Re: Evaluating Target Name

[Luke Shumaker]

I'm not entirely clear if this is the situation you're in, but:

default::

-include md5sums.mk
md5sums.mk: md5sums
        sed 'address@hidden \([^ ]*\)@default :: \1\n\1: $<@' < '$<' > '$@'

# END #

Which would make the `default' target depend on all files listed in the
file `md5sums' and make each of those depend on `md5sums'. (The sed
script breaks on filenames with spaces... but so does make, so it's OK)

I hope this helps.
