c++11 - tbb unordered map hash function error -
i wish use concurrent_unordered_map custom types
i declare unordered map follows
typedef tbb::concurrent_unordered_map<openvdb::coord, std::vector<openvdb::vec3r>, anotherhashcompare> unordrd_vox_coordlist; where hash compare defined as
struct anotherhashcompare { static size_t hash( const openvdb::coord &x ) { size_t h = 0; int s; s=x.x(); h = (h*17)^s; s=x.y(); h = (h*17)^s; s=x.z(); h = (h*17)^s; return ((size_t)h); } //! true if strings equal static bool equal( const openvdb::coord &x, const openvdb::coord &y ) { return x==y; } };
now when want insert map object
unordrd_vox_coordlist intrmd_nrmls;
like this
intrmd_nrmls.insert(std::make_pair(it_rel_neigh->first,per_vox_intermed_nrmls));
where
per_vox_intermed_nrmls
is of type
std::vector
and
it_rel_neigh->first
is of type
openvdb::coord
i error follows

i tried declaring 2 new structs pass definition produces similar errors
does mean should declare them
struct myhashcpr_unordrd { static size_t hash( const openvdb::coord &x ) { size_t h = 0; int s; s=x.x(); h = (h*17)^s; s=x.y(); h = (h*17)^s; s=x.z(); h = (h*17)^s; return h; } }; struct myhasheqlty_unordrd { //! true if strings equal static bool equal( const openvdb::coord &x, const openvdb::coord &y ) { return x==y; } }; typedef tbb::concurrent_unordered_map<openvdb::coord, std::vector<openvdb::vec3r>, myhashcpr_unordrd,myhasheqlty_unordrd> unordrd_vec_of_coords; because produces following errors
