Hi, I'm getting the following error on Linux 2.2.16 / Suse 7.0 / g++ 2.95.2 / glibc 2.1.3: ../../../../../include/boost/pool/detail/ct_gcd_lcm.hpp:43: sorry, not implemented: `static_cast_expr' not supported by dump_expr ../../../../../include/boost/pool/detail/ct_gcd_lcm.hpp:43: sorry, not implemented: `static_cast_expr' not supported by dump_expr The following patch fixes it: --- include/boost/pool/detail/ct_gcd_lcm.hpp.orig Thu Dec 19 15:10:54 2002 +++ include/boost/pool/detail/ct_gcd_lcm.hpp Thu Dec 19 14:58:41 2002 @@ -38,7 +38,7 @@ BOOST_STATIC_CONSTANT(unsigned, A_mod_B_ = A % B); BOOST_STATIC_CONSTANT(unsigned, value = (::boost::details::pool::details::ct_gcd_helper< - B, static_cast<unsigned>(A_mod_B_), + B, A_mod_B_, ::boost::type_traits::ice_eq<A_mod_B_, 0>::value >::value) ); }; What is the cast good for anyway? It seems redundant.
