Apologies if this has been answered elsewhere - I did try search but couldn't find anything.

I am on the latest Arduino IDE and esp8266 board package but when I try to compile a sketch with the one wire library, I get the message above and text saying that the compiler is using the standard one wire library, not the one for the esp.

The full compile error text is below, I'm sure I have done something stupid but can't figure out what it is. Any help gratefully appreciated - thanks

- Sun Jul 26, 2015 10:26 am #24308 I've partially solved it myself by renaming the standard onewire to onewirestandard.

The compile picks up both but says it is now using the correct one and the compile is successful.

Obviously now if I need to compile for an arduino I'll have to rename it.

I'm sure there must be some setting somewhere to make the compiler look in the right place depending on the target.
