moves the complexity of Autotools variable expansion outside of the application code. * scripts/guix.in (config-lookup): Delete. (maybe-augment-load-paths!, run-guix-main): Use fully expanded variables instead of calling ‘config-lookup’. * configure.ac: Don't use AC_CONFIG_FILES for ‘scripts/guix’. Use AC_PROG_SED. * Makefile.am (scripts/guix): New rule. (do_subst): New variable. (CLEANFILES, EXTRA_DIST): Adapt. Co-authored-by: Ludovic Courtès <ludo@gnu.org> Mathieu Lirzin 2017-03-20build: Install .go files to $libdir/guile/X.Y....* configure.ac: Define and substitute 'guileobjectdir'. * Makefile.am (nobase_nodist_guilemodule_DATA): Remove $(GOBJECTS). (nobase_nodist_guileobject_DATA): New variable. (guix_install_go_files): Adjust accordingly. (install-data-hook): Likewise. * scripts/guix.in (config-lookup): Add 'exec_prefix' and 'guileobjectdir'. Add '_' in VAR-REF-REGEXP. (maybe-augment-load-paths!): Distinguish OBJECT-DIR from MODULE-DIR. Ludovic Courtès 2016-04-06challenge: Really exit with non-zero upon hash mismatch....Reported by John Darrington. * guix/scripts/challenge.scm (guix-challenge): Add an explicit 'exit' call when ISSUES is empty. * scripts/guix.in: Add comment about 'exit'. * doc/guix.texi (Invoking guix challenge): Mention the behavior and exit code.
