Hi ,

we know that rb\_funcall , is used to call some Ruby Methods from the C  
code ,  
actualy , This is what I tried , but in my case , it doesnt seem to work

my case is , that I should call a Ruby Method from a Ruby Class that  
inherite from another Class.

with a Simple Ruby Class

class MyClass {  
def initialize()  
&nbsp;&nbsp;&nbsp;puts "bla bla bla"  
end  
end

rb\_funcall3(rb\_const\_get(rb\_cObject, rb\_intern("MyClass")),  
rb\_intern("new"), 0, 0); // Works Good !!

But If I have

class MyClass \< AnotherClass

def intialize ()  
&nbsp;&nbsp;super()  
&nbsp;&nbsp;puts "alb alb alb"  
end  
end

the rb\_funcall Stucks !!  
ruby: allocator undefined for MyClass (TypeError)

Can SomeOne Help ??

Thx 😉
