--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to lesto fante from comment #0) > My code stop compiling after updating from > arm-none-eabi-gcc (Arch Repository) 12.2.0 > to > arm-none-eabi-gcc (Arch Repository) 13.1.0 > (cant easily test any version in-between) Please add the output of 'gcc -v' (as requested by the bug reporting docs), the info above doesn't tell us much. Presumably you're using newlib to provide the libm functions that <cmath> declares?
