Here's another problem. When we change the OS not only must we setup the compiler, environment and such but sometimes an OS API could be deprecated or removed. You made mention of a possible OS change so that's a possibility. You obtained this code from somewhere. Go back there and see if they updated it for your new OS.

That is a nice little find. I didn't know that shared-ptr had this behavior built-in. But now that I think about, it makes perfect sense. One of the required features of shared-ptr is to be able to share ownership of one object through different shared-pointers which could be different kinds of pointers (to different base classes or data-members), …

If you having any integer or pointer variable, call it `a`, then writing `if( a )` is equivalent to writing `if( a != 0 )`, because any non-zero (or non-null) value converts to `true`, so, `if(a)` is true as long as `a` is not equal to zero. > I thought the …

We need more detail. You say you are using a custom version of shared-ptr, and the error seems to be in that custom class. So, we need to see that code, otherwise there is really no way to tell where the error might come from.

`ptr` is an object of type char*. `&ptr` is a pointer to the object ptr, so an object of type char** (pointer to a char pointer) `*&ptr` is the object that `&ptr` is pointing to, so it's ptr again.

ptr[i] is not a pointer, so you need to use the dot operator . SetState() only needs one parameter, now twom In main() you would write this: for(int i = 0; i < 100; i++) A[i].setState(n); And setState() simplifies to just one line void State::setState(int num) { *state = num; }
