GNAT installation ?

GNAT installation ?

[Richard Pitre]

I'm having a little trouble getting started with GNAT 
for NeXTStep (UNIX BSD 4.3).
the gcc version is 2.7.2 and I think that GNAT version is 3.01a

I compiled this exercise 1.2a from Cohen's book
******************************
with Ada.Integer_Text_IO;

procedure Sum_3_Inputs is
-- This program reads in three numbers
-- and prints out their sum
A,B,C: Integer;

begin
  Ada.Integer_Text_IO.Get(A);
  Ada.Integer_Text_IO.Get(B);
  Ada.Integer_Text_IO.Get(C);
  Ada.Integer_Text_IO.Put(A+B+C);
end Sum_3_Inputs;
******************************

When I run gnatbl, I get the message:

ld: Undefined symbols:
_getcwd

Any clues.

gnat RTL on NeXTStep uses POSIX routines.  Use -posix flag on
gnatbl; e.g.,

>gnatbl -posix -o sum_3_inputs sum_3_inputs.ali

There should be a README.NEXT file in your distribution which
explains this.
