Hi All,
I tried to build a basic package. My two files look like this:
File 1: basic_num_io.ads
package Basic_Num_IO is
procedure Num_IO;
end Basic_Num_IO;
File 2: basic_num_io.adb
with text_io; use text_io;
package body Basic_Num_IO is
procedure Num_IO is
package Integer_InOut is new Integer_IO(integer);
package Float_InOut is new Integer_IO(float);
begin
null;
end Num_IO;
end Basic_Num_IO;
If I call gnat compile basic_num_io.ads I get the error message:
basic_num_io.ads:8:01: end of file expected, file can have only one
compilation unit
What am I doing wrong? Where can I find it in the documentation?
Kind regards
George

basic_num_io.ads clearly has at least 8 lines in it, not the 3 you presented.
Since I don't know what's in this file, I can't really help you. Make sure this
file only contains the package specification.
In general, you don't need to compile the package specification; that's done
automatically when you compile the body.
gnatmake basic_num_io.adb
should do that for you, once you get the contents of the files correct.

The documentation depends on which version of GNAT you're using. Documentation
for GNAT GPL 2011 is at
http://www.adacore.com/category/developers-center/reference-library/documentation/

Hmmm... It complains at line 8, but what you show has only 3 lines.
There must be something else that you didn't notice at the end of the
file, and the compiler considers that something as a second compilation
unit in the same file.

Hi Jeffrey,
Hi Jean-Pierre,
you're right: I left my comments out.
I started all over, deleted both files and build a new file with just the
three lines in it:
package Basic_Num_IO is
procedure Num_IO;
end Basic_Num_IO;
The compiler error is now
gcc-4.3 -c basic_num_io.ads
cannot generate code for file basic_num_io.ads (package spec)
to check package spec for errors, use -gnatc
gnatmake: "basic_num_io.ads" compilation error
I tried gcc-4.3 -c -gnatc basic_num_io.ads. No error occured.
How can I fix that?
Kind regards
George

As someone above pointed out, GNAT won't generate object code from a
spec (unless the spec doesn't need, ie must not have) a body. Try
compiling the .adb file.
-gnatc is "Check syntax and semantics only (no code generation)". I
found this out using the command "gnatmake -h".
You're better off using gnatmake as the compiler driver, it understands
all about dependencies and the Ada bind/link process, and will produce
executables if it can.

Hi Jeffrey,
Hi Jean-Pierre,
I tried again and checked my code. The reason for the error is a wrong
call to a function. It should read
package Float_InOut is new Float_IO(Float);
instead of
package Float_InOut is new Integer_IO(Float);
Many thanks for your willingness to help.
Kind regards
George
