In compiling with Arduino 1.6.4 and the Reprap Discount Full Graphic LCD controller I got an error:
“initializer-string for array of chars is too long [-fpermissive]”
You can fix it by shortening the machine name in configuration.h to 16 characters here:
#define CUSTOM_MENDEL_NAME “Mostly Printed CNC”
… or by shortening the “ready.” to “OK” in language_en.h :
#define WELCOME_MSG MACHINE_NAME " ready."
#define WELCOME_MSG MACHINE_NAME " OK"
Works great with the change and I got to keep the entire name. I think the maximum for WELCOME_MSG is about 22 characters for the Full Graphic LCD. Not sure what the max is for other controllers. This error shouldn’t show up if you do not use an LCD controller.
