Here's what I've got so far. It's broken and I have a few questions:
- what's if %?SUBDIRS% ... endif for? I've seen it used elsewhere, and
comments that say it's not allowed.
- is there a better way to do what I'm doing with
$(MAKE) ... reldir=$$subdir cscopedirs
? the cscope.files file in $(top_builddir) needs to have paths relative
to $(top_srcdir) (and, come to think of it, my current approach doesn't deal
with that at all)
- when I run automake to recreate my makefiles, some directories are missing
'cscopedir' rules, how can I check for that?
Thanks,
Jesse
