sam.h"

^

why ???

IDE 1.8.4

Arduino MKR1000

example blink...

Hmmm IDE 1.8.4 ????
Would that be from the OTHER arduino site maybe ?
Maybe its a beta release in which case bugs are to be expected.

Any chance of additional details like OS, etc etc etc. Things mentioned in THIS THREAD that you passed on the way in.

I also have this issue.

I'm using IDE 1.6.7, on Windows 10

I get the following error message:-

C:\Users\blah\AppData\Local\Arduino15\packages\arduino\hardware\samd\1.6.15\cores\arduino/Arduino.h:48:17: fatal error: sam.h: No such file or directory

#include "sam.h"

I have seen others with the same issue are able to resolve it by removing the samd directory and then re-installing. I have tried this but not got any further.

I've tried both early and later versions of code - same issue

Google has shown that others have had this issue, but the solutions nearly always seem to be that of re-installing the board in Board Manager.

I can see the MKR1000 in the Com port list, so I know that at least that bit works.

Any ideas, anyone?

ah....it would appear that I'd not gone back in time far enough.
As the current version of SAMD is 1.6.15, I thought I'd go back 5-6 releases.

If I'd gone back to 1.6.7, I'd find one that worked.
Hopefully it will be resolved in 1.6.16, (but I'm not too sure what's happened to versions 1.6.8-15).
