text_io is not a predefined library

text_io is not a predefined library

[Andrew Busolin]

Hi there,

I have written a little hello world program in an effort to test out the ada
compiler I have recently downloaded. I am able to compile it using
gcc -c -gnats -c hello.adb, however when I try to gnatmake it using
gnatmake -c hello.adb it returns "ada.text_io" is not a predefined library
unit
compilation abandoned!!!

Can someone please tell me why this is and how I can fix it!

Best Regards

Andrew Busolin


with Text_Io;
use Text_Io;

procedure hello is
begin
Put("hello");
end hello;

Hmm...What target and OS? Sounds like a broken install...
Also the correct way to build is

gnatmake hello

no .adb no -c

Text_Io is a child of Ada.

Try:
  with Ada.Text_Io;
  use Ada.Text_Io;

Steve,

I have tried using

 with Ada.Text_Io;
 use Ada.Text_Io;

however still get the same response! For some strange reason I think it is
not finding the library! The file however does exist in the adalib
directory. I am using the gnat310 compiler. Do you have any other thoughts
that may help me?

Best Regards

Andrew

Re: text_io is not a predefined library

[David C. Hoos, Sr.]

Using Text_IO in place of Ada.TextIO is not the problem.

Note the following from RM95, J.1;
The following library_unit_renaming_declarations exist:

2 with Ada.Unchecked_Conversion;
generic function Unchecked_Conversion renames Ada.Unchecked_Conversion;
3 with Ada.Unchecked_Deallocation;
generic procedure Unchecked_Deallocation renames Ada.Unchecked_Deallocation;
4 with Ada.Sequential_IO;
generic package Sequential_IO renames Ada.Sequential_IO;
5 with Ada.Direct_IO;
generic package Direct_IO renames Ada.Direct_IO;

6 with Ada.Text_IO;
package Text_IO renames Ada.Text_IO;
7 with Ada.IO_Exceptions;
package IO_Exceptions renames Ada.IO_Exceptions;
8 with Ada.Calendar;
package Calendar renames Ada.Calendar;
9 with System.Machine_Code;
package Machine_Code renames System.Machine_Code; -- If supported.

The earlier suggestion by Jeff Creem that it is a GNAT installation
problem is the correct explanation for the phenomenon.
