Hi,
In the https://git.savannah.gnu.org/git/parted.git repository,
in bootstrap.conf there are the lines
gnulib_tool_option_extras="--tests-base=gnulib-tests --with-tests --symlink\
--makefile-name=gnulib.mk
"
mkdir -p gnulib-tests
But since
1) the directory gnulib-tests/ does not have a Makefile.am,
2) the top-level Makefile.am does not include 'gnulib-tests' among the
SUBDIRS,
this generation of gnulib-tests is pointless. You could drop it:
gnulib_tool_option_extras="--symlink\
--makefile-name=gnulib.mk
"
