Hi ,
My env:
A MangOH green board and wp7603 module.
Legato version :17.08.1
Yocto version : SWI9X07Y_02.09.02.00
In Makefile I can define CFLAGS += -D_OPTION1 to let all c code include this defintion
(I have reference 16.10.1 build with say gcc -D what's the recommended method CFLAGS)
problem is solved…
