libgtkada2.14.2 on Ubuntu 10.04

libgtkada2.14.2 on Ubuntu 10.04

[John B. Matthews]

In preparation for porting a GtkAda application to Linux using 
libgtkada2.14.2-1, I tried a simple example [1] on Ubuntu 10.04.1.

I was surprised to see this

$ gtkada-config --cflags
-aI/usr/share/ada/adainclude/gtkada2.14.2 \ 
-aO/usr/lib/ada/adalib/gtkada2.14.2

when the actual locations are these

/usr/share/ada/adainclude/gtkada2
/usr/share/ada/adainclude/gtkada2

Now that I look, it's been fixed [2], but I'm not sure of the best way 
to resolve the problem: add another repository or just edit 
gtkada-config.

Sorry of this is off topic.

Is it impractical for you to use GNAT project files?  The Debian
compiler is patched so that

with "gtkada";
project Example is
   for Main use ("example");
end Example;

will work out of the box; see the file
/usr/share/ada/adainclude/gtkada.gpr.

Another option, of course, is to ditch the man in the middle (Ubuntu)
and go straight to the source of the correct package: Debian.

Oops, I meant "/usr/lib/ada/adalib/gtkada2".

Excellent! It works well; thanks. Am I correct that 'with "gtkada"' 
refers to /usr/share/ada/adainclude/gtkada.gpr itself?

with "gtkada2";
project lady is
   for Object_Dir use "obj";
   for Exec_Dir use ".";
   for Main use ("main");
end lady;

Tempting.

Yes, correct.  When I said the compiler was patched, it was so that it
looked in that directory, by default, for project files.

The big advantage of Debian is that it requires that each library
provide such a project file; thus it is trivial to use all libraries
that you need in the same program: simply add more with clauses to your
project.

Ah, I see what you mean:

$ gnatls -v

GNATLS 4.4.3
...
Project Search Path:
   <Current_Directory>
   /usr/share/ada/adainclude/

$ ls -l /usr/share/ada/adainclude/
