Hi. I have alot of Makefiles that call a "makedep" or "mkdep" program, which
I assume adds to the end a zillion dependencies, like:
main.c: header.h defs.h structs.h
other.c: structs.h
another.c: defs.h header.h
And so forth. Anyway, I could really use this program, or one which does
something similar, for those Makefiles and as a general utility. If
anyone has any information about one of these, please let me know where
I can ftp or uuencoded mail it from.
Thanks
Doug

[ OK guys, where *do* you ask about things like makefile makers ? comp.unix.programmer ? alt.sport.toe.wrestling ? I'll try the former :-) ] [ Now I'm going to *expect* a followup telling me what the current crop of mkdeps do that cc -M doesn't. Or do people distribute makedepend just because some people don't have cc -M ? Answers on a postcard to Craig Shergold, please, or follow up :-) ] fields-doug@cs.yale.edu (Doug Fields) writes: > Hi.

One fast and accurate way to make dependencies for makefiles is to use gcc -M. (Doug's asking about Xenix/Sys V, so he'd need gcc. BSD cc has -M doesn't it?) For example, you could add something like depend: sed "/^# DELETE ME/q" Makefile > Makefile.new gcc $(CFLAGS) -M $(OBJS:.o=.c) >> Makefile.new mv Makefile.new Makefile # DELETE ME to the end of your makefile. Then "make depend" would do just that. This works especially well when your dependencies change a lot depending on what -I and -D flags you change in CFLAGS, just run make depend again. Just make sure you haven't got a file called "depend" in the current directory :-) -- ronald@robobar.co.uk +44 81 991 1142 (O) +44 71 229 7741 (H)
