Does your sbuild tree have arm64 binfmt emulation enabled? It would work then. I have found the issue: the score-p infrastructure assumes that Linux does not cross-compile (as opposed to bluegene etc. environments which do cross-compile). And another small bit about libdir. It does cross-build on my box, it should be fine on salsa as well, we will see on https://salsa.debian.org/debian/otf2/-/pipelines/935033 Samuel
