Hi,
I followed all steps mentioned in the https://wiki.teltonika-networks.com/view/RUT_Software_Development_Kit_instructions guide. But unfortunately I have the same issue.
make[4] -C package/network/services/hostapd compile
make[4] -C package/network/utils/iw compile
make[4] -C package/kernel/mac80211 compile
make -r world: build failed. Please re-run make with V=s to see what's going on
