I've just tried to add this functions in Makefile.am, in clib_routines, as this form
clib_routines := htonl htons ntohl ntohs \
udivdi3 __udivdi3 __udivmoddi4 __umoddi3 \
__divdi3 \
__rel_iplt_start __rel_iplt_end \
__ffsdi2 \
ffs intel_startCPU local_bh_count local_irq_count \
_START _start etext _edata end _end # actually ld magic, not li$
But now It shows this error (attached file)
Feels that It's necessary to define this functions but I don't know where these functions are located.
How can I define this?
