Hi ! The lastest changes to Boost.SharedPtr seem to have broken spirit compiliation. I get: boost/boost/spirit/core/non_terminal/impl/grammar.ipp:232: error: 'make_shared' is not a member of 'boost' /boost/boost/spirit/core/non_terminal/impl/grammar.ipp:234: error: 'make_shared' is not a member of 'boost' I think that Peter Dimov removed "make_shared" from weak_ptr.h. Could someone with more insight in both libs fix this ? Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold ! Ingenieurgesellschaft für * voice: ++49 511 262926 57 !
