Multiple inheritance problem

I’ve been staring at this cryptic error message for far too long, so I’m hoping that some other jucer can show me the light. The error looks like this:

maincontentcomp.cpp(50) : error C2385: ambiguous access of 'delete’
could be the ‘delete’ in base 'juce::Component’
or could be the ‘delete’ in base 'juce::ApplicationCommandTarget’
This diagnostic occurred in the compiler generated function ‘void *mainContentComp::__delDtor(unsigned int)’

and the maincontentcomp class is defined:

class mainContentComp :
public Component,
public ActionListener,
public ActionBroadcaster,
public Timer,
public MenuBarModel,
public ApplicationCommandTarget

this code compiles under Xcode, but chokes under VS, if that helps.

you need to have the ‘juce_UseDebuggingNewOperator’ in your class declaration.

Bingo! Give the man in the back a prize.

I’m going to spend the rest of my day gluing my hair back on.

Thank goodness for the forums! I also was staring befuddled at this compile error when inheriting from multiple JUCE classes. To help others in the future, here’s a simple example that works:

[code]#include “juce.h”

class blah : public Component,
public DragAndDropContainer
{
public:
blah();

// Magic to eliminate multiple inheritance problem regarding ambiguous use of
// delete in blah::__delDtor
juce_UseDebuggingNewOperator

};

blah::blah()
{

}
[/code]

After the excitement of successful compilation dies down, I’ll have to dig into this to understand what’s going on…
