Hello,
I've just started playing around with BLL and i have some
troubles using it with containers of shared_ptr. I have
isolated the problem to:
void lambdaTest() {
using namespace boost::lambda;
boost::shared_ptr<int> x(new int(5));
(*_1)(x);
}
This does not compile with gcc 3.1 on cygwin.
If I use plain pointers it works as expected but not for shared_ptr.
What am I doing wrong?
/ Jonas
