This is the case for all the global variables (and static members are global).
By the way, it's not a good idea to share other things than pointers,
Dll can shre only pointers. Here you have no warning message because
your variable (int) has the same size than a pointer.
Try to share an object to see.
A solution is to do :
tbar *Foo_bar;
class Foo {
public:
static void init();
static void done();
};
void Foo::init()
{
Foo_bar = new tbar(17);
}
void Foo::done()
{
delete Foo_bar;
}
int main()
{
Foo::init();
printf("Foo::bar=%d\n", *Foo_bar);
Foo::done();
return 0;
}
