Error on Linkit ONE

[idreamsi]

Hi I using Lora Shield and LinkIt ONE, When I compile with the following error :

Arduino: 1.6.8 (Windows 7), Board: "LinkIt ONE"

Warning: platform.txt from core 'MediaTek ARM7 EJ-S (32-bits) Boards' contains deprecated recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} "{build.path}/{archive_file}" "{object_file}", automatically converted to recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} "{archive_file_path}" "{object_file}". Consider upgrading this core.

Error compiling for board LinkIt ONE.

What's the solution ? Note : I found this PR to be relevant (But it did not work.): https://github.com/matthijskooijman/arduino-lmic/pull/27

It looks like the arduino corefor this Linkit board does not implement the entire API that the normal Arduino core does. The "SPISettings" class was added somewhere one or two years ago, so perhaps the Linkit folks haven't picked that up yet? Perhaps you're using an older version of it?
