Line 60: void __cxa_finalize(void f); </source> ~~==== Versions before GCC 3.2 ====~~ GCC inserts an array of pointers into the object file. Look for the ELF section called '''ctors'''. Each pointer indicates the constructor of a global / static object. Your Assembly start-up code should call them in turn before passing control to your C++ kernel code. There also is a '''dtors*''' list of destructors. If your kernel returns, the shutdown code should also call them in turn. Remember to destruct your objects in the '''opposite''' order you have constructed them (for the sake of inner dependencies). ~~Additionally, you should see the [[C++ Bare Bones]] tutorial for more information on how to call static constructors.~~ ==== Versions after GCC 3.2 ====
