avr-gcc: suppress warning “'__progmem__' attribute ignored”

Question

does anybody know how this warning can be suppressed? there is no way for me to avoid them (they stem from a framework i use).

Thanks!

Answer 1

From the gcc(1) man page:

-Wno-attributes

Do not warn if an unexpected "__attribute__" is used, such as unrecognized attributes, function attributes applied to variables, etc. This will not stop errors for incorrect use of supported attributes.

Answer 2

just add static to your declaration

PROGMEM static char my_byte[100] = {0x00,0x01,0x02,0x03 ...... }

then retrieve it as

char any_byte;
int index;
any_byte = pgm_read_byte(&(my_byte[index])) ;
