I’m posting this on the 3Pi forum as that’s the platform that I’m using. Read some other posts about setting the option flags on the GCC, but I left even more confused - too many options, and I don’t really understand how most of them apply to my issue. Namely, I am trying to avoid bloated code.
I was looking at code space (bytes used) and saw that some really simple programs were quite large. Decided to test a simple program that just turned on the red LED. Only used the red_led(1) command; however the .lss file showed that the green_led, left_led , right_led as well as a couple cryptic Orangutan LED routines were in the final code.
Is there a simple way to compile source code to extract only the the routines that are actually called?
