Subject: Translate Makefile to MMS file

I am trying to do a port from UNIX to VMS. I have a program written in
straightforward vanilla C. I've compiled it with a Makefile in AIX,
Solaris,
and Linux. I want to compile it in DECC, but I don't know how to
translate
the Makefile to an MMS file. I have the MMS documentation, but I'm
having
trouble getting started, especially with libraries. I boiled the big
Makefile down to a small example that contains most of the important
issues.
I've listed it below. I would very much appreciate it if you could
translate
that Makefile to an equivalent MMS file. Once I see how that's done, I
think
I could do the big one myself.

A short description of what it does.  The files alpha.c, beta.c, gamma.c
are
compiled and put into a library lib1.a. Three programs are produced: 
        xxx from xxx.c
        aaa from aaa.c with DAILY=0 and bbb.c
        sss from aaa.c with DAILY=1 and bbb.c
All are linked with lib1.a. Everything depends upon the h-files eee.h,
fff.h, ggg.h.

Thanks very much.

Hello Nishan Krikorian

I think it's possible to do what you want.  I hope I understood correctly; here
is the MMS file I came up with.

I haven't made much use of built in rules, so hopefully it is fairly clear
what's going on.

A couple of points:

The ".first" directive is needed because you want to make sure that "lib1.olb"
exists, otherwise the "library/replace" commands used to update the library
will fail.

I have to have a dependency in to make the whole library depend on all its
contents. This doesn't have any direct actions (just a comment as you see), but
it does mean that MMS then goes and does all the actions needed to make sure
the contents are OK.

Similarly, I put a dependency in at the top ("all").  This is so that by
default, MMS will build all the executables, although there's no direct action
that occurs from this (you just have to have a line of DCL there otherwise it
complains).



Let me know if you have questions or if I've misunderstood what you were trying
to do
