If I buildworld buildkernel for arm.armv6 with the likes of: CFLAGS+= =mcpu=cortex-a7 CXXFLAGS+= =mcpu=cortex-a7 CPPFLAGS+= =mcpu=cortex-a7 (say for targeting a bpim3 or rpi2) then what package installs for that context tends to report: Undefined symbol "__aeabi_uidiv" In other words __aeabi_uidiv is only implemented for armv6 buildworld, not if one explicitly targets armv7. (armv7 has instruction support but that does not make software built to support other processor variants that are without instruction support also work unless the routine is still provided.) Note: I normally build ports from source anyway so this is just an FYI in case the lack of __aeabi_uidiv was not deliberate. === Mark Millard markmi at dsl-only.net
