I am using PE from CW 10.6 with the GCC.
The target is a Kinetis KE02, handling some basic I/O and serial communication.
The PE components used in my project are ADC, IntFLASH, BitIO, TimerInt, AsynchroSerial, WatchDog and PWM.
When looking at the .map file, I have noticed, that the linker includes some quite big library functions from "libc.a" like "pformatter", "strtoul" and "sformatter", which I can't relate to any functionality of my code, nor the included PE components (no calls to "printf" or "scanf" in my code).
I have tried to disable the usage of the "default libraries" in the general Linker settings, which gives me the following error from the linker:
C:/MyProject/Project_Settings/Linker_Files/ProcessorExpert.ld:219: undefined symbol `__pformatter_' referenced in expression
mingw32-make: *** [MyProject.elf] Error 1
Line 219 is the last (and empty) line of the linker command file, which PE generates automatically, but I can't find any usage of the library functions in that file.
Does anyone know, why these library functions are included and if there is a way to avoid their inclusion in the project?
