Can't get my program linked '-static'

[Rudolf Schubert]

Hi Gaius,

you remember the tarball I sent to you back in April? Things are running
fine now. Even the three 'bug versions' do not have problems any more.
That's really great!

What I now try to do: get a static binary. But for some reason it does not
work. For dynamic linking I use this command which is working perfectly:

> gm2 -fiso -fsoft-check-all squash1.mod Ctv2.o unix.o -o squash1 -lc -lcrypt 
> -lm

Now for static linking I simply append a '-static' at the end:

> gm2 -fiso -fsoft-check-all squash1.mod Ctv2.o unix.o -o squash1 -lc -lcrypt 
> -lm -static

But this gives me several messages like:

...in function `m2iso_RealMath_exp':
...undefined reference to `exp'

Interestingly 'sqrt' ist NOT mentioned, which is the only function from
RealMath which I use in my program.

If I just make a very tiny test program like this I can do
-static linking without any problem:


MODULE port_test11_gm2;

FROM IOChan IMPORT
  ChanId;
FROM RealIO IMPORT
  WriteReal;
FROM RealMath IMPORT
  sqrt;
FROM StdChans IMPORT
  StdOutChan;
FROM TextIO IMPORT
  WriteLn;


PROCEDURE RealMathTest();
  VAR
    cid_out:                    ChanId;
    r1, r2:                     REAL;

  BEGIN                         (* PROCEDURE RealMathTest *)
    cid_out := StdOutChan();

    r1 := 16.0;
    r2 := sqrt(r1);
    WriteReal(cid_out, r2, 1);
    WriteLn(cid_out);
  END RealMathTest;


BEGIN                           (* MODULE port_test11_gm2 *)
  RealMathTest();
END port_test11_gm2.


Would I have to change my command line in order to do static linking
or what might be the reason that it does not work?

Rudolf
