Steve,

I'm not sure why this does not work. The only difference I can think of (from some of things that I am doing) is that all of my rules and actions are in the top Jamrules file, rather than the Jamfile?

Sorry I can't be of more help right now

Brett

I'm still a little baffled by this, but I have figured one more thing out. Adding grist within the rule doesn't work, but if the caller adds grist manually it works fine:

DEPENDS [ FGristFiles $(<) ] : $(>) ; #doesn't work,

DEPENDS $(<) : $(>) ; along with CatRule foo.c : foo.txt ; #works

Is there anyone out there who could explain this to me? Obviously I'd prefer not to have to add grist manually each time. How do I go about creating a rule that works as expected with the SubDir command?

Thanks,

Thanks. That helps, but I'm still not quite getting it. Jam doesn't complain about not knowing how to make foo.c any more, but it won't make it either, even though it appears to know how. If I run jam, it tries to Cc Sub/foo.o, but fails because foo.c doesn't exist. If I type 'jam foo.c', it creates jam.c but issues the "warning: using independent target foo.txt". After that, jam will build foo.o and foo just fine.

Interestingly, if I then 'touch foo.txt', that will cause jam to remake foo.o (from the out of date foo.c). It won't ever make foo.c if it already exists (even with an explicit 'jam foo.c').

My updated Jam file, and some output from jam -d is below. As before, it works fine without the SubDir command. Any help is appreciated. Thanks.
