Linter (for libraries) is looking for dependencies on core snap lib of the host architecture instead of the target specified in --build-for. This is evident from the trace below, where when checking dependencies of an aarch64 shared object (MAC-IS.so) the LD_LIBRARY_PATH variable looks into /snap/core22/current/lib/x86_64-linux-gnu (and fails). 2022-11-10 15:18:51.725 executing: LD_TRACE_LOADED_OBJECTS=1 LD_LIBRARY_PATH=/root/prime/lib:/root/prime/usr/lib:/snap/core22/current/lib:/snap/core22/current/usr/lib:/snap/core22/current/lib/x86_64-linux-gnu:/snap/core22/current/usr/lib/x86_64-linux-gnu usr/lib/aarch64-linux-gnu/gconv/MAC-IS.so 2022-11-10 15:18:51.734 Unable to determine library dependencies for 'usr/lib/aarch64-linux-gnu/gconv/MAC-IS.so' The following trace has been generated with a part including coreutils:arm64 as stage-packages and building on an x86_64 machine with: snapcraft --build-for=arm64
