Hi all,
I'm trying to use a C++ library from Perl using Inline::CPP. The problems I've found so far
can be reproduced with the simple program below.
1. virtual destructor is not supported
2. The Editor::Copy() method clashes with some other from the Perl library (handy.h?)
Thank you for any help.
- Subir ----------------------------------------------------------------------------------------------------------------------------------- use Inline CPP;
my $e = new Editor; $e->cut;
__END__ __CPP__
class Editor {
public:
Editor() {}
~Editor() {} // Does not seem to support virtual destructor
virtual void Print();
virtual void Cut();
virtual void Copy(); // handy.h has another Copy()
virtual void Paste();
};void Editor::Print() {
cout << "Object (" << this << ")" << endl;
}
void Editor::Cut() {
cout << "Cut text" << endl;
}
void Editor::Copy() {
cout << "Copy text to buffer" << endl;
}
void Editor::Paste() {
cout << "Paste text from buffer" << endl;
