Trig Function Linking Problems

["AJAskey" <AskeyAJ@gmail.com>]

Hi.  We are moving some software from and ancient workstation to a
newer one.  The environment is still several years old but newer than
the old-timer we are leaving.  We cannot get the TRIG functions to
work as there appears to be a problem interfacing to the library.  The
following test code works on the old-time system, but fails on two
separate newer systems.  Any help would be greatly appreciated.

with ada.text_io;
  use ada.text_io;
with ada.numerics.elementary_functions;
procedure TRIG is
  a,b,c,d : float;
begin
  a := 3.1415/4.0;
  b := ada.numerics.elementary_functions.sin(x=>a);
  c := ada.numerics.elementary_functions.cos(x=>a);
  d := ada.numerics.elementary_functions.tan(x=>a);
  put_line("sin(a)" & float'image(b));
  put_line("cos(a)" & float'image(c));
  put_line("tan(a)" & float'image(d));
  put_line("a     " & float'image(a));
end TRIG;

[I tried linking in the -lm library which is required in the "c"
version of this test.  I also tried linking a few others, but
continued to get the run-time error.

On another similar system, the program ran but returned NaN in the
debugger for b,c,d after the sin,cos,tan calls.  I assume it really
isn't finding the library.]

>>gnatmake -c trig.adb
>>gnatbind -x trig
>>gnatlink -lm -lc -lgnat trig

>>trig

Any ideas what I should be linking in?

Thanks much.
