extern Class

k.o.g.(Posted 2014) [#1]
Hi, i'm working on a c++ Socket Library,
so i use the extern 
	Class sockaddr_in Extends sockaddr
		Field sin_family:Int
		Field sin_port:Int
		Field sin_addr:in_addr
		
		Field sin_zero1:Int
		Field sin_zero2:int
	End


And now, i want to use debug mode, but transcc gives me the following error:
main.cpp: In instantiation of 'String dbg_value(T*) [with T = sockaddr_in*]':
main.cpp:1383:27:   required from 'String dbg_var_type_t<T>::value(void*) [with T = sockaddr_in*]'
main.cpp:3771:1:   required from here
main.cpp:1351:38: error: cannot dynamic_cast '* t' (of type 'struct sockaddr_in*') to type 'class Object*' (source type is not polymorphic)
main.cpp: In instantiation of 'String dbg_value(T*) [with T = WSAData*]':
main.cpp:1383:27:   required from 'String dbg_var_type_t<T>::value(void*) [with T = WSAData*]'
main.cpp:3771:1:   required from here
main.cpp:1351:38: error: cannot dynamic_cast '* t' (of type 'struct WSAData*') to type 'class Object*' (source type is not polymorphic)


the final code of the project:
	sockaddr_in* t_Address=(new sockaddr_in);
	DBG_LOCAL(t_Address,"Address")



Any chance to set a extern class to "nodebug" infos?

I believe what you try to do is not possible because your object class cannot extend your struct .
Depending on your context it might be a good idea to only expose the Methods (Virtual?) of your class to Monkey.

The problem is, i work with socket structs.
Monkey want create a debug value of the extern struct, but this is not of the type gc_object.
It would bi great, when i can declare a extern class to nodebug...
I think, i must rewrite transcc...

You could take a look @ MonkeyX\modules\brl\native\socket.cpp and MonkeyX\modules\brl\socket.monkey to see how the original socket implementation looks like.

I do not see a possibility to get the struct thing to work out of the box.
Best way is probably to convert your struct into a class or to put it in a class.(Or try the Adapter)
Alternatively you could hide the struct completely from Monkey X and only Expose Functions or Methods which perform actions without Monkeys knowing.

I don't know exactly what you are doing but it looks like to me you are trying to create a class which is no Monkey X Object.
In this case try to extend null:
Class MyClass Extends Null="MyC++ClassName"
End
