I forget the exact circumstances for how to reproduce this error, but basically if you either are missing a Makefile in a subdirectory and gets cd'ed to in Makefile.inc1, or via bsd.subdir.mk, you'll run into this problem, and it's not very intuitive: make: don't know how to make bsd.README. Stop Having a more intuitive error message, or checking for Makefile would be nice. Please note that this issue might be resolved via my proposed changes for conf/179111 . How-To-Repeat: - cd usr.bin - echo 'SUBDIR+= doesnotexist' >> Makefile - make obj
bdrewery made this behavior more intuitive on head recently.
