Not having a make that knows about RCS is a real pain. As far as I
can tell, I need to explicitly state dependencies between RCS/foo.c,v
and foo.c for all files in my project. This works, but it has the
unpleasant side effect of spewing forth warnings about infinite
loops (because the dependencies go both ways -- one for checkin and
one for checkout). I tried to set up default dependencies with
.SUFFIXES, but that didn't seem to work out too well either. Somehow,
I feel there must be an easier way. Can anyone suggest one to me?

Somehow, >I feel there must be an easier way. Can anyone suggest one to me? We get around that by not using RCS sub-directories (the ,v files are kept in the same directory as the sources). Then a simple production for .c,v.c: works fine. We build our system from ,v files and only do checkins manually, therefore our make system never has to do checkins (I can't help you with your infinite loop problem). -maddog

When you say "that knows about RCS," do you mean your make doesn't have rules like .c,v.c defined? That's probably too simple an explanation. Does your make understand .PREFIXES? If it does, you can put the following line in your makefile. If make doesn't find a .c,v file in the current directory, this tells it to check the ./RCS directory as well: .PREFIXES: ./RCS You can add other directories (like /usr/project/RCS) at the end, too. --Jerry Peek, Northeast Parallel Architectures Center, Syracuse, NY jerryp@cmx.npac.syr.edu +1 315 443-1722

Yes, I don't have a make that has builtin knowledge of the RCS directory and rcs commands. I received several replies about this via email and almost all said "use gnumake". I probably will end up doing that. I never did hear anything about the .PREFIXES dependency, although I heard about the VPATH variable. You can use this to set a search path just like the shell PATH variable. Interestingly enough, the system I'm developing on (Sun 4 with SunOS 4.0) has a make that has the VPATH variable mentioned in strings output, but it is not documented and it doesn't seem to work. Like I said, I'll probably start using gnumake, since this is only for my own benefit -- the distributed program will use a different makefile. Mark D.

I've heard about gnumake but don't know where to get it. Can you tell me?
