From (guix tests): (define-syntax-rule (dummy-package name* extra-fields ...) "Return a \"dummy\" package called NAME*, with all its compulsory fields initialized with default values, and with EXTRA-FIELDS set as specified." (package extra-fields ... (name name*) (version "0") (source #f) (build-system gnu-build-system) (synopsis #f) (description #f) (home-page #f) (license #f))) If you need to use trivial-build-system, then I think you can't use the 'dummy-package' macro as it's currently implemented.
