Subject: bug#55846: make bootstrap -j2 fails on macOS
Date: Wed, 8 Jun 2022 12:41:54 +0200 [thread overview]
Message-ID: <7DB20A42-BE90-4679-81A2-1401B4ED73F5@acm.org> (raw)
nextstep/Makefile.in has the rule
${ns_check_file} ${ns_appdir}: ${srcdir}/${ns_appsrc} ${ns_appsrc}
rm -rf ${ns_appdir}
${MKDIR_P} ${ns_appdir}
( cd ${srcdir}/${ns_appsrc} ; tar cfh - . ) | \
( cd ${ns_appdir} ; umask 022; tar xf - )
[ "`cd ${srcdir} && /bin/pwd`" = "`/bin/pwd`" ] || \
( cd ${ns_appsrc} ; tar cfh - . ) | \
( cd ${ns_appdir} ; umask 022; tar xf - )
touch ${ns_appdir}
but because of its dual targets, ns_check_file and ns_appdir, it is unsafe to use in parallel builds and seems in fact often to be invoked twice at the same time, which leads to general confusion and eventual build failure.
