Arrgghhh. File1: class A { ... } // Constructor and Destructor A a; class B { ... } // Constructor and Destructor class C { ... } // Constructor and Destructor extern C c; main() { B b; } File2: class C { ... } // Constructor and Destructor C c; When File1 is compiled on its own the constructor for a is called before the main starts etc. As expected. However, if File2 is compiled and linked in and it is first to the linked then the constructor for a is not called at all! If File2 is compiled and linked in but File1 is first to be linked then the constructor for a is called but not the constructor for d. What is the story? It seemed to occur with Version 1.2.1 and Version 2.0. Seems to me to have something to do with linking the STI-functions together via the LINK structure. Is this the responsiblility of mxx/c++patch? I was under the impression all of the constructors would be called before the main program. What could be happening to cause this? Am I mad? Any information which can enlighten me on this subject will be most appreciated. Please e-mail me (as well if you post) as I don't want to miss any answers.
