I have the following:
- A library called toto.so where the object Toto is implemented:
class Toto
{
public:
Toto();
static Toto *instance() { return self; }
private:
static Toto *self;
};
- A main.cpp linked against toto.so:
int main()
{
Toto tmp;
std::cout << "Main: Toto::instance() == " << tmp.instance() << std::endl;
return 0;
}
If I build everything like this:
g++ -shared -fPIC -Wl,--dynamic-list-cpp-typeinfo toto.cpp -o libtoto.so
g++ -Wl,--dynamic-list-cpp-typeinfo main.cpp -L. -ltoto
The toto::instance() function returns 0 in the main function.
However, if I build without --dynamic-list-cpp-typeinfo, the toto::instance()
function returns the correct value.
I compiled natively on Linux I386 and I cross compiled for ARM.
I got the same results on both architectures.
