The following works for me: $ sdcc -mpic16 -p18F25J50 -E -Wp,-dM t.c #define STACK_MODEL_SMALL 1 #define __pic16 1 #define __STDC_HOSTED__ 0 #define pic18f25j50 1 #define SDCC 312 #define SDCC_REVISION 7243 #define __18f25j50 1 #define SDCC_pic16 1 #define __STDC__ 1
So you should use #ifdef __18f25j50 or #ifdef pic18f25j50. Borut On 01. 02. 2012 17:55, Raphael Neider wrote: > Dear Tamas, > >> I need to know which compiler directives are set.
