That way, ./configure would create the subdirectory in the build dir and template out the Makefile.in into e.g. `build/enc/Makefile`. However, we don't use recursive make, so we don't call `AC_CONFIG_FILES([enc/Makefile])` or anything like that. (There is actually an `enc/Makefile.in`, but it's templated by a Ruby script, not by autoconf). Has anybody else noticed this? -- https://bugs.ruby-lang.org/

Also note that having an in-place build and an out-of-src build at the same time doesn't work. Maybe that's what you're seeing.

Exactly this - now I feel stupid. I thought i'd `make clean`'d my previous in tree build, but `.ext/.timestamp` was still there. Of course, then for my out of tree build, make sees that and thinks the target is up to date, so this rule never runs: ``` $(ENC_TRANS_D): $(Q) $(MAKEDIRS) enc/trans $(@D) @$(NULLCMD) > $@ ``` I must have just done something strange. I did an in-tree build just now, followed by `make clean` and then an out-of-tree build, and it worked.
