Problem with child package

Problem with child package

[DELROEUX JEAN-YVES]

Hello, I explain my problem :
I define a type carav is new voiture in a child package of the package
voiture. But when i define a global variable of this type (carav), the 
compiler ( gnat 2.00 under OS/2 Warp ), It says no errors. But when I want
to use it into procedure of another package, The compiler said a lot of errors
The errors says that it's doesn't know the veriable I define ??

But it work correctly if I pass this variable as parameter into each 
procedure . Does it mean that I can't define a global variable when the type
is defined into a child package. Can someone help me please.

	Thanks for your respond.

	DELROEUX Jean - Yves

<discription of carav and voiture packages and child packages>

Remember that there are many scopes in Ada, not just 'local' and
'global. In which package did you declare your 'global' variable? That
package must be visible (via 'with' and possibly 'use') at the point
you want to use the variable.

For example:

package voiture is
	type carav_1 is ...;
end voiture;

package voiture.child is
	type carav is new carav_1 ...;

	global_var : carav;
end voiture.child;

with voiture.child;
procedure access_global_var is
begin
	voiture.child.global_var := ...
end access_global_var;

If your code looks different, post some of it, maybe that will help.

Jean-Yves, if you have a problem with GNAT, please follow the documentation
and submit a query, with full sources, to gnat-report.

Sorry to keep posting these reponses, but this seems like an IFAQ
(incredibly frequent asked question).

In general, always send sources, from your vague description I can't even
guess what you might be doing wrong.
