ld warning: PA 2.0 obect file

Michael D. Zorn — Mon, 12 Mar 2007 18:19:03 GMT

The warning is

ld: (Warning) At least one PA 2.0 object file (pgm.o) was detected. The linked output may not run on a PA 1.x system

I don't think I need to worry about that - there's only one machine here. Is there a way to suppress that warning?

We compile and link through the compiler, f90, with makefiles. The compile line is

f90 -o pgm pgm.o -lingres -lm

(-lingres is the database library)

Hi:

You should be able to suppress this by adding the '+vnocompatwarnings' flag during linking.

That aside, this is only a warning and hence is advisory only.

Regards!

Right. This warning was more important back in 1996 when PA2.0 was introduced. Now, most PA1.1 machines are no longer supported.

somewhere in my cellar, an A180C is silently weeping.

I found I could give it to f90 to hand off to the linker:

f90 -Wl,+vnocompatwarnings .....

and that other options (like -g) need to come after the -W

Thanks again.

>f90 -Wl,+vnocompatwarnings

Yes, that's how to pass linker specific options.

>that other options (like -g) need to come after the -Wl

I doubt there is any restriction on the ordering of this -Wl option. Just as long as it is passed to ld. You should be able to see this with -v.

My makefile line is
FFLAGS=-Wl,+vnocompatwarnings, -g

The reason I got an error message was that I had

FFLAGS=g, -Wl,......

No commas between options.... but seems OK at the end: , -g

You can't have commas in options, just whitespace. There is a comma after -Wl and between options for ld, etc.:
-Wl,-B,immediate

In the case of -Wx, each comma is replaced by a space.

The solutions provided did the trick.
