Fixes <https://issues.guix.gnu.org/50676>.
Reported by Mathieu Othacehe <othacehe@gnu.org>.
Commit a779363b6a was partially incorrect:
references passed to #:allowed-references or #:references-graphs *can*
be lowered as references to grafted elements. This is for example the
case when doing:
(computed-file "partition.img" exp
#:options `(#:references-graphs ,inputs))
Here INPUTS must be lowered as a reference to suitably grafted elements.
Failing to do that, the reference graph will not match the actual
INPUTS.
However, when building a package, those references must indeed refer
only to ungrafted packages. This commit preserves that by having build
systems pass #:graft? #f.
* guix/gexp.scm (lower-reference-graphs, lower-references): Remove uses
of 'without-grafting'. This reverts
a779363b6a.
* guix/build-system/cmake.scm (cmake-build, cmake-cross-build):
Pass #:graft? #f.
* guix/build-system/glib-or-gtk.scm (glib-or-gtk-build)
(glib-or-gtk-cross-build): Likewise.
* guix/build-system/gnu.scm (gnu-build, gnu-cross-build): Likewise.
* guix/build-system/meson.scm (meson-build, meson-cross-build): Likewise.
* guix/build-system/trivial.scm (trivial-build, trivial-cross-build):
Likewise.
* tests/gexp.scm ("lower-object, computed-file + grafts"): New test.
* tests/packages.scm ("trivial with #:allowed-references + grafts"): New
test.
