On the systems - Alpine Linux - macOS - FreeBSD - NetBSD - OpenBSD - Cygwin the "make check" part of the build fails, trying to generate the file contrib/mom/examples/tests-mom.sh . For example:
$ make check ... make check-TESTS make[2]: Entering directory '/home/bruno/groff-1.23.0.rc4/build-64' make[3]: Entering directory '/home/bruno/groff-1.23.0.rc4/build-64' FAIL: contrib/gdiffmk/tests/runtests.sh GEN contrib/hdtbl/examples/test-hdtbl.sh SKIP: contrib/hdtbl/examples/test-hdtbl.sh PASS: contrib/mm/tests/LT_SP_AU_without_AT_works.sh PASS: contrib/mm/tests/LT_SP_multi-word_LO_SJ_works.sh PASS: contrib/mm/tests/MT-1-reports-all-TM-numbers.sh PASS: contrib/mm/tests/MT_5_includes_AT_in_SG.sh PASS: contrib/mm/tests/P-indentation-works.sh PASS: contrib/mm/tests/ms_cover_sheet_robust_to_missing_AF.sh PASS: contrib/mm/tests/mse_has-sufficient-footnote-space.sh PASS: contrib/mm/tests/place-equation-labels-correctly-in-displays.sh PASS: contrib/mm/tests/remove-stale-bib-entry-data.sh PASS: contrib/mm/tests/short-pages-do-not-overflow-stack.sh GEN contrib/mom/examples/tests-mom.sh /bin/sh: can't create contrib/mom/examples/tests-mom.sh: nonexistent directory make[3]: *** [Makefile:14129: contrib/mom/examples/tests-mom.sh] Error 1 The directory contrib/mom/ exists. The directory contrib/mom/examples/ does not exist. What's missing is therefore obviously a command $(MKDIR_P) contrib/mon/examples in the contrib/mom/examples/tests-mom.sh rule. In file contrib/mom/mom.am, between lines 116 and 117. Bruno
