Re: How to tell an extra rule to automake

This means 'ttimes.f must be up-to-date in order for this rule,
which makes modnam.def up-to-date, to be able to run'.  From what
you say, this is not what you mean.

Then what you need is:

# The double :: forces it to be rebuilt each time
modnam.def::
        echo "       data modnam/'$(datadir)'" > modnam.def

ttimes.f: modnam.def


I'm not sure if automake will still generate a compile rule for
ttimes.f, so you may need to specify the compile command as well.
