Subject: Export to a Namespace?

Message-ID: <3D948F1F.9A87CE48@boeing.com> (raw)
I'm supporting a large mass of legacy Ada and my boss wants to add new
functions using C++. There are about 2000 constants defined in the Ada
code that we'll need visible to C++. Not a problem, a quick Perl script
will add a pragma Export after each declaration. The values being
exported are resolved at compile time, otherwise I'd just duplicat the
declarations in C++.
BUT, our system architect is a stickler about not polluting the global
namespace, so can I export from Ada to a C++ namespace? Perhaps
something like (though this won't compile on my Green Hills compiler):
C++ Side:
namespace My_Wrapper {
extern int First_Val;
extern int Next_Val;
}
Ada Side:
First_Val : constant integer := Some_Withed_In_Named_Number;
pragma Export(CPP, First_Val, "My_Wrapper::First_Val");
Next_Val : constant integer := First_Val'Succ;
pragma Export(CPP, Next_Val, "My_Wrapper::Next_Val");
Any help would be much appreciated, even if it's just a "You can't do
that"!
Thanks
Jeremy
