Hello,
I found my constructor problem and thought I'd share it with you all.
I am compiling two directories into intermediate objects. Both directories contain
mixed C and C++ files. Then at the last stage of compilation I link the two
intermediate object files togehter.
It is in the last stage of linking that you must do the $(CRTBEGIN) and $(CRTEND)
stuff. I leave the first linking stages as "normal" (i.e. without these CRT macros)
and just leave it up to the last step.
As an aide, before trying anything else to fix a C++ program that crashes, make sure
constructors are working. You can do the following as a quick test:
// globals
int foo=1;
typedef struct
{
int & foobar
}test_ctors_t
test_ctors_t test_struct = { foo }
some_init_code()
{
assert(&test_struct.foobar == NULL)
}
I think I'm going to refine this and put it in my code as a runtime check...It just
seems to rear its ugly head and the symptoms aren't always easy to spot, your program
simply crashed on null pointers. Hope this helps someone.
Thanks,
~Ken
