gbranden pushed a commit to branch master
in repository groff.
commit 7af3bbe4dcdaba6f1d050096fafcf7123ec2dc4b
Author: Bruno Haible <[email protected]>
AuthorDate: Tue Jan 20 11:50:07 2026 +0100
Fix build problem with BSD Make.
* contrib/sboxes/sboxes.am:
* doc/doc.am:
* font/devpdf/devpdf.am:
* tmac/tmac.am: Fix portability problem involving BSD Make. Define
`*_builddir` macros without interpolating `top_builddir`. groff does
not use recursive make; all file specifications are resolved relative
to the top of the build tree, so the interpolation is unnecessary, and
with BSD Make it causes spurious failures because that implementation
uses strings, not file identities, as the nodes of its dependency
graph. So if you ask for "foo" to be built but have only a rule for a
target named "./foo", BSD Make fails, whereas GNU Make does not.
[If the foregoing explanation is defective, blame me, not Bruno. --GBR]
