Eh? I can't find any. We have things like
setSourcePackage(PackageSpecification(name));
which at the end of the call chain does:
_packageversion::setSourcePackageSpecification(PackageSpecification
const &aSpec)
{
_sourcePackage=aSpec;
}
which should not invoke the copy contructor. rather it is the assignment
operator.
PackageSpecification &operator= (PackageSpecification const &);
which is public, and should be usable.
gcc 3.x have all honoured the privateness of Foo aFoo(Foo());, and
whatever warning you are getting is probably correct.
As to the privateness of the copy constructor, I didn't comment it, but
neither did I implement it: thats an idiom I use, to cause compiler
errors when someone tries to do something that they aren't meant to.
You could certainly make it public and implement it if you choose.
However, showing the error you get might be more useful...
