Create library question

YE LIU_1 — Thu, 11 Jun 2009 13:22:35 GMT

Dear VMS Users,

How can I do it in a command line if I have an object file: foo.obj and I want to add foo.obj to test.olb with name bar?

Thanks,

YE LIU

Set the module name within foo.whatever source as bar. Syntax varies by language.

If you want both foo and bar together, you'll likely have symbol name collisions.

YE LIU,

what problem are you trying to solve ?

The name of the module (in case of an object module) is derived from the object module header inside the .OBJ file (see ANAL/OBJ)and not from the filename of the .OBJ file or from some other qualifier given to the LIBR command when inserting the .OBJ file into the .OLB library.

Hi, All

Thanks for your reply. I thought I need to do this when I saw in the original MMS file, there is a line:

libraries:-
$(CFTSD_OLB)(cvt_price_d=$(OBJDIR)cvtpd_fsm.obj)

I think cvtpd_fsm.obj will be module cvt_price_d in library $(CFSD_OLB). Am I right?

Also, I have question on MMS: it seems that MMS allows different module of a library as an entity like:

TEST.OLB(foo=foo.obj): foo.obj

but in make, you can only use the library as an entity. How to convert this case to make from MMS.

Thanks,

YE LIU

Sounds about right. It's possible to have a
module name which differs from the name of
the object file. ("rename x.obj y.obj" or
"cc /object = y.obj x.c", for example.)

Is this true? Perhaps there's a reason to
use MMS. (Did you ever say which "make" you
were using?)

I still don't know why you're doing this. It
seems like much work, and I don't know what
the reward is supposed to be.

hi, Steve

The make is GNU make.

Well, that's one question answered. Does it
have a version number?

Hi,

First you need to change the module name of the object using the appropriate language directive

For example in C language, "#pragma module" directive would do it

#pragma module bar
main()
{
printf("hello");
}

Here is the MMS equivalent you need to create the object library from this module

$ type descrip.mms
test.olb : test.olb(bar=hello.obj)
libr/repl test.olb hello.obj

Are you trying to do the same using Make utility.

Regards,
Pramod.

Gnu make allows "archive" members as target, see the manual, as in
http://www.cs.utah.edu/dept/old/texinfo/make/make.html#SEC101

For example

$ ty makefile.
test.olb(bar): foo.obj
$(AR) $@ $<
$
$ gmake -v
