Hello *, I try to use a multi_index container with a composite key. The container is defined as follows: struct index_data { entry_header header; //has various public fields one of them is timestamp_ fs::entry entry; bool masked; }; typedef size_t timestamp_t; //in reallity this type is a class, but the error can be reproduced with this typedef as well timestamp_t const& timestamp(index_data const& data) { return data.header.timestamp_; } bool mask_state(index_data const& data) { return data.masked; } struct entry_data_tag {}; typedef mi::multi_index_container < index_data, mi::indexed_by < mi::ordered_non_unique < mi::tag<entry_data_tag> , mi::composite_key < mi::global_fun<index_data const&, bool, &mask_state> //this could be a direct member reference, but I intially used fusion::map and reduced the problem to minimum , mi::global_fun<index_data const&, timestamp_t const&, ×tamp> > > >
entry_index;
typedef entry_index::index<entry_data_tag>::type entry_data; void mask_all() { using namespace boost::lambda; entry_data& entries = pimpl_->indexed; entries.find(boost::make_tuple(false)); //!!!! this line results in an error novel by gcc 4.3 } The error description is: multi_index/composite_key.hpp:638: error: no match for 'operator*' in '*x' Does anyone have some suggestions why that happens? With Kind Regards, Ovanes
