Dear, Using Guix 58af4c9, the package ’sbcl’ seems not-reproducible.
The output of “guix challenge” is: --8<---------------cut here---------------start------------->8--- differing files: /lib/sbcl/contrib/sb-rt.fasl /lib/sbcl/contrib/uiop.fasl /lib/sbcl/contrib/sb-cover.fasl /lib/sbcl/contrib/sb-capstone.fasl /lib/sbcl/contrib/sb-executable.fasl /lib/sbcl/contrib/sb-bsd-sockets.fasl /lib/sbcl/contrib/sb-simple-streams.fasl /lib/sbcl/contrib/sb-queue.fasl /lib/sbcl/contrib/sb-gmp.fasl /lib/sbcl/contrib/sb-aclrepl.fasl /lib/sbcl/contrib/sb-sprof.fasl /lib/sbcl/contrib/sb-grovel.fasl /lib/sbcl/contrib/sb-posix.fasl /lib/sbcl/contrib/asdf.fasl /lib/sbcl/contrib/sb-mpfr.fasl /lib/sbcl/contrib/sb-cltl2.fasl /lib/sbcl/contrib/sb-concurrency.fasl /lib/sbcl/contrib/sb-md5.fasl /lib/sbcl/contrib/sb-introspect.fasl /lib/sbcl/contrib/sb-rotate-byte.fasl /lib/sbcl/sbcl.core /bin/sbcl /share/sbcl/src/runtime/coreparse.o /share/sbcl/src/runtime/sbcl 1 store items were analyzed: - 0 (0.0%) were identical - 1 (100.0%) differed - 0 (0.0%) were inconclusive --8<---------------cut here---------------end--------------->8--- which is confirmed by the experimental Data Service webpage: https://data.guix-patches.cbaines.net/revision/4e0498c4d3f5ef03ac5afa4a3e570205c10c28c5/package-derivation-outputs?search_query=sbcl&output_consistency=not-matching&system=x86_64-linux&target=none&after_path=&limit_results=&all_results=on I do not know if the patches in ’staging’ will fix this. Note that this issue does not imply that the build system ’asdf-build-system/sbcl’ is or will be not reproducible. However, this issues cuts any Diverse Double Compiling attempt. All the best, simon
