[orbitcpp-list] CORBA_long_double type

[Sam C. <sa...@to...>]

G'day all.

I'm working on implementing Any in ORBit-C++, but have a problem.

The C++ mapping spec says that the CORBA::LongDouble type must be distinct
from other types for the purposes of overloading functions.
CORBA::LongDouble is typedef'd to ORBit's CORBA_long_double type, which is
in turn typedef'd to glib's gdouble type. CORBA::Double is likewise
typedef'd to ORBit's CORBA_double type, which is also typed to glib's
gdouble type. So the compiler can't tell them apart, and thinks the Any
insertion operator for CORBA::LongDouble is a redeclaration of the insertion
operator for CORBA::Double.

That's no good.

I tried changing the typedef for CORBA_long_double to "long double" (I would
have used glib's gldouble if it had been defined) and rebuilding ORBit, but
now if I try to send CORBA_long_double arguments I get garbage. I can't see
anywhere that has a size hard-coded. Yes, I rebuilt the IDL compiler as
well, and regenerated the stubs and skeletons with that.

Can anyone help me make CORBA_long_double a distinct type from CORBA_double?
Or more importantly, make CORBA::LongDouble distinct from CORBA::Double?
I don't really want to write a CORBA::LongDouble class and implement all the
standard arithmetic operators. :(
