Hi -
Using Boost 1.53.0, the following code fails to compile with g++, when
c++11 is enabled:
#include
#include
struct A{}; struct B{};
typedef boost::variant my_variant;
void foo(boost::python::object o) {
my_variant v = boost::python::extract(o);
}
The error is:
/home/bcatanzaro/boost_
Thanks Jim, adding the extra parentheses solved the problem.
I'll contact the Boost.Variant people.

Have you tried using boost::enable_shared_from_this? The following example code
seems to do what you want.
