The following phase works around the issue for me (for antioxidant) --
this makes "guix build --check" pass (at least for antioxidant):
+ ;; TODO: SOURCE_DATE_EPOCH support would be nice. Also maybe
better fit for a snippet?
+ ;;
+ ;; Make the rust-vergen reproducible and avoid causing
irreproducibility
+ ;; in dependents.
+ ("rust-vergen"
+ ,#~((add-after 'unpack 'remove-timestamp-irreproducibility
+ (lambda _
+ (substitute* (find-files "." "\\.rs$")
+ (("^extern crate chrono;") "extern crate chrono; use
chrono::Utc; use chrono::TimeZone;")
+ (("^use chrono::Utc;") "use chrono::Utc; use
chrono::TimeZone;")
Should also work for cargo-build-system, but untested.
Greetings,
Maxime
