I changed the last command to --8<---------------cut here---------------start------------->8--- (find (lambda (pkg) (and (package? pkg) (not (member "aarch64-linux" (package-supported-systems pkg))))) (map cadr deps)) --8<---------------cut here---------------end--------------->8--- because some packages have local files among the development inputs. This search doesn't work for all cases though. For "python-jupyterlab" (from the guix-science channel) it returns no problematic dependencies, and yet I cannot build the package for aarch64-linux. The problem in that case seems to be cross-compilation. The dependency of python-jupyterlab that fails to build is libwebp, whose build log says: @ unsupported-platform /gnu/store/7fj9ckgxw27r196vkisc9cm3n8v9072x-libwebp-1.3.2.drv aarch64-linux while setting up the build environment: a `aarch64-linux' is required to build `/gnu/store/7fj9ckgxw27r196vkisc9cm3n8v9072x-libwebp-1.3.2.drv', but I am a `x86_64-linux' Maybe this would build on an actual ARM64 machine. Cheers, Konrad.
