rpi pico warning pri kompilacii

[Lukac Michal]

Zdravim, chcel by som si nieco vyskusat s rpi pico.
Nainstaloval som SDK podla navodu ale pri kompilacii prikladov mi to pise tieto chyby. (aj jednoduche blikanie ledkou.)

c:/progra~2/armgnu~1/12dbab~1.2re/bin/../lib/gcc/arm-none-eabi/12.2.1/../../../../arm-none-eabi/bin/ld.exe: c:/progra~2/armgnu~1/12dbab~1.2re/bin/../lib/gcc/arm-none-eabi/12.2.1/thumb/v6-m/nofp\libg.a(libc_a-closer.o): in function `_close_r':
closer.c:(.text._close_r+0xc): warning: _close is not implemented and will always fail

Ten poisledny warning som nasiel ze staci potlacit hlasenia toho typu.

ale neviem co s tymi funkciami. Je to OK alebo to treba nejak osetrit?
Ak som to spravne pchopil mal by som si ich napisat sam ale neviem vobec ako a co presne maju robit.
Teraz mam nainstalovanu verziu arm-gnu-toolchain-12.2.rel1-mingw-w64-i686-arm-none-eabi.
Na druhom PC este asi z pred roka ver. 11.2 a tam mi to nerobi.

dik,
Michal.
