I haven't received an answer that fixed my problem, so here is another example.
I have a simple printf statement that causes a L103 error. No variables declared. Includes "stdio.h" and links in C51FPL.LIB. Others LIBs don't seem to link correctly either. Code compiles fine. Anyone know what the linking problem could be?
#include "stdio.h"
main() { printf("12345"); }
