text_io is not a predefined library

["Andrew Busolin" <abusolin@chariot.net.au>]

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;
