janneke pushed a commit to branch wip-tarball
in repository guix.
commit 45268fc2a2b8d85454bb2971946f6ab90b394b50
Author: Janneke Nieuwenhuizen <[email protected]>
AuthorDate: Sat Apr 6 11:34:49 2024 +0200
maint: Avoid EPS generation to fail silently, ensure reproducibility.
Currently, Graphviz' dot does not insert a %%CreationDate. ImageMagick's
convert on PNG->EPS does insert a %%CreationDate but it respects
SOURCE_DATE_EPOCH.
* doc/local.mk (.png.eps): Split single shell command into separate recipe
lines, prefixed by $(AM_V_at).
(.dot.png): Likewise. Check that generated EPS file has no %%CreationDate.
