I did and found one problem not mentioned in the README.
I think is an mknative problem?
GCC on aarch64 generates references to libbid functions which do not
get linked:
../aarch64--netbsd/bin/ld: /work/src/../obj/destdir.evbarm/lib/libgcc_s.so:
undefined reference to `__bid_addtd3'
../aarch64--netbsd/bin/ld: /work/src/../obj/destdir.evbarm/lib/libgcc_s.so:
undefined reference to `__mulbitint3'
../aarch64--netbsd/bin/ld: /work/src/../obj/destdir.evbarm/lib/libgcc_s.so:
undefined reference to `__bid_adddd3'
Example is from building GNU flex.
Digging a bit more the default of --enable-decimal-float was changed
from "no" to "yes" between GCC 12 and 13 and accepts
--enable-decimal-float={no,yes,bid,dpd}
mknative does not seem to know about libbid but we do set
-DENABLE_DECIMAL_BID_FORMAT for libgcc so I think we need to either
make some changes to mknative for libgcc or rerun mknative w/
--enable-decimal-float=no.
Kind regards,
