Re: [Boost-users] Weak_ptr lost its operator==

Hi,

I just upgraded from boost 1.29 to boost 1.32, and found that operator== for weak_ptr has been dropped between these versions. My code uses std::find to find a weak_ptr in a container. This no longer compiles (g++-3.4.1) since find uses operator==. Has anyone else encountered this kind of problem? What are some good workarounds? Could operator== be put back?

Thanks, Brian

Make use weak_ptr::operator< (which IS in 1.32) by using std::lower_bound. You'll still have to check for 'equality' of the returned pointer (use !(A<B || B<A) for that). HTH Stuart Dootson
